SYNOPSIS

DESCRIPTION

11     nfc-emulate-forum-tag2 is a demonstration tool that emulates a NFC-Forum
12     Tag Type 2 with NDEF content.
13
14     Some devices compliant with NFC-Forum Tag Type 2 can be used with this
15     example, in read mode only.
16

IMPORTANT

18     This example has been developed using PN533 USB hardware as target and
19     Google Nexus S phone as initiator.
20
21     This is know to NOT work with Nokia 6212 Classic and could fail with sev‐
22     eral NFC Forum compliant devices due to the following reasons:
23
24     - The emulated target has only a 4-byte UID while most devices assume a
25     Tag Type 2 has always a 7-byte UID (as a real Mifare Ultralight tag);
26
27     - The chip is emulating an ISO/IEC 14443-3 tag, without any hardware
28     helper.  If the initiator have too strict timeouts for software-based em‐
29     ulation (which is usually the case), this example will fail.  This is not
30     a bug and we can't do anything using this hardware (PN531/PN533).
31
32     ACR122 devices (like touchatag, etc.) can be used by this example, but if
33     something goes wrong, you will have to unplug/replug your device.  This
34     is not a libnfc's bug, this problem is due to ACR122's internal MCU in
35     front of NFC chip (PN532).
