AP
Host Interface
The host interface of the AP controls the NFC chip. The NFC chip passes through the matching network
and connects to the NFC antenna on the battery cover through the Pogo pin.
The NFC chip can realize the card simulation function. The UICC card with encryption function can also
realize the card simulation function by communicating with the NFC chip through the SWP interface.
