This is the command nfc-relay-picc that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
nfc-relay-picc - Relay demonstration tool for ISO14443-4
SYNOPSIS
nfc-relay-picc
DESCRIPTION
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.
tag <---> initiator (relay) <---> target (relay) <---> original reader
OPTIONS
-h
Help
List options
-q
Quiet mode
Suppress printing of relayed data (improves timing)
-t
Target mode only (to be used on reader side)
Commands are sent to file descriptor 4
Responses are read from file descriptor 3
-i
Initiator mode only (to be used on tag side)
Commands are read from file descriptor 3
Responses are sent to file descriptor 4
-n N
Adds a waiting time of N seconds (integer) in the loop
EXAMPLES
Basic usage:
nfc-relay-picc
Remote relay over TCP/IP:
socat
TCP-LISTEN:port,reuseaddr
"EXEC:nfc-relay-picc -i,fdin=3,fdout=4"
socat
TCP:remotehost:port
"EXEC:nfc-relay-picc -t,fdin=3,fdout=4"
NOTES
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.
