       nfc-relay - Relay attack command line tool based on libnfc




       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.
