nfc-relay-picc - Relay demonstration tool for ISO14443-4
This tool requires two NFC devices. One device (configured as target) will
emulate an ISO/IEC 14443-4 type A tag, while the second device (configured as
initiator) will act as a reader. The genuine tag can be placed on the second
device (initiator) and the tag emulator (target) can be placed close to the
original reader. All communication is now relayed and shown in the screen on
tag <---> initiator (relay) <---> target (relay) <---> original reader
Suppress printing of relayed data (improves timing)
Target mode only (to be used on reader side)
Commands are sent to file descriptor 4
Responses are read from file descriptor 3
Initiator mode only (to be used on tag side)
Commands are read from file descriptor 3
Responses are sent to file descriptor 4
Adds a waiting time of N seconds (integer) in the loop
Remote relay over TCP/IP:
There are some differences with nfc-relay:
This example only works with PN532 because it relies on
its internal handling of ISO14443-4 specificities.
Thanks to this internal handling & injection of WTX frames,
this example works on readers very strict on timing.
