* @file nfc-emulate-uid.c
* @brief This example can be used to emulate a tag which which have a "really" custom UID
*
* NFC devices are able to emulate passive tags but manufacters restricts the
* customization of UID. With PN53x, UID is only 4 bytes long and the first
* byte of emulated UID is hardwarely set to 0x08. This example show how to
* emulate a full customized UID by "manually" replying to anticollision
* process sent by the initiator.
*
* @note Unfortunately, this example can't directly start in fully customisable
* target mode. Just after launching this example, you will have to unlock an
* hardware situation by sending a RATS (Request for Answer To Select) command.
* To do this, you can use a second NFC device (placed in target's field) and
* launch nfc-list or nfc-anticol. After this first step, you now have a NFC
* device (configured as target) that really emulate custom UID. You could view
* it using the second NFC device with nfc-list.
* NFC devices are able to emulate passive tags but manufacturers restrict the
* customization of UID. With PN53x, UID is only 4-byte long and the first
* byte of emulated UID is hard-wired to 0x08 which is the standard way to say
* this is a random UID. This example shows how to emulate a fully customized
* UID by "manually" replying to anti-collision process sent by the initiator.
