  • Publication number: 20230360020
    Abstract: In a case where a user terminal such as a smartphone having a plurality of IC card applications performs payment processing using communication data of UWB communication or the like other than NFC communication with a payment device such as a ticket gate or a store terminal, the user terminal selects an IC card application corresponding to the payment device used for the payment processing. The user terminal receives data from the payment device such as a ticket gate or a store terminal, performs search processing as to whether or not the own device has a specific communication scheme-compatible IC card application capable of processing communication data according to a specific communication scheme such as UWB communication on the basis of the received data, acquires an identifier (AID) of the detected application, and transmits the acquired identifier to the payment device.

  • Publication number: 20220300943
    Abstract: The present disclosure provides a configuration that enables reliable payment processing while preventing fraudulent processing even in a case where a shop terminal does not have a function to communicate with a payment server. In a payment processing system including a shop terminal and a user terminal that perform a data write process and a data read process on a data- rewritable dynamic tag, and a payment server that performs communication with the user terminal, the shop terminal writes payment data including a settlement amount and a random number into the dynamic tag. The user terminal transmits the payment data recorded in the dynamic tag to the payment server, the payment server generates a signature and transmits the signature to the user terminal after the payment processing, and the user terminal writes the signature into the dynamic tag.
