NAME
nfc-emulate-tag - Simple tag emulation command line demonstration tool
SYNOPSIS
nfc-emulate-tag
DESCRIPTION
nfc-emulate-tag is a simple tag emulation tool that demonstrates how emulation can be done
using libnfc.
Currently, this tool partially emulates a Mifare Mini: it is detected as Mifare Mini but
internal MIFARE proprietary commands are not yet implemented.
To be able to emulate a target, there are two main parts:
- communication: handle modulation, anticollision, etc.
- computation: process commands (input) and produce results (output).
This demonstration tool proposes a logical structure to handle communication and a simple
function to deal with computation.
To improve the target capabilities, we can now implement more allowed commands in a single
function: target_io()
Please note that, due to timing issues, it is very difficult to implement an ISO14443-4
tag this way: RATS request expects a quick ATS answer. By the way, even if you implement
another kind of tag, timing issues are often the source of problems like CRC or parity
errors. The OmniKey CardMan 5321 is known to be very large on timings and is a good
choice if you want to experiment with this emulator with a tolerant reader.
IMPORTANT
ACR122 devices (like touchatag, etc.) can be used by this example (with probably timing
issue), but if something goes wrong, you will have to unplug/replug your device. This is
not a libnfc's bug, this problem is due to ACR122's internal MCU in front of NFC chip
(PN532).
