nfc-relay is a utility that demonstrates a relay attack.
This tool requires two NFC devices. One device (configured as target) will emulate an ISO/IEC 14443 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 real-time.
This tool has the same issues regarding timing as nfc-emulate-uid has, therefore we advise you to try it against e.g. an OmniKey CardMan 5321 reader.
