NAME

6       nfc-relay - Relay attack command line tool based on libnfc
7

SYNOPSIS

9       nfc-relay
10

DESCRIPTION

12       nfc-relay is a utility that demonstrates a relay attack.
13
14       This  tool  requires two NFC devices. One device (configured as target)
15       will emulate an ISO/IEC 14443 type A tag, while the second device (con‐
16       figured  as  initiator)  will  act  as a reader. The genuine tag can be
17       placed on the second device (initiator) and the tag  emulator  (target)
18       can  be  placed  close to the original reader. All communication is now
19       relayed and shown in the screen on real-time.
20
21       This tool has the same issues regarding timing as nfc-emulate-uid  has,
22       therefore  we advise you to try it against e.g. an OmniKey CardMan 5321
23       reader.
