Wirelessly executing financial transactions

摘要

The present disclosure is directed to a system and method for wirelessly executing financial transactions. A payment card includes an interface, a communication module, secure memory, a user-interface module, and a processing module. The interface connects to a slot of a mobile host device. The communication module wirelessly receives RF signals from and transmits RF signals to a retail terminal. The secure memory stores user credentials and a payment application used to execute financial transactions with the retail terminal. The user credentials and the payment application are associated with a financial institution. The user-interface module presents and receives information through the GUI of the mobile host device. The processing module executes the payment application using the user credentials in response to at least a transaction request received by the communication module and transmits a transaction response to the retail terminal based, at least in part, on the executed application.

主权项

1. A micro SecureDigital (microSD) payment card, comprising:
a microSD interface configured to connect to a microSD slot of a mobile host device and communicate SD commands with the mobile host device through a wired connection; a Near Field Communication (NFC) transceiver enclosed in the microSD payment card and communicably coupled to a communication module, wherein the NFC transceiver includes an NFC antenna; the communication module that wirelessly communicates RF signals with retail terminals using the NFC antenna and configured to selectively switch the NFC transceiver for the microSD payment card between an activate state and an inactivate state in response to at least an event; secure memory that stores user credentials, account information, and a payment application used to execute financial transactions with the retail terminals and a financial institution, wherein the stored user credentials are not accessible by users of the mobile host device and the payment application is issued by the financial institution and encrypts transaction information prior to transmission to the financial institution through retail terminals; a user-interface module that stores one or more pages in the secure memory, transmits, using the microSD interface, the one or more pages from the secure memory of the microSD payment card, the one or more pages displayed through a GUI of the mobile host device request information from a user of the mobile host device, and in response to the request, receives through a GUI of the mobile host device user information; and a processing module that identifies the one or more pages that has received user information, executes the payment application using the user credentials in response to at least a transaction request received by the communication module, and transmits commands to the communication module to transmit at least one transaction response to the retail terminal based, at least in part, on the executed payment application and using the user credentials and the user information.
