Description

TITLE OF THE INVENTION:

A system and a method for payment and instant refund using a biometric digital wallet

DESCRIPTION OF INVENTION

FIELD OF INVENTION

The present invention is generally related to the field of biometric software technology;

Specifically, the present invention relates to a biometric payment and instant refund system.

BACKGROUND OF THE INVENTION

Entire world has become more connected than ever with the help of recent communication technologies. The connections have affected daily lives of people that have changed our habits. One of the most significant changes is our payment behavior, where payments shift from cash to digital money. This shift offers new benefits to corporations because the digital payment solutions have become more global. Therefore, the willingness to use such solutions has increased dramatically.

An electronic wallet (e-wallet), or digital wallet, is a payment system that allows an individual to make an electronic commerce transaction, such as an online purchase of items using a computing device, e.g., a mobile computing device. A server-side e-wallet is created by an organization for and about an individual consumer, and is maintained on the organization's servers. Server-side e-wallets provide security, efficiency, and added utility for the consumer. Electronic wallets include a software component and an information component. The information may include, for example, a user's shipping address, billing address, and payment information/credentials including credit card numbers, expiration dates, and security numbers. An electronic wallet may or may not include a near field communication (NFC) hardware component, which allows payment transactions to be performed by swiping or touching a mobile computing device, card, fob, or other hardware onto or in proximity to an enabled terminal.

SUBSTITUTE SHEETS (RULE 26) Digital wallet account services enable a user to electronically store payment information in a user's digital wallet account. In payment transactions involving a digital wallet account, the payment information is often stored on an application or a module of a user computing device. Often, a user must have the user computing device present when conducting in-store digital wallet transactions with a point-of-sale device because the payment information is communicated from the user computing device to the point-of-sale device. For example, the user computing device and point of sale device may establish a wireless communication channel, such as a Bluetooth, Wi-Fi, or NFC communication channel to transmit payment information from the user computing device to the point-of-sale device. However, such a process may be inconvenient to the user because the user must physically cany' a user computing device, such as a mobile phone, to conduct a digital wallet transaction, which may deter users from using digital wallet accounts. Current technology does not provide direct access to payment account information associated with a user's digital wallet account at a merchant system point of sale device interface for selection by a user for use in a transaction at the point-of- sale device.

The prior art reveals that there have been multiple attempts to develop a digital wallet and address the security and carrying the hardware component with the user. Following patent and non-patent literature describes the existing state of the art.

CN110599168A discloses a digital wallet login method and device based on a block chain, wherein the digital wallet login method based on the block chain comprises the following steps: if a digital wallet login instruction is detected, acquiring a first biological characteristic; obtaining a second biometric bound to the digital wallet; calculating a matching degree between the first biological characteristic and the second biological characteristic; and if the matching degree meets the target condition, controlling the digital wallet to be switched to a login state, wherein the digital wallet in the login state has the authority of performing authorized signature on transaction information by using a private key of the digital wallet. The embodiment of the application provides a new method for logging in the block chain digital wallet, the digital wallet can be logged in without inputting a private key, the use is convenient, and meanwhile, the safety of the digital wallet can be ensured.

SUBSTITUTE SHEETS (RULE 26) US 11195164B2 relates to systems, methods, devices, and computer readable media for enabling direct electronic payment transfers are disclosed. Identification information of a payer, based on a user selection at a mobile device, is received from a first application installed on the mobile device. A user identification of a payment amount is received via a second application installed on the mobile device. The second application is different from the first application. Biometric data of the user is captured at a biometrics reader of the mobile device, and then compared to authorized biometric data to authenticate the user. Upon successful authentication of the user, a request for the electronic payment transfer from the payer to the user for the payment amount is initiated from the mobile device.

US20150302413A1 describes an apparatus and method to conduct financial and other transactions using a wireless computing device. The wireless device includes an input display part, one or more processors, and at least one memory⁷ device. The memory device has stored therein a wallet application for completing transactions based on wireless data communications between the computing device and an external electronic device. The memory device further stores at least one electronic credential. The wireless device pennits transmission, via a near-field communication (NFC) module, of at least one electronic credential to an NFC reader of the external electronic device based on comparing a biometric characteristic of a user, detected by a biometric characteristic reader, with stored biometric information

SUBSTITUTE SHEETS (RULE 26) The following detailed description illustrates embodiments of the present disclosure and ways in which the disclosed embodiments can be implemented. Although some modes of carrying out the present disclosure have been disclosed, those skilled in the art would recognize that other embodiments for carrying out or practicing the present disclosure are also possible.

One of the most useful methods to authenticate users is to use their biometric information. Almost all systems allow users to use their biometric information in terms of hardware. Additionally, the security of biometric methods is a proven fact.

The present invention provides a system and a method for payment and instant refund using a biometric digital wallet.

According to an embodiment of the present invention, modules such as Authentication; Fingerprint Registration; Adding the Payment into digital wallet; receiving payment request; Fingerprint Matching and Transaction Summary drive the operation of the present invention.

In the Authentication module, the Registration and Login pages are there. The biometric digital wallet requires the user to register their Name, Mobile Number, Email Address and Password. The user will use their registered mobile number or email address and password to access the digital wallet.

According to further embodiment of the present invention, the user registers his/her finger prints in Bio Metric digital wallet. The user fingerprints are read and processed in byte format, encrypted, and stored in the database and in the cloud storage. In addition, an image of the fingerprint is not stored but is discarded after extraction.

According to further embodiment of the present invention, the user can add moneyusing Credit / Debit Card and can keep the amount in their digital wallet. Users must add funds to the digital wallet before undertaking any transaction. Moreover, the presently claimed invention keeps all user funds in the digital wallet.

In accordance to an embodiment of the present invention, the User can make a payment using biometric digital wallet and receive a refund on cancellation using the flight booking application.

SUBSTITUTE SHEETS (RULE 26) In accordance to an embodiment of the present invention, the User can make a payment using biometric digital wallet and receive a refund on cancellation using online shopping application.

In accordance to an embodiment of the present invention, the biometric digital wallet can be used with in-Store seller dashboard wherein two accounts are created viz., one is seller account and another one is user/buyer account. The seller generates the bill amount to buyer through Bio Metric digital wallet dashboard then the buyer can directly pay the amount using biometric fingerprint authentication and the payment will be deducted from buyer wallet and credited to seller’s wallet.

According to further embodiment of the present invention, in the Fingerprint Matching module, the Bio Metric algorithm compares and matches fingerprints.

To make any transaction possible, the Bio Metric device and the user must be in physical contact. The seller will add the bill amount to his payment dashboard, and the Bio Metric device will validate the buyer's finger print. In the case of a successfill validation, the amount deducted from the buyer's e-wallet will be transferred to the seller’s e-wallet.

After the Bio Metric validation has been successful, the data is transmitted from the device via the EIS or electronic information system and a network connection has been established for verification of e-wallet and transactions.

Most methods of establishing a connection requires electronic devices with the right programming to collect information from the device. Moreover, it requires a network connection, such as a wireless network or a telephone line.

The Bio-Metric device sends the buyer’s finger print to the digital wallet API in byte format, which will do the validation with BioAPI, then return the success or failure message back to the Bio-Metric device.

Finally, API returns the data in the JSON format with details like Failure or Success message with buyer and payment details. When everything matches the API will debit the amount automatically from the buyer wallet and transfer it to the seller wallet. The device processes each transaction within seconds based on available network speed.

SUBSTITUTE SHEETS (RULE 26) BioAPI is an application programming interface that enables web applications to access biometric fingerprint readers from most modem web browsers. With support for JavaScript access to the readers, BioAPI can be used across different browsers for extremely fast capturing and matching of fingerprint data for use in a web application. BioAPI makes it very simple to incorporate fingerprint capturing functionality in your browser-based application through JavaScript. Using Bio API eliminates the need for Java runtimes or browser plug-ins on the client machine, so there are no issues involving applet signing and deployment related to different JRE versions and browser versions. Detailed information about each transaction can be found on the transaction summary page. The Bio Metric digital wallet database maintains all the transaction information separately.

The Bio Metric digital wallet is simple to use in store. User can scan his/her fingerprint on biometric device and within seconds payment will be deducted from the user’s/buyer’s digital wallet account and deposited in the seller’s digital wallet account.
