  • Patent number: 10460317
    Abstract: Conducting hands-free transactions comprises a server at a payment processing system, a user computing device, and a merchant computing device. The payment processing system registers a merchant system as a hands-free payment participant and provides a beacon identifier. The payment processing system receives a communication from a hands-free payment application on a user computing device, the communication comprising a transaction token, an identification of a user account, and the beacon identifier received by the user computing device via a wireless communication from a device associated with the merchant system and transmits the transaction token to the merchant system computing device.

  • Publication number: 20160012430
    Abstract: A payment processing system receives a token from a user device. Based on the first token, the payment processing system establishes a second token that remains valid longer than the first token. The payment processing system then associates the second token with a user account identifier and establishes a rescue code for use in an offline user transactions. The payment processing system then communicates the second token and the rescue code to the user device. When the user engages in an offline transaction, the payment processing system receives the rescue code and the user account identifier from the merchant computing device. Based on the user account identifier received from the merchant computing devices, the payment processing system identifies the second token and verifies that the received rescue code matches the rescue code associated with the user account identifier. Based on the verification, the payment processing system authorizes the sales transaction.
