11 nfc-emulate-forum-tag2 is a demonstration tool that emulates a NFC-Forum
12 Tag Type 2 with NDEF content.
13 Some devices compliant with NFC-Forum Tag Type 2 can be used with this
15 example, in read mode only.
16
18 This example has been developed using PN533 USB hardware as target and
19 Google Nexus S phone as initiator.
20 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 - 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 - 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 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).
