Abstract:
An NFC device includes first and second secure elements, an NFC router, and a processor. A method involves emulating, by the NFC router in response to a command from the processing device, an RF card emulation transaction. The RF card emulation transaction includes transmitting by the NFC router a command to the first and second secure elements to verify the presence of NFC transaction applications in the first and second secure elements. The method also includes receiving, by the NFC router, responses from the first and second secure elements and a new RF message from an NFC terminal. The responses indicate the NFC transaction applications stored by the first and second secure elements, and the new RF message relates to an NFC transaction. The new RF message is routed to the first or second secure element based on the responses.
