1. A device, comprising:
- an NFC controller, comprising;
a transceiver circuit configured to wirelessly receive first data from a device;
wherein the NFC controller is further configured to provide the first data, without having a direct physical signaling between the transceiver circuit and an application processor circuit, in the form of second data to the application processor circuit via a secure element, where a secure function is performed on the first data to produce the second data;
the secure element operably coupled to the NFC controller via a first interface;
the application processor circuit operably coupled to the secure element via a second interface; and
an antenna coupled to the NFC controller.
