nfc-relay-picc \- Relay demonstration tool for ISO14443-4

.SH DESCRIPTION
|
|
|
|
|
.B nfc-relay-picc
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
real-time.

.SH EXAMPLES
|
|
|
|
|
Basic usage:
|
|
|
|
|
|
|
|
|
|
\fBnfc-relay-picc\fP
|
|
|
|
|
|
|
|
|
|
Remote relay over TCP/IP:
|
|
|
|
|
|
|
|
|
|
\fBsocat\fP
|
|
|
|
|
TCP-LISTEN:port,reuseaddr
|
|
|
|
|
"EXEC:\fBnfc-relay-picc -i\fP,fdin=3,fdout=4"
|
|
|
|
|
\fBsocat\fP
|
|
|
|
|
TCP:remotehost:port
|
|
|
|
|
"EXEC:\fBnfc-relay-picc -t\fP,fdin=3,fdout=4"
|
|
|
|
|
|
|
|
|
|
.SH NOTES
|
|
|
|
|
There are some differences with \fBnfc-relay\fP:
|
|
|
|
|
|
|
|
|
|
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.
