System and method for providing data to a merchant device from a user device over a wireless link

A method comprising:

• establishing, from a user device, a communication between the user device and a merchant device via a wireless link between the user device and the merchant device, the communication being associated with a potential purchase;
• presenting, on a display of the user device, an instruction associated with the potential purchase;
• receiving, in response to the instruction, a single-interaction from a user of the user device to confirm a payment for the potential purchase, the single-interaction comprising a security measure to prevent unauthorized purchases;
• retrieving, based on the single-interaction from the user, user payment data from a memory of the user device;
• and
• transmitting, from the user device to the merchant device and via the wireless link, the user payment data to make a purchase, wherein transmitting the user payment data via the wireless link to the separate device to make the purchase is performed according to a protocol for communicating the user payment data to the separate device.

A merchant device comprising:

• a processor;
• and
• a computer-readable memory device storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
• establishing a communication between the merchant device and a user device via a wireless link between the user device and the merchant device, the communication being associated with a potential purchase and being initiated in connection with the potential purchase,
• wherein, based on the communication, the user device can present, on a display of the user device, information associated with the potential purchase;
• and
• receiving, at the merchant device and via the wireless link, user payment data to make a purchase, wherein the user payment data is obtained based on (1) the user device receiving a single-interaction from a user in response to the information to confirm a payment for the potential purchase, the single-interaction comprising a security measure to prevent unauthorized purchases and (2) the user device retrieving, based on the single-interaction from the user, the user payment data from a memory of the user device, wherein receiving the user payment data via the wireless link at the merchant device to make a purchase is performed according to a protocol for communicating the user payment data to the merchant device.
