Abstract
The present disclosure is directed to a system and method for wirelessly communicating Radio Frequency (RF) signals. In some implementations, a microSD payment system includes an antenna element and a card element. The antenna element affixes to a surface of a mobile device and includes antenna for wireless communicating RF signals with retail terminals and a connection to a microSD card element. The card element includes a shape and dimensions approximately equal to a standard microSD card and wirelessly executes transactions with the retail terminals using the antenna of the antenna element.
Claims7
A micro SecureDigital (microSD) payment card, comprising:
- a first interface that connects to a microSD slot of a mobile host device;
- a second interface that includes an antenna for wirelessly communicating with retail terminals;
- secure memory that stores user credentials and a payment application used to execute financial transactions with the retail terminals, the user credentials and the payment application associated with a financial institution;
- one or more processors configured to:
- communicate through a Graphical User Interface (GUI) of the mobile host device;
- determine an attempted transaction using the microSD payment card is potentially fraudulent activity;
- in response to the potentially fraudulent activity, automatically deactivate, while the microSD payment card is connected to the mobile host device, the second interface based, at least in part, on a deactivate command;
- and
- transmit, through the first interface, a command to the financial institution to temporarily deactivate a financial account associated with the user credentials, wherein the command is transmit to the financial institution using cellular technology of the mobile host device.
A method, comprising:
- interfacing a microSD slot of a mobile host device;
- wirelessly communicating with a retail terminal;
- storing user credentials and a payment application used to execute financial transactions with the retail terminals, the user credentials and the payment application associated with a financial institution;
- communicating information through a Graphical User Interface (GUI) of the mobile host device;
- executing the payment application using the user credentials in response to at least a transaction request received by the RF module;
- transmitting at least one transaction response to the retail terminal based, at least in part, on the executed payment application;
- determining an attempted transaction using the microSD payment card is potentially fraudulent activity;
- in response to the potentially fraudulent activity, automatically deactivating, while interfacing the mobile host device, wireless communication based, at least in part, on a deactivate command;
- and
- transmitting, using cellular technology of the mobile host device, a command to the financial institution to temporarily deactivate a financial account associated with the user credentials.
