NAME

       nfc-emulate-forum-tag2 — NFC Forum tag type 2 emulation command line demonstration tool

SYNOPSIS

       nfc-emulate-forum-tag2

DESCRIPTION

       nfc-emulate-forum-tag2 is a demonstration tool that emulates a NFC-Forum Tag Type 2 with NDEF content.

       Some devices compliant with NFC-Forum Tag Type 2 can be used with this example, in read mode only.

IMPORTANT

       This example has been developed using PN533 USB hardware as target and Google Nexus S phone as initiator.

       This  is know to NOT work with Nokia 6212 Classic and could fail with several NFC Forum compliant devices
       due to the following reasons:

       - The emulated target has only a 4-byte UID while most devices assume a Tag Type 2 has  always  a  7-byte
       UID (as a real Mifare Ultralight tag);

       -  The  chip is emulating an ISO/IEC 14443-3 tag, without any hardware helper.  If the initiator have too
       strict timeouts for software-based emulation (which is usually the case), this example will  fail.   This
       is not a bug and we can't do anything using this hardware (PN531/PN533).

       ACR122  devices (like touchatag, etc.) can be used by this example, 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).
