Description

SYSTEM AND METHOD FOR COMPLETING A TRANSACTION

FIELD OF THE INVETNION:

[0001] The present disclosure relates to point of sale terminal systems and mobile payment systems and more particularly relates to methods and systems for completing a transaction through Bluetooth™ low energy technology enabled facilitator device.

BACKGROUND TO THE INVENTION:

[0002] A cashless society generally describes an economic state whereby financial transactions are accomplished through the transfer of digital information (electronic representation of money) between the transacting parties. In last few decades, use of non- cash transactions and digital payment methods were widespread in many countries, with intermediaries such as digital wallet systems operated by companies, contactless and NFC payments by electronic cards or smartphones, etc. Mobile communication devices such as smartphones, personal digital assistants and the like are increasingly being used to conduct payment transactions while purchasing products or services online or during order fulfilment for products or services provided in retail locations, such as grocery stores, restaurants, fast food chains, coffee shops and other retail establishments.

[0003] Generally, most of the retail establishments utilize point of sale terminals (POS terminals) for completing transactions. A point of sale terminal typically include an internet enabled computer, a barcode scanner, a credit/debit card reader, a printer and other equipment or software used for completing a transaction between the retail establishment and a customer. During the transaction, the merchant calculates an amount owed by the customer by scanning the product barcode, prepares an invoice for the customer and indicates one or more options for the customer to make payment. The one or more options may include one of a cash payment, credit/debit cards, cash cards, digital wallets, online payments, etc. More advanced point of sale terminals use near field communication (NFC) technology that allows communication between the point of sale terminal and an NFC enabled smartphone to complete the transaction. Further, few smartphones utilize magnetic secure transmission (MST) technology using which the smartphone emits a magnetic signal that simulates the magnetic strip found on the back of a credit or debit card. Then the transaction is completed by the point of sale terminal by processing the credit or debit card information.

[0004] Hence, with the conventional point of sale terminals, the consumers may use many different payment methods such as credit/debit cards, online banking, stored value cards, payment wallets, and the like, to complete to complete a transaction. As described, the customer account identifiers and other data represented by the cards are communicated to the point of sale terminal via magnetic stripes, near field communication technologies, manual input, and other suitable mechanisms. Then the transaction is completed by the point of sale terminal by processing the account identifiers and other data represented by the cards.

[0005] In order to accomplish the transaction, the conventional point of sale terminals requires a reliable internet connection and an internet service provider (ISP). Further, standard point of sale terminals comprising a computer, digital touchscreen interface, scanner, printer, cards processors and other peripherals are costly and are expensive particularly for businesses or vendors. Furthermore, the conventional point of sale terminals require periodic software upgrades, vendors have to pay for new licenses or monthly subscription fees and hence involves additional post deployment maintenance cost. Furthermore, customers who use their credit or debit cards when making their purchases run the risk of exposing their personal information (e.g. PINs) to other individuals (vendors). Further, the process of simple invoicing (calculation) and digital payment is decoupled in the conventional POS systems, hence the overall process is more cumbersome. Hence, small businesses face significant challenges in adapting to, and taking advantages of the conventional point of sale terminals.

[0022] Embodiments of the present disclosure will be described below in detail with reference to the accompanying figures.

[0023] The present disclosure relates to a system and method for completing a transaction in a retail environment, wherein the system comprises a facilitator device, a user device and an authentication server. The facilitator device at a merchant location generates a payload for a transaction, wherein the payload for the transaction comprises encrypted payment information. Upon generating the payload for the transaction, the facilitator device broadcasts its presence by means of a custom Bluetooth profile thereby enables a user device, which is in close proximity to the facilitator device, to establish a connection with the facilitator device. In a preferred embodiment of the present disclosure, the connection is established by the user device. In some implementations, the connection may be established by the facilitator device with the user device which is in close proximity to the facilitator device. Upon successful connection, the user device fetches the payload for the transaction from the facilitator device and communicates the same to the authentication server. The authentication server on the other hand, decrypts the payload for the transaction, authenticates the payload for the transaction (decrypted data) and communicates a result to the user device thereby enabling the user device to complete the transaction through any one of a payment mode such as but not limited to a payment wallet, credit/debit card, cash card, online transfer, unified payments interface (UPI), and the like. In a preferred embodiment of the present disclosure, the user device is configured to communicate a status of the transaction to the facilitator device and the facilitator device indicates the status of the transaction by means of one or more LEDs, textual display and the like.

[0024] Figure 1 illustrates an exemplary representation of a system for completing a transaction in accordance with an embodiment of the present disclosure. As shown, the system 100 comprises a facilitator device 105, a user device 110 and an authentication server 115, wherein the user device 110 and the authentication server 115 are communicatively connected through a communication network 120.

[0025] In one embodiment of the present disclosure, the facilitator device 105 is a re- implemented calculator configured for performing operations ranging from basic arithmetic to complex mathematics. In a preferred embodiment of the present disclosure, the facilitator device 105 is a portable re-implemented calculator carried by a merchant and typically configured for performing basic arithmetic operations such as addition, subtraction, multiplication and division, and optionally advanced operation such as manipulation of percentages. Further, the facilitator device 105 does not require internet connection or any data communication network to complete the transaction and hence operates as an independent device at the merchant location. In one embodiment of the present disclosure, the facilitator device 105 is assigned a unique ID (hereafter referred to as facilitator device ID) which uniquely identifies the facilitator device 105 among plurality of facilitator devices. Further, the facilitator device ID is mapped with the merchant information such as but not limited to merchant name, merchant address and contact details, location of the facilitator device (pre-configured region within which the facilitator device is operational), type of business, information pertaining to financial entity associated with the merchant, etc. The facilitator device ID and associated merchant information is recorded in the authentication server 115.

[0026] In one embodiment of the present disclosure, the facilitator device is a Bluetooth enabled device and comprises a custom key ("Pay" key), a custom transaction controller and a Bluetooth low energy beacon. During operation i.e., during a transaction, when the merchant calculates an amount owed by the customer and presses the pay button, the facilitator device generates a payload for the transaction. Further, the facilitator device 105 broadcasts a presence of a custom Bluetooth profile announcing the presence of the facilitator device 105 to the nearby Bluetooth enabled devices. In other words, the facilitator 105 broadcasts an advertisement data that announces the presence of the facilitator device 105 with a custom Bluetooth profile to the nearby Bluetooth enabled devices.

[0027] The user device 110 may be one of a smartphone, a personal data assistant (PDA) and the like, capable of connecting to the internet and having other communication capabilities. The user device 110 may communicate with the authentication server 115 through the communication network 120 in one or more ways such as wired, wireless connections or a combination thereof. It will be appreciated by those skilled in the art that the user device 105 includes one or more functional elements capable of communicating through the communication network 110 to receive one or more services offered by the authentication server 115. In one embodiment of the present disclosure, the user device 110 is a Bluetooth enabled device and communicates with the facilitator device 105, when the user device 110 is in close proximity to the facilitator device 105, to exchange data and hence builds a temporary personal area network.

[0028] In another embodiment of the present disclosure, the user device 110 comprises a payment application which enables a user to register with the system 100 by providing necessary registration credentials. The registration credentials may include a user name, password, contact details, payment details, and the like. Upon successful one time registration, the user may utilise the payment application to make payment to any of the merchant who uses the facilitator device 105. During operation, when the user launches and interacts with the application, for example, when the user selects an option "Pay", the payment application searches for facilitator devices nearby and establishes a Bluetooth connection with one of the facilitator device whose signal strength is greater than a predefined threshold signal strength. That is, the user device 110 compares signal strength of the received Bluetooth signal with the pre-defined threshold signal strength and establishes the Bluetooth connection if the signal strength of the received Bluetooth signal is greater than the pre-defined threshold signal strength. In some implementations, the facilitator device 105 is no longer visible or connectable to any other devices, once the facilitator device 105 establishes the connection with the use device 110. Upon successful connection, the user device 110 (payment application) fetches the payload for the transaction from the facilitator device 105 and communicates the payload for the transaction to the authentication server 115. Hence, only the connected user device is able to make the payment and complete the transaction. The facilitator device will does not accept payment from any other user devices until termination of the transaction or connection.

[0029] The communication network 120 may be a wireless network or a wired network or a combination thereof. Wireless network may include long range wireless radio, wireless personal area network (WPAN), wireless local area network (WLAN), mobile data communications such as 3G, 4G or any other similar technologies. The communication network 120 may be implemented as one of the different types of networks, such as intranet, local area network (LAN), wide area network (WAN), the internet, and the like. The communication network 120 may either be a dedicated network or a shared network. The shared network represents an association of the different types of networks that use a variety of protocols, for example, Hypertext Transfer Protocol (HTTP), Transmission Control Protocol/Internet Protocol (TCP/IP), Wireless Application Protocol (WAP), and the like. Further the communication network 120 may include a variety of network devices, including routers, bridges, servers, modems, computing devices, storage devices, and the like. In one implementation, the communication network 120 is internet which enables communication between the user device 110 and the authentication server 115.

[0030] The authentication server 115 may include, for example, a computer server or a network of computers or a virtual server which provides functionalities or services for other programs or devices such as for the user device 110 and to merchant devices, if any, for example, mobile device. In one implementation, the authentication server 1 15 is a cloud server comprising one or more processors, associated processing modules, interfaces and storage devices communicatively interconnected to one another through one or more communication means for communicating information. The storage associated with the authentication server 115 may include volatile and non- volatile memory devices for storing information and instructions to be executed by the one or more processors and for storing temporary variables or other intermediate information during processing. [0031] In one embodiment of the present disclosure, the authentication server 115 comprises a database that comprises information pertaining to one or more facilitator devices, wherein the information may include but not limited to, facilitator device ID and merchant information associated with the facilitator devices. As described, the merchant information comprises, but not limited to, merchant name, merchant address and contact details, location of the facilitator device (i.e., pre-configured region within which the facilitator device is operational), type of business, information pertaining to financial entity associated with the merchant such as merchant account number, branch, account type, etc. Further, the database maintains a record of information pertaining to the one or more user devices, wherein the information may include, but not limited to, user device ID (or payment application ID), user login credentials, user contact information such as phone number, email IDs, etc. That is, when a merchant subscribes for the system, the information pertaining to the facilitator device is recorded in the authentication server 115. Similarly, when a user installs payment application and registers with the system, the information pertaining to the user device is recorded in the authentication server 115. Hence, the system 100 provides a transaction platform for the subscribed merchants and the registered users to execute and complete the transactions.

[0032] As described, the user device 110 (payment application) fetches the payload for the transaction from the facilitator device 105 and communicates the payload for the transaction to the authentication server 115. The authentication server 115 decrypts the payload for the transaction, authenticates the payload for the transaction (decrypted data) and communicates a result to the user device 115 thereby enabling the user device 110 to complete the transaction through any one of a payment mode such as but not limited to a payment wallet, credit/debit card, cash card, online transfer, unified payments interface (UPI), and the like. As described, payload for the transaction comprises, encrypted payment information. In one embodiment of the present disclosure, the authentication server 115 decrypts the received payload for the transaction to determine the payment information, wherein the payment information comprises facilitator device information for example, facilitator device ID and at least an amount owed by the user. Up on decrypting, the authentication server 115 locates the user device 110 to determine a location of the facilitator device 105. That is, the authentication server 115 locates the user device 110 and compares the location of the user device 110 (i.e., location of the facilitator device 105) with the recorded location of the facilitator device, i.e., the pre-configured region within which the facilitator device 105 is operational or may operate. If the location of the facilitator device 105 is within the pre-configured region within which the facilitator device 105 is operational, then the authentication server 115 communicates a result to the user device 110 thereby enabling the user device 110 to complete the transaction, wherein the result comprises, at least one of an amount owed (amount to be paid by the user), breakup amount, the facilitator device ID and merchant information. In some implementations, the facilitator device 105 comprises a GPS module and the pay load for the transaction is authenticated by locating the facilitator device 105 and comparing the location with the pre-configured region within which the facilitator device 105 is operational or may operate.

[0033] Figure 2 illustrates a block diagram of an exemplary facilitator device in accordance with an embodiment of the present disclosure. As shown, the facilitator device 105 comprises basic blocks of a calculator such as a LCD display 205, a microcontroller 210, a keyboard matrix 215, a power supply 220 and a register array 225, for performing basic arithmetic operations on the user input. In one embodiment of the present disclosure, the facilitator device 105 further comprises a custom transaction controller 230, a Bluetooth low energy (BLE) beacon 235 and a LED module 240. In another embodiment of the present disclosure, the keyboard matrix 215 comprises a "Pay" key 245 using which the merchant may initiate a transaction.

[0034] During operation, when the merchant hits a key, the microcontroller 210 identifies the digit and activates appropriate segments on the display 205 corresponding to the digit. When the merchant hits subsequent digits, the microcontroller 210 displays on the display 205 and keeps doing this until the merchant hits one of the operations keys such as, '+', '-','*'and 7'. Once merchant hits any of the operations key, for example '+' , the microcontroller 210 stores the just entered number in one of the register in the register array 225. Further, once the merchant inputs a second number, the microcontroller 210 displays the number digit by digit and stores in a second register in the register array 225. When the merchant hits '=' key, the microcontroller 210 performs appropriate action on the content of the first and second register and displays a result on the display 205. In this example, the microcontroller 210 adds two number and displays the result on the display 205.

[0035] In one embodiment of the present disclosure, the transaction controller 230 is a microcontroller configured for generating the payload for the transaction, wherein the payload for the transaction comprises encrypted payment information. In some implementations, when the merchant calculates the final amount and hits 'pay' key 245 to initiate a transaction, the transaction controller 230 fetches the result from the controller 210 and encrypts the amount and the facilitator device ID to generate a payload for the transaction. Further, the transaction controller 230 triggers the Bluetooth low energy beacon (BLE beacon) 235.

[0036] In one embodiment of the present disclosure, the BLE beacon 235 broadcasts a presence of the facilitator device 105 to the nearby one or more user devices. In some implementations, the BLE beacon 235 uses Bluetooth low energy proximity sensing and broadcasts a presence of custom Bluetooth profile (payment service profile) announcing the presence of the facilitator device 105. In a preferred embodiment, a LED from the LED module 240 is activated to indicate the merchant about successful announcement.

[0037] Typically, in a merchant environment, there may be one or more of facilitator devices and one or more user devices. In such a scenario, a user who intends to pay brings his device (user device) in close proximity to one of facilitator device with which the user is executing the transaction. Then a connection is established between the user device and the facilitator device based on the received signal strength of the Bluetooth signal. The manner in which a connection is established between the facilitator device 105 and the user device 110, and the transaction is completed is described in detail further below.

[0038] Figure 3 is a flowchart illustrating a method of completing a transaction in accordance with an embodiment of the present disclosure. Figure 3 may be described from the perspective of the user device 110 that is configured to execute computer-readable instructions to establish a connection with the facilitator device 105 and to complete the transaction. In particular, the steps as described in Figure 3 may be executed for establishing a connection with the facilitator device, fetching payload for the transaction from the facilitator device, authenticating the payload for the transaction and complete the transaction upon successful authentication.

[0039] As described with reference to Figure 2, the BLE beacon 235 broadcasts the presence of the custom Bluetooth profile (payment service profile) announcing the presence of the facilitator device 105. A user who intends to pay brings his device (user device 110) in close proximity to the facilitator device 105. At step 305, the user device 110 compares received signal strength indication (value) of Bluetooth signal (RSSI) with pre-defined threshold signal strength. In one embodiment of the present disclosure, the pre-defined threshold signal strength is adjustable to set the proximity.

[0040] At step 310, if the received signal strength of the Bluetooth signal (signal strength of the received Bluetooth signal) is greater than the pre-defined threshold signal strength then control passes to step 315. Else, control passes to step 305 and the user device 110 notifies the user to bring the user device 110 close to the facilitator device 105. [0041] At step 315, the user device 110 establishes a connection with the facilitator device 105. In preferred embodiment of the present disclosure, a full duplex Bluetooth connection is established between the user device 110 and the facilitator device 105. In some implementations, the facilitator device 105 notifies the merchant about the connection establishment by turning on one or more LEDs from the LED module 240 or through textual display. Further, once the connection is established, the facilitator device 105 stops broadcasting the presence of the custom Bluetooth profile (payment service profile) announcing the presence of the facilitator device 105. Hence, the facilitator device 105 is no longer visible or connectable to any other user devices until the transaction completes or terminated by either by facilitator device 105 or the user device 110. In an advantageous embodiment of the present disclosure, the facilitator device 105 is configured for measuring the received signal strength of the user device 110 and comparing the value of received signal strength of the user device 110 with pre-defined threshold signal strength value, wherein pre-defined threshold signal strength value is pre-recorded in the facilitator device 105. If the value of the received signal strength is greater than the pre-defined threshold signal strength value, then the facilitator device 105 establishes a connection with the user device 110.

[0042] In some other implementations, the facilitator device 105 lists one or more nearby user devices thereby enabling the merchant to select one of the user devices for completing the transaction. That is, once the facilitator device 105 broadcasts its presence, the one or more user devices which are in close proximity (signal strength is greater than threshold) to the facilitator device 105 write a handshake signal thereby enabling the merchant to select one of the user devices. Upon selection by the merchant, a connection is established between the facilitator device and the user device for completing the payment and hence the transaction. At step 320, the user device 110 fetches the payload for the transaction from the facilitator device 105 and communicates the payload for the transaction to the authentication server 115 via the communication network 120, wherein the payload for the transaction comprises encrypted payment information. It has to be noted that, once the connection is established, the user device 110 may fetch the payload for the transaction from anywhere within the Bluetooth range of the facilitator device 105.

[0043] At step 325, the user device 110 completes the transaction upon successful authentication by the authentication server 115. In one embodiment of the present disclosure, upon receiving the payload for the transaction, the authentication server 115 decrypts the payload for the transaction to determine the payment information, wherein the payment information comprises facilitator device information such as facilitator device ID and at least an amount owed by the user. Further, the authentication server 115 authenticates the payload for transaction as described in paragraph [0028] and communicates the result to the user device 110, wherein the result comprises at least one of an amount owed (amount to be paid by the user), breakup amount, the facilitator device ID, merchant information and the like. Hence, the user may verify the result and complete the transaction by making necessary payments through any known methods such as credit/debit cards, online banking, stored value cards, payment wallets, and the like. In preferred embodiment, the amount is credited to the merchant account number, i.e., account number associated with the facilitator device 105 and a status of the transaction is communicated to the facilitator device 105 which in turn notifies the merchant about the status by turning on one or more LEDs from the LED module 240 or though textual display or any audio-visual alerts or combination thereof.

[0044] In one embodiment of the present disclosure, the platform provides a payment wallet using which the user may make the payment to complete the transaction. Further, the merchant may install a merchant application (linked with the facilitator device) in his smartphone or any other such devices for verifying the transaction, for balance enquiry or for any such financial transactions.

[0045] Figure 4 illustrates an exemplary user interface of the payment application enabling the user to establish a connection between the user device 110 and the facilitator device 105 in accordance with an embodiment of the present disclosure. When the user launches the payment application and clicks on "connect" option 405, the payment application searches for nearby facilitator device that is broadcasting the presence of payment service profile and measures the value of the signal strength of the received Bluetooth signal. If the value of the signal strength of the received Bluetooth signal is greater than the pre-defined threshold signal strength, then payment application establishes the connection between the user device 110 and the facilitator device 105. Further, the payment application displays "pay bill" option 410 enabling the user to accept reception of payload for the transaction. Once the user click on "pay bill" option 410, the payment application fetches the payload for the transaction from the facilitator device 105 and communicates the same to the authentication server 115.

[0046] Figure 5 illustrates an exemplary user interface of the user device presenting result of authentication in accordance with an embodiment of the present disclosure. As described, upon successful authentication, the authentication server 115 communicates the result and the result is displayed on the user device 110 for further verification by the user. As shown, the result window 505 displays at least the facilitator device ID, merchant name and bill mount (amount owed by the user). Further, the user interface provides "confirm" option 510 and "cancel" option 510. Clicking on "confirm" option 510, the payment application navigates the user to payment page where the user may select one of the payment method such as wallet payment, credit/debit card, online payment, etc., for completing the transaction. On the other hand, the user may cancel the transaction by clicking on the "cancel" option 515 in cases where there is a mismatch in the amount owed by the user or if the user wishes to terminate the transaction.

[0047] Hence, the system and method to complete the transaction disclosed in the present disclosure does not require a reliable internet connection at the POS terminal. Hence, the system is cost effective and merchants involved in small businesses may deploy the facilitator device with minimal cost compared to traditional POS terminal.

[0048] Further, the facilitator device and the user device exchange data over Bluetooth low energy technology and hence the system does not require NFC chip or any other such communication interface for completing the transaction.

[0049] While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person skilled in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.

[0050] The figures and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. For example, orders of processes described herein may be changed and are not limited to the manner described herein. Moreover, the actions of any flow diagram need not be implemented in the order shown; nor do all of the acts necessarily need to be performed. Also, those acts that are not dependent on other acts may be performed in parallel with the other acts. The scope of embodiments is by no means limited by these specific examples. Numerous variations, whether explicitly given in the specification or not, such as differences in structure, dimension, and use of material, are possible. The scope of embodiments is at least as broad as given by the following claims.
