Description

UN CURRENCY (VIRTUAL PAYMENT CARDS) ISSUED BY CENTRAL BANK OR OTHER ISSUER FOR MOBILE AND WEARABLE DEVICES

FIELD

[0001] This application relates generally to data processing, and more specifically, to systems and methods for performing digital currency transfer via mobile and wearable devices.

BACKGROUND

[0002] In applying for a payment card, a customer usually has to physically visit a bank, spent some time there filling out a plurality of bank forms and standing in queues. Subsequently, the bank processes a credit card application by evaluating the creditworthiness of an applicant, verifying his credit history and employment information. In addition, the processing of payment cards, for example, carving names and card numbers on a credit card and storing magnetic information on a magnetic stripe of the card, takes a certain amount of time.

[0003] Thus, obtaining a payment card after filing an application may be a long-lasting procedure. However, customers may desire to receive a payment card immediately. Additionally, the customers may want to avoid formalities related to issuance of physical plastic payment cards and performing transfers.

DETAILED DESCRIPTION

[0019] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the presented concepts. The presented concepts may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail so as to not unnecessarily obscure the described concepts. While some concepts will be described in conjunction with the specific embodiments, it will be understood that these

embodiments are not intended to be limiting.

[0020] Various computer implemented methods and systems for digital currency transfers via a mobile and wearable device are described herein. The digital currency may be issued for a user based on financial data of the user stored or collected by a third-party organization. Therefore, though the user may have an account opened in the third-party

organization, there may be no need to issue physical plastic currency, such as Visa, Master Card, American Express, and so forth.

[0021] The digital currency may be an electronically issued currency having a unique currency number. The unique currency number may be generated for a specific transaction only. The unique currency number may be electronically generated on request from a web service or a mobile application running on a mobile and wearable device of the user and being in communication with a currency issuance unit. The currency issuance unit may include a bank, Federal Reserve Bank, cryptocurrency issuance unit, or any other third-party organization. The digital currency may be issued for the exact amount of the transaction. Thus, the possibility of fraud related to the account of the user opened in the bank may be significantly reduced. Furthermore, though inherent risks involved with credit currency usage exist, a digital currency may eliminate the risk of compromising the account. More specifically, the digital currency may be generated for a specific transaction or for several transactions within a predetermined time and, after the transaction is completed, the digital currency may become invalid. Therefore, even though data associated with the digital currency may be stolen, the data of the account of the user in the bank cannot be accessed using the stolen data because the digital currency may be deactivated.

[0022] Additionally, the user may control spending parameters associated with the digital currency. More specifically, the user may set restrictions related to the digital currency. The restrictions may include a specific money amount allowed to be spent, a range of the money amount allowed to be spent, the number of times the digital currency can be used, such as for a one-time payment or for a payment within a predetermined time limit, persons allowed to use the digital currency, such as a primary holder of the account and a secondary holder of the account, places where the digital currency may be used, such as a specific merchant. By using the restrictions, a risk of an unauthorized use of the digital currency may be reduced.

[0023] The digital currency may be also useful for companies and businesses. More specifically, paying bills by a company using a digital currency may result in cost savings, such as money costs related to issuance of physical cards and time and resource saving related to actions taken by a staff of the company. Additionally, a rebate may be provided to the user or the company based on the amount of money spent using the digital currency.

[0024] Further, the user may make person-to-person transfers without revealing his banking details. Instead, payment data of the user may be provided in the form of a scannable optical code on a screen of a mobile and wearable device associated with the user.

[0025] Moreover, the user may monitor the amount of money spent using the digital currency. Since one digital currency unit is generated for each specific transaction, the generated digital currency may be

electronically tracked and reconciled by the currency issuance unit and a report related to the use of digital currency may be provided to the user. Furthermore, analysis of the use of the digital currency by the user may be performed. The analysis may include evaluation of spending of money by the user for a specific time period, the list of recipients that accepted transfers using the digital currency, an average amount transferred to each of the recipients, and the like. In fact, the user may use the digital currency for performing payments related to electronic accounts associated with a plurality of merchants, corporate travel payments, mobile payments, person-to-person transfers, split payments, refunds, reimbursements, fees payments, and so forth.

[0026] Referring now to the drawings, FIG. 1 illustrates an environment 100 within which a system and a method for digital currency transfers via a mobile and wearable device can be implemented. The environment 100 may include a network 110, a user 120, a mobile and wearable device 130, a recipient 140, a device 150 associated with recipient 140, and a system 200 for digital currency transfers via a mobile and wearable device, also referred to as the system 200. The system 200 may have a distributed architecture including a cloud-based application 160 running on the mobile and wearable device 130, and a storage unit 170 associated with the mobile and wearable device 130 of the user 120. The mobile and wearable device 130 may include a smartphone, a wearable device (e.g., augmented reality glasses, a smart watch), a tablet computer, a lap top, and so forth.

[0027] The device 150 associated with recipient 140 may include a smartphone, a wearable device (e.g., augmented reality glasses, a smart watch), a tablet computer, a lap top, a payment terminal, such as a point of sale terminal, a credit card terminal, a card reader, and any other device that interfaces with currency to make electronic funds transfers and connects to a data network.

[0028] The user 120 may access the cloud-based application 160 via the mobile and wearable device 130. The cloud-based application 160 may be provided on a display of the mobile and wearable device 130, or may be projected or otherwise displayed by the mobile and wearable device 130 via a web browser or through another way. The cloud-based application 160 may provide to the user 120 the interface 185. The cloud-based application 160 may include a file hosting service, which may offer cloud storage, file synchronization, personal cloud, and client software.

[0029] The user 120 may register with the cloud-based application 160 on the mobile and wearable device 130. During registration, the user may specify user identification data, payment data, and authentication information. The payment data and authentication information may include information related to a credit card account, a debit card account, a charge card account, a bank saving account, a bank checking account, an insurance account, a stored-value card account, a cryptocurrency account, or a digital mobile currency account, or another payment facility of the user. The payment data may be stored in on the mobile and wearable device 130 and the storage unit 170 in association with the user identification data, and authentication information. Upon activation of the cloud-based application 160, the user 120 may initiate a transfer request 180 on the mobile and wearable device 130 and specify a transfer amount. Further, user identification data may be entered by the user 120, retrieved from the memory of the mobile and wearable device 130, or captured by sensors associated with the mobile and wearable device 130, such as fingerprints scanner or face recognition scanners. The transfer request 180 including at least the transfer amount and the user identification data may be sent to the system 200. In response to the transfer request 180, the system 200 may retrieve the payment data of the user 120 associated with the identification data from the storage unit 170.

[0030] In some embodiments, based on the transfer request 180 the currency issuance unit 220 may generate the digital currency and provide the digital currency to the account associated with the user. The digital currency may include a UN currency, also referred herein to as UNPAY currency (UNPAY).

[0031] Based on the payment data and the transfer amount, the system 200 may generate an optical code encoding the payment data and the transfer amount and transmit the optical code to the mobile and wearable device 130. The optical code may be provided on a screen of the mobile and wearable device 130 to be scanned by the device 150 associated with the recipient 140. The optical code may include a linear dimensional code, a two-dimensional code, a snap tag code, a Quick Response (QR) code, and a three-dimensional (3D) UNcode. The optical code may be integrated in a virtual payment card in the form of a virtual currency note. The virtual payment card may be personalized with an image associated with the user 120. On scanning of the optical code, the payment data and the transfer amount encoded in the optical code may be extracted. [0032] Alternatively, the user 120 may put the mobile and wearable device 130 in a proximity to the device 150 to enable connection between the mobile and wearable device 130 and the device 150. The connection the mobile and wearable device 130 and the device 150 may be established through radio waves, contacts for direct electrical connection, data-strip reading, and so forth. The mobile and wearable device 130 and the device 150 may include one or more of a radio frequency identification chip, a Near Field Communication (NFC) chip, one or more contacts for direct electrical connection, a magnetic data strip, a holographic data strip, and so forth.

[0033] Upon establishment of the connection between the mobile and wearable device 130 and the device 150, the payment data and the transfer amount may be sent to the device 150 via the network 110.

[0034] Based on the payment data and the transfer amount extracted from the optical code or received via network 110 and recipient identification data stored on the device or entered by the recipient 140, a transfer receiving request may be created. The transfer receiving request may be then sent to the system 200. When the system 200 receives the transfer receiving request, the system 200 may access a user account maintained by the currency issuance unit 220. The transfer amount in the digital currency may be transferred to a recipient account associated with the recipient identification data.

[0035] The transfer performed using the digital currency may include an Internet payment, a scan code payment, a person-to-person payment, a buyer-to-merchant payment, a peer-to-peer payment, an in-application payment, a point-of-sale payment, a mobile payment, a wearable payment, a one-touch buying, and a digital wallet payment, and so forth. The payment details may be stored in the cloud storage 170, which may be associated with the currency issuance unit 220, and provided via the cloud-based application 160 in a form of a virtual payment card only to perform the transaction. Thus, the payment details of the user 120 may be protected from a theft or fraud.

[0036] Communication between the mobile and wearable device 130, the system 200, and the currency issuance unit 220 may be performed via a network 110. The network 110 may include the Internet or any other network capable of communicating data between devices. Suitable networks may include or interface with any one or more of, for instance, a local intranet, a Personal Area Network, a Local Area Network, a Wide Area Network, a Metropolitan Area Network, a virtual private network, a storage area network, a frame relay connection, an Advanced Intelligent Network connection, a synchronous optical network connection, a digital Tl, T3, El or E3 line, Digital Data Service connection, Digital Subscriber Line connection, an Ethernet connection, an Integrated Services Digital Network line, a dial-up port such as a V.90, V.34 or V.34bis analog modem

The storage unit 230 of the system 200 may be operable to store at least the user identification data, the user authentication information, the digital currency, the recipient identification data, and any other information related to the user, the recipient, or a payment transaction. [0039] FIG. 3 is a flow chart illustrating a method 300 for digital currency transfers via a mobile and wearable device, in accordance with certain embodiments. The method 300 may commence with receiving over a data network, by a processor, from the mobile and wearable device of a user, a transfer request at operation 302. Transfer request may include a transfer amount in digital currency and user identification data associated with the user. The digital currency may be issued based on the transfer request in the amount corresponding to the transfer amount and deposited to an account associated with the user.

[0040] In some embodiments, the user may be prompted to enter user authentication information. The user authentication information may be received from the user by the processor. In an example embodiment, the user authentication information includes one or more of the following: a name of the user, an address of the user, a guarantor name, a social security number of the user, a phone number of the user, an identification number of the user, a bank account of the user, an insurance account number of the user, a photograph of the user, an email account of the user, biometric authentication, and so forth. The biometric authentication may include one or more of a fingerprint authentication, authentication based on facial recognition, an iris pattern authentication, a heartbeat authentication, and a vein pattern identification. The vein pattern identification may be performed using scanning of one or more of the following: a palm vein pattern, a wrist vein pattern, a hand vein pattern, a leg vein pattern, a foot vein pattern, a neck vein pattern, and a head vein pattern. The fingerprint authentication may include scanning fingerprints of at least one finger of the user when the user touches one or more or the following: the display of the mobile and wearable device, a button of the mobile and wearable device, a rear panel of the mobile and wearable device, and the like. The fingerprint authentication may further include matching the fingerprints to one or more approved fingerprints. The one or more approved fingerprints may be stored in the cloud storage. Authentication based on facial recognition may include three-dimensional (3D) face recognition, where information of the shape of a face is captured using 3D sensors and compared to one or more approved faces. The one or more approved faces may be stored in the cloud storage.

[0041] The method may continue with retrieving, from a storage unit, payment data of the user associated with the identification data in response to the transfer request. The payment data may include a payment account associated with a credit card or a debit card of the user. In an example embodiment, the payment data may include data associated with one or more of the following: a credit card, a debit card, a retail card, a charge card, a bank saving account, a bank checking account, an insurance account, a stored-value card, a digital mobile currency, a cryptocurrency account, and so forth. The currency issuance unit may be selected from one or more of the following: a bank, Federal Reserve Bank, a credit card company, an insurance company, a credit union, a store, a third-party organization, a public transaction database, a distributed ledger, and so forth.

[0042] The method 300 may further include an operation 306, at which based on the retrieving, an optical code encoding the payment data and the transfer amount is generated. At operation 308, the optical code may be provided on a screen of the mobile and wearable device. The optical code may include one or more of the following: a linear dimensional code, a two-dimensional code, a snap tag code, a QR code, 3D UNcode, and so forth. The optical code may be included in a virtual payment card associated with the transfer amount and the digital currency. The virtual payment card may be displayed via an interface of the mobile and wearable device. The virtual payment card may be read by a device associated with the recipient. In a further example embodiment, the payment data and the transfer amount associated with the transfer may be transmitted from the mobile and wearable device to the device associated with the recipient using an NFC upon bringing the mobile and wearable device and the device associated with the recipient into proximity to each other.

[0043] More specifically, the method 300 may include receiving an indication that the user brings the mobile and wearable device in proximity to the device associated to initiate sending data related to the transfer to the recipient. The indication may be received based on sensing an interaction of the mobile and wearable device with the merchant device. The interaction may include at least an NFC. The NFC may be used to pair the mobile and wearable device and the device upon bringing the mobile and wearable device into proximity to the device. The mobile and wearable device and the device may be connected to a cloud network. Upon pairing the mobile and wearable device with the device, at least a Bluetooth connection between the mobile and wearable device and the device may be established.

[0044] On obtaining the payment data and the transfer amount, a transfer receiving request may be created using the payment data, the transfer amount, and the recipient identification data.

[0045] The method 300 may further include, receiving a transfer receiving request to perform a payment transaction associated with the user at operation 310. The transaction request may include at least the payment data, the transfer amount, and recipient identification data associated with a recipient. The recipient identification data may be retrieved from the device associated with the recipient.

[0046] Further, the method may include accessing, by the processor, a user account maintained by a currency issuance unit at operation 312. The accessing may be performed based on the user authentication information provided by the user.

[0047] Digital currency is an asset represented in the digital form and having one or more monetary characteristics. Digital currency may be denominated to a sovereign currency and issued by a currency issuance unit responsible to redeem digital money for cash. Digital currency issued by country Central Bank (e.g. Federal Reserve Bank, European Central Bank, Bank of Canada, People's Bank of China, a central bank of 206 countries, other legal authorities, etc.) is a legal tender. Similar to the paper notes and coins, digital currency or digital money exhibits properties. At the same time the digital currency may allow for instantaneous transactions and borderless transfer-of-ownership. Both virtual currencies and

cryptocurrencies are types of digital currencies. Like traditional money, the virtual or digital currency may be used to buy physical goods and services while being restricted to certain communities, such as, for example for use inside an on-line game community or a social network.

[0048] There are more than trillion United States currency banknotes issued. An estimated cost for printing and circulation of every paper note is about 25 cents. Every five years a paper note must be reprinted again. In contrast to a paper note, the price of issuing digital money may be less than one cent. The use of digital currency may reduce the number of bank branches and ATM machines. Issuing digital currency per client request using client's mobile device may result in replacing transactions performed via physical plastic cards with transactions in digital currency.

[0049] In the present disclosure, the terms "UN currency" and "UN currency" mean "universal currency," "united currency," or "union currency." The terms "universal currency," "united currency," and "union currency" may be used interchangeably throughout the present disclosure and refer to digital currency that may include a universal currency used in a plurality of countries (e.g., all counties of the words, a portion countries of the word), a plurality of geographic regions, continents, or parts of the world (e.g., Europe, Asia, Eurasia, America, Oceania, and the like), and one or more currency unions (e.g., Eurozone). For example, the euro is the official currency of 19 of 28 member states of the European Union and some of the territories of the European Union, this group of states is known as the eurozone or euro area. Similarly, to the euro used in a number of countries, the UN currency may be used throughout the whole world. In an example embodiment, the UN currency may include one or more of physical currency available in form of banknotes and coins and digital currency available in digital form. Therefore, the UN currency may be an official digital currency of a group of 206 countries and one or more territories of the Earth. The group of countries may be known as a UN zone or a UN area and may be associated with the largest most traded digital currency market.

[0050] The UN currency may facilitate electronic funds transfers throughout the world using one or more of UN-branded credit cards, gift cards, and debit cards, UN issues cards, extend credits and set rates and fees for customer. The UN currency may provide financial institutions with UN- branded payment products to be uses to offer credits, debits, prepaid and cash-access programs to the customers. Transaction in the UN currency worldwide may be processed through an UNPAY Net system at one or more secure facilities. The UN currency may be associated with UN data centers secured against natural disasters, crime, and terrorism, that may operate independently of each other and from external utilities, handle up to 35,000 simultaneous transactions and up to 100 billion computations every second. Every transaction may be checked past 500 variables including 100 fraud-detection parameters including a location and spending habits of the customers and a merchant location.

[0051] The UN currency may be associated with signed copies of sales drafts included in each customer monthly billing statement for verification purposes. The UN currency may be associated with a summary statement showing a posting date, a purchase date, a reference number, a merchant name, and a dollar amount of each purchase. The UN currency may be further associated with a calculation of a finance charge on an unpaid balance shown on a prior month statement, wherein the UN currency is associated with an average daily balance resulting in increased revenue for issuers by calculating a number of days each purchase was included on a prior month statement, in which transactions from previous and current billing cycles were used in the calculation. The UNPAY currency may have a set of rules that govern a participation of financial institutions in a payment system associated with UNPAY currency.

Acquiring banks may be responsible for ensuring that merchants comply with the rules. The rules associated with the UNPAY currency may address how a device holder or the cardholder is to be identified for security, how transactions are denied by a bank and how banks cooperate for fraud prevention, and how to keep identification and fraud protection standard and non-discriminatory. The rules may govern what creates an enforceable proof of authorization by the device holder or the cardholder. Furthermore, the rules associated with the UNPAY currency may prohibit merchants from imposing a minimum or maximum purchase amount in order to accept, by a user of a mobile or wearable device, from charging device holders, a fee for using UN virtual card payments. Additionally, a discount for users of the UNPAY currency may be permitted under the rules. Furthermore, the rules associated with the UNPAY currency may permit merchants to ask for a photo identification (ID). When the UN virtual card is signed, a merchant may not deny a transaction if a UN virtual cardholder refuses to show the photo ID. The rules may further include addition of exceptions for non- signed purchases by telephone or on the Internet, and an additional security system for purchases on the Internet is enforced.

[0052] The UNPAY currency may be associated with a contactless payment technology enabling device holders to wave a wearable device in front of contactless payment terminals without the need to physically swipe or insert a virtual card into a point-of-sale device, using RFID technology. The UNPAY currency may be associated with a chip-only and a PIN-only debit card.

[0053] Additionally, the UNPAY currency may be associated with a mobile payment application or a wearable device application enabling payments via smartphones using a QR code and machine readable codes. In addition, the UNPAY currency may be associated with an UNPAY checkout system including an online or offline payment system for removing the need to share card details with retailers.

[0068] FIG. 4 is a schematic representation 400 of an interaction of a mobile and wearable device and a device during a digital currency transfer, in accordance with an example embodiment. In an example embodiment, a user initiates a transfer request, for example, by activating a cloud-based application (not shown) running on the mobile and wearable device 130.

The transfer request may be sent to the system 200 via the network 110. The system 200 may generate an optical code encoding the payment data and the transfer amount in digital currency.

[0069] The optical code may be provided on a screen of the mobile and wearable device 130. The user may bring the mobile and wearable device 130 in proximity of the device 150 associated with the recipient so that the mobile and wearable device 130 and the device 150 may establish a connection via scanning, NFC, RFID, and so forth. When the interaction is determined by the device 150, the device 150 may receive data associated with the transfer from the mobile and wearable device 130. In an example embodiment, the device 150 may include a mobile device 153, a point-of-sale card reader 155, a barcode reader 157, and so forth.

[0070] In an example embodiment, the data associated with the transfer may include a currency number 405, a name 410 of the user, and a code, such a barcode 415, a QR code 420, or a 3D UNcode 425. The 3D UNcode 425 may be associated with theUNPAY, a virtual currency issued and controlled by developers of the UNPAY, and used and accepted among members of a virtual community associated with the UNPAY.

[0071] The 3D UNcode may be readable by an imaging device and may include a round global circle and squares arranged in a round circle grid on a white background. Further, the 3D UNcode may be a machine- readable optical label encoding information in horizontal, vertical, and 3D components of the round global circle and squares arranged in a round circle grid. The information may be encoded using five standardized encoding modes including globeing, numeric, alphanumeric, byte/binary, and kanji to store data.

[0072] The application of the 3D UNcode may include product tracking, item identification, time tracking, document management, general marketing, payments, storing bank account information or credit card information, cryptographic currencies, and so forth. Payment addresses, cryptographic keys, and transaction information may be shared between digital wallets using the 3D UNcode.

[0073] Upon receipt of the data associated with the transfer, the device 150 may send the data associated with the transfer and the recipient identification information to the system 200 to complete the transaction.

[0074] The present disclosure further relates to a computer implemented method for multimedia capture, payment transactions, digital global ledger and national currency digital token for mobile and wearable devices. The method may include receiving, by one or more processors, a first input of a user. In response to the first input of the user, one or more sensors may be initiated to capture multimedia to obtain captured multimedia. The method may continue with receiving, by the one or more processors, a second input of the user. The first input of the user may include a touch engagement of the user with a display of a mobile and wearable device and the second input of the user may include a touch release of the user from the display of the mobile and wearable device. The method may further include analyzing, by the one or more processors, data associated with the first input of the user and the second input of the user. The analyzing may include determining time between the first input of the user and the second input of the user. Based on the analysis, a multimedia capture mode or a payment transaction mode may be selectively selected. The multimedia capture mode may be used to capture multimedia content. The selection of the multimedia capture mode and the transaction mode may be determined by comparison of the time between the first input and the second input with a predetermined time. Only a multimedia storing mode or a transaction mode can be selected at a single time. The

multimedia capture mode may be associated with a plurality of types of multimedia. Each of the plurality of types of multimedia may be

determined by the time between the first input and second input in the multimedia capture mode. Furthermore, based on the analysis, one of multimedia storing modes or a payment transaction mode may be selectively selected by the one or more processors. Each of the multimedia storing modes may be associated with at least one of a plurality of types of the multimedia. In response to the selection of the multimedia capture storing modes, the captured multimedia may be processed to obtain a type of the multimedia captured in the multimedia capture mode.

[0075] The method may continue with storing the type of the multimedia captured and the captured multimedia to a database to obtain a stored type of the multimedia. The method may further include receiving, in response to the selection of the payment transaction mode, transaction data. The transaction data may include at least a payment amount and a recipient. Based on the transaction data, user payment data, and recipient payment data, a payment transaction may be performed. The user payment data and the recipient payment data may be stored in the database.

[0076] The mobile and wearable devices may include at least one of a handheld computing device, a smartphone, a tablet computer, a personal digital assistant, a e-textile item, an activity tracker, a smartwatch, smartglasses, a Global Positioning System (GPS) watch, a mixed reality device, a computer-mediated reality device, a clothing technology device, and a wearable device, the wearable device having a band adapted to secure the wearable device on a human body, the human body may include a wrist, an arm, a neck, a head, a leg, a waist, an ear, a finger, and any other part of the human body. The band may be adapted to secure the wearable device under, within or on clothing, and wherein the band includes a rechargeable battery configured to power the wearable device.

[0077] The method may further include the use of a digital currency.

More specifically, the method may include receiving, by at least one processor, a transfer request. The transfer request may be authorized upon receiving authorization data from a sender having a sender account from which funds are transferred from. The authorization data may include a password, personal identification number (PIN) code, and biometric data comprising a face of the sender. Based on the receiving, the sender may be authorized to provide the transfer request when the authorization data provided for the transfer request matches previously registered

corresponding authorization data. The transfer may be associated with an amount represented in tokens of the digital currency stored on the mobile and wearable device of the sender. The transfer request may include at least the sender account, a recipient account, and the amount. Based on the transfer request, prior to transferring, the digital currency may be encrypted by assigning a unique key to the transferring and signing the digital currency using a cryptographic signature the amount from the sender account to the recipient account. The tokens stored on the mobile and wearable device of the sender may be printed with a face of the sender.

Upon transfer from the mobile and wearable device of the sender to a mobile and wearable device of the recipient, the tokens may be converted by replacing the senders face with the recipient face. The digital currency may be not a currency of any national government but may be operable to be exchanged by the mobile device into a user defined national currency. [0078] Transactions in the digital currency between parties may be recorded in a distributed world global digital currency ledger. The distributed world global digital currency ledger may be programmed to trigger transactions between the parties automatically using a peer-to-peer network, a distributed timestamping server, and a code block file chain database including a transaction database for using the digital currency.

The digital currency may be associated with an exchange rate between two digital currencies. The exchange rate is a rate at which one digital currency is exchanged for another digital currency. The exchange rate may be determined in a foreign exchange market, the foreign exchange market being open to a plurality of types of buyers and sellers. A currency trading may be continuous, i.e. may last for days and nights without interruption. The exchange rate may include a spot exchange rate associated with a current exchange rate. The exchange rate may further include a forward exchange rate including an exchange rate that is quoted and traded on a current date for delivery and payment on a specific future date. The exchange rate may further include a buying rate and a selling rate. The buying rate is a rate at which a person buys foreign currency in exchange for the digital currency, and the selling rate is a rate at which the person sells the digital currency.

[0079] FIG. 5 illustrates a schematic representation 500 of interactions between a user device 130 and a device 150 associated with the recipient, in accordance with an example embodiment. The screen of the user device 130 may display a virtual payment card 502 representing the digital currency, in which the transfer is being performed. Though the digital currency may be available only in digital form and may have no physical form, virtual payment cards representing the digital currency may be similar to a note of physical currency, for example, a US currency banknote. Additionally, the virtual payment cards may provide personalization options not available with physical currency banknotes even for governors or presidents of the countries issuing the physical currency. For example, the user may his face on a virtual currency card resembling a banknote of a physical currency as shown on FIG. 5.

[0080] Further, a virtual payment card may include two sides, one showing a total balance on an account associated with the user and resembling a banknote of a physical currency personalized with an image provided by the user, for example, an image of the President of the United States of America, Donald Trump. The other side may be provided on a touch interaction with the screen of user device 130 and personalized with an image of the user to authorize the transaction based on face recognition.

[0081] The virtual payment card 502 may include an image 504 associated with the user, a transfer amount 506, and an optical code 508 encoding transfer data.

[0082] Upon scanning of the optical code 508 by the device 150, the transfer data is derived from the optical code 508. Based on the deriving, a virtual payment card 510 may be generated and displayed on the screen of the device 150 via the interface of the cloud-based application related to the recipient. In an example embodiment, the virtual payment card 510 may be personalized with an image 512 associated with the recipient. Further, the transfer amount 506 may be converted based on a currency associated with the cloud-based application related to the recipient. The virtual payment card 510 may include a converted amount 514. Further, the device 150 may include a Subscriber Identity Module card 516, via which the device 150 may communicate with the network. [0083] FIG. 6 illustrates further representations 600 of virtual payment cards, in accordance with an example embodiment. A virtual payment card 602 may be personalized using an image embedded in an optical code. The user may provide at least one image to be depicted on the virtual payment card 602. The image may include an image of a face of the user, an image of a public figure, e.g. current President Donald Trump, an image of a movie character, and other images with optical code like ID, 2D and 3D UNcode associated with UNPAY.

[0084] In another embodiment, a virtual payment card 604 may be similar to a note in a physical currency. The virtual payment card 604 may include one or more optical codes.

[0085] FIG. 7 illustrates a schematic representation 700 of UNcode

702, in accordance with an example embodiment. The UNcode 702 may include a three-dimensional representation of data readable by machine.

[0086] FIG. 8 illustrates various representations 800 of digital currency, in accordance with an example embodiment. Representations 800 show user interfaces of a mobile and wearable device, such as a smartphone, including optical codes encoding data associated with the user. The user interfaces may include an interface 802 with a barcode, an interface 804 with a QR code, an interface 806 with a UNcode, an interface 808 with a QR code integrated into an image provided by the user, an interface 810 with an image provided by the user integrated in a QR code, an interface 812 with a QR code integrated into an image provided by the user, an interface 814 with an image provided by the user integrated in a QR code, an interface 816 with a barcode and a QR code. In an example embodiment, user interfaces may include settings associated with digital and virtual payments. Example settings may include setting percentage of a tip to be added to the payment and specifying a number of persons, between which the payment is to be split. In an example embodiment, an application running on the mobile and wearable device and associated with a system for digital currency transfers via the mobile and wearable device may be referred to as "UNPAY," as shown by element 820.

[0087] FIG. 9 illustrates various representations 900 of digital currency, in accordance with an example embodiment. Representations 900 show user interfaces of a mobile and wearable device, such as a smart watch, including optical codes encoding data associated with the user. The user interfaces of a smart watch may include an interface 902 with a barcode and a QR code, an interface 904 with a barcode, an interface 906 with a QR code, an interface 908 with a UN code, an interface 910 with a QR code integrated into an image provided by the user, an interface 912 with an image provided by the user integrated in a QR code. In an example embodiment, user interfaces may include settings associated with digital and virtual payments. Example settings may include setting percentage of a tip to be added to the payment and specifying a number of persons, between which the payment is to be split.

[0088] The digital currency may include virtual currencies, cryptocurrencies, digital money, electronic money, electronic currency or central bank issued digital base money, a money balance recorded electronically on a stored-value card, virtual payment card or mobile and wearable devices. Another form of digital electronic money is network money, allowing the transfer of value on computer networks, particularly the Internet. Digital money can either be centralized, where there is a central point of control over the money supply, or decentralized, where the control over the money supply can come from various sources in a global computer digital ledger.

[0089] The digital currency may be a type of currency, available in a digital form and not available in physical form, which exhibits properties similar to physical currencies and allows for instantaneous transactions and borderless transfer-of-ownership. Like traditional money, the digital currency may be used to buy physical goods and services. In an example embodiment, the digital currency may be restricted to certain communities, such as for use inside an on-line game or social network.

[0090] The digital currency may be a digital asset designed as a decentralized cryptocurrency to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets. The cryptocurrency may be classified as a subset of digital currencies and as a subset of alternative digital currencies and virtual currencies. The cryptocurrency may use decentralized control as opposed to centralized electronic money and central banking systems. The decentralized control of the cryptocurrency works through a code block file chain (BLOCKCHAIN), which is a public transaction database, functioning as a

distributed ledger with private key to perform peer to peer transactions.

[0091] In an example embodiment, the BLOCKCHAIN is a global public ledger for digital currencies of 206 countries. The BLOCKCHAIN records digital currencies transactions without any trusted international central authority: the maintenance of the BLOCKCHAIN is performed by a network of communicating nodes running BLOCKCHAIN software. Transactions of in the digital currency are broadcast to BLOCKCHAIN network using readily available software applications. BLOCKCHAIN network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. The BLOCKCHAIN may be a distributed database - to achieve independent verification of the chain of ownership of any and every digital currency amount, each network node may store its own copy of the BLOCKCHAIN. A new group of accepted transactions, a block, may be created substantially multiple time during an hour, added to the BLOCKCHAIN, and published to all nodes. This allows digital currency software to determine when a particular digital currency amount has been spent, which is necessary in order to prevent double-spending in an environment without central oversight. Whereas a conventional ledger records the transfers of

actual bills or promissory notes that exist apart from it,

the BLOCKCHAIN is the only place that digital currency can be said to exist in the form of unspent outputs of transactions.

[0092] In an example embodiment, the digital currency includes a

UNPAY. The UNPAY may be a combined digital currency of 206 countries. UNPAY transactions may be defined using a Forth-like scripting language and consist of one or more inputs and one or more outputs. When a user sends digital currency, the user designates each address and the amount of digital currency being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the

BLOCKCHAIN. The use of multiple inputs corresponds to the use of multiple UNPAY in a cash transaction. Since transactions may have multiple outputs, users can send UNPAY to multiple recipients in one transaction. As in a cash transaction, the sum of inputs (UNPAY used to pay) can exceed the intended sum of payments. In such a case, an

additional output is used, returning the change back to the payer. Any input not accounted for in the transaction outputs become the transaction fee. Paying a transaction fee is optional, users can choose which

transactions to process and prioritize those that pay higher fees. Fees are based on the storage size of the transaction generated, which in turn is dependent on the number of inputs used to create the transaction.

[0093] In the BLOCKCHAIN, UNPAY is associated with UNPAY owner addresses. Creating a UNPAY address includes picking a random valid private key and computing the corresponding UNPAY owner address. This computation can be done during a time period substantially less than a second. But the reverse (computing the private key of a given UNPAY address) is mathematically unfeasible. So, users can tell others and make public a UNPAY address without compromising its corresponding private key. Moreover, the number of valid private keys is so vast that it is extremely unlikely someone can compute a key-pair that is already in use and has funds. The vast number of valid private keys makes it unfeasible that brute force could be used for that. To be able to spend the UNPAYs, the owner needs to know the corresponding private key and digitally sign the transaction. The network verifies the signature using the public key. If the private key is lost, the BLOCKCHAIN network or UNPAY network does not recognize any other evidence of ownership; the UNPAYs are then unusable, and effectively lost.

[0094] In an example embodiment, the mobile or wearable device includes a virtual wallet which stores the information necessary to transact UNPAYs, for example, the digital credentials for users holdings and allows one to access (and spend) UNPAYs. While wallets are often described as a place to hold or store UNPAYs, due to the nature of the system, UNPAYs are inseparable from the BLOCKCHAIN. [0095] UNPAY may use public-key cryptography, in which two cryptographic keys, one public and one private, are generated. At its most basic, a wallet may be a collection of these keys.

[0096] The virtual wallet may include several types of wallets:

software wallets, online wallet, and a physical wallet. Software wallets may connect to the network and allow spending UNPAYs in addition to holding the credentials that prove ownership. Software wallets can be split further in two categories: full clients and lightweight clients.

[0097] Full clients may be a secure and reliable way of using the network, as trust in external parties is not required. They may verify transactions directly on a local copy of the BLOCKCHAIN or a pruned subset of the UNPAY network. Full clients may check the validity of UNPAY blocks, preventing them from transacting on a chain that breaks or alters network rules. Because of its size and complexity, storing the entire BLOCKCHAIN is not suitable for all computing devices.

[0098] Lightweight clients, on the other hand, may consult full clients to send and receive transactions without requiring a local copy of the entire BLOCKCHAIN. This makes lightweight clients much faster to set up and allows them to be used on low-power, low-bandwidth devices such as smartphones. When using a lightweight wallet, however, the user needs to trust the server to a certain degree, as it can report faulty values back to the user. Lightweight clients may follow the longest BLOCKCHAIN and do not ensure it is valid, requiring trust in system UNPAY users.

[0099] With both types of software wallets, the users are responsible for keeping their private keys in a secure place.

[00100] Besides software wallets, Internet services called online wallets may offer similar functionality, but may be easier to use. In this case, credentials to access funds may be stored with the online wallet provider rather than on the user's hardware. As a result, the user should complete trust in the wallet provider.

[00101] Physical wallets store the credentials necessary to spend UNPAYs offline. Examples combine a novelty UNPAY with these credentials printed on metal. Paper wallets may include paper printouts.

[00102] UNPAY may have a pseudonymous privacy, which means that funds are not tied to a central bank or real-world entities, but rather UNPAY addresses. UNPAY owners of UNPAY addresses may be not explicitly identified, but all transactions on the BLOCKCHAIN may be public. In addition, UNPAY transactions can be linked to individuals and companies through idioms of use, transactions that spend UNPAYs from multiple inputs may indicate that the inputs may have a common owner and corroborating public transaction data with known information on owners of certain addresses. Additionally, UNPAY exchanges, where UNPAYs are traded for traditional currencies, may be required by law to collect personal information.

[00103] In an example embodiment, to heighten financial privacy, a new UNPAY address may be generated for each transaction. Specifically, hierarchical deterministic wallets may generate pseudorandom, rolling addresses for every transaction from a single seed, while only requiring a single passphrase to be remembered to recover all corresponding private keys. UNPAY exchanges and other entities may prove assets, liabilities, and solvency without revealing their addresses using zero-knowledge proofs.

[00104] The validity of each UNPAY unit may be provided by the BLOCKCHAIN. The BLOCKCHAIN is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block may contain a hash pointer as a link to a previous

block, a timestamp and transaction data. The BLOCKCHAIN is resistant to modification of the data. It may be an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. For use as a distributed ledger, the BLOCKCHAIN may be managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.

[00105] In an example embodiment, a banking account may be associated with a digital or virtual currency account providing for transactions between these accounts. Such transactions, peer-to-peer transfers, and other services related to the digital currency network may be free of any fees. The services related to the digital currency network may be provided on a subscription basis. Subscribers may be identified with one or more of the following: an email address and a mobile phone number. The user may perform a transfer with only an email address or a mobile phone number of a recipient on condition that the recipient is registered with the digital currency network and has an email address and a mobile phone number specified as his identifier.

[00106] In some example embodiments, the BLOCKCHAIN is a distributed computing system with high Byzantine fault tolerance.

Decentralized consensus may be achieved with the BLOCKCHAIN. It may solve the double spending problem without the need of a trusted authority or central server. [00107] A block time is the average time it takes for the network to generate one extra block in the BLOCKCHAIN. By the time of block completion, the included data becomes verifiable. This is practically when the money transaction takes place, so a shorter block time means faster transactions.

[00108] UNPAY may use various time stamp schemes to avoid the need for a trusted third party to timestamp transactions added to the BLOCKCHAIN ledger. Securing a UNPAY cryptocurrency network and achieving distributed consensus may be implemented through requesting users to show ownership of a certain amount of currency or running hashing algorithms to validate electronic transactions.

[00109] In an example embodiment, UNPAY mobile or wearable cryptocurrency wallet stores the public and private keys or UNPAY addresses, which can be used to receive or spend the UNPAY

cryptocurrency. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.

[00110] UNPAY cryptocurrency may be pseudonymous rather than anonymous in that the UNPAY cryptocurrency within a wallet may be not tied to people, but rather to one or more specific keys or UNPAY addresses. Thereby, UNPAY cryptocurrency owners may be not identifiable, but all transactions may be publicly available in the BLOCKCHAIN. Still, UNPAY cryptocurrency exchanges may be required by law to collect the personal information of their users.

[00111] UNPAY digital currency may include a virtual currency or virtual money, which is issued and controlled by its developers, and used and accepted among the members of a specific virtual community. The virtual currency may be a digital representation of value which is accepted by natural or legal persons as a means of payment and can be transferred, stored or traded electronically.

[00112] FIG. 10 shows a diagrammatic representation of a machine in the example electronic form of a computer system 1000, within which a set of instructions for causing the machine to perform any one or more of the methodologies discussed herein may be executed. In various example embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a personal computer (PC), a tablet PC, a set-top box (STB), a cellular telephone, a portable music player (e.g., a portable hard drive audio device such as a Moving Picture Experts Group Audio Layer 3 (MP3) player), a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term "machine" shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.

[00113] The example computer system 1000 includes a processor or multiple processors 1002 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), or both), a main memory 1004 and a static memory 1006, which communicate with each other via a bus 1008. The computer system 1000 may further include a video display unit 1010 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 1000 may also include an alphanumeric input device 1012 (e.g., a keyboard), a cursor control device 1014 (e.g., a mouse), a disk drive unit 1016, a signal generation device 1018 (e.g., a speaker) and a network interface device 1020.

[00114] The disk drive unit 1016 includes a non-transitory computer- readable medium 1022, on which is stored one or more sets of instructions and data structures (e.g., instructions 1024) embodying or utilized by any one or more of the methodologies or functions described herein.
