|
.Sh DESCRIPTION
|
|
|
|
|
.Nm
|
|
|
|
|
is a demonstration tool that emulates a NFC-Forum Tag Type 2 with NDEF content.
|
|
|
|
|
.Pp
|
|
|
|
|
Some devices compliant with NFC-Forum Tag Type 2 can be used with this example,
|
|
|
|
|
in read mode only.
|
|
|
|
|
.Sh IMPORTANT
|
|
|
|
|
This example has been developed using PN533 USB hardware as target and Google
|
|
|
|
|
Nexus S phone as initiator.
|
|
|
|
|
.Pp
|
|
|
|
|
This is know to NOT work with Nokia 6212 Classic and could fail with several
|
|
|
|
|
NFC Forum compliant devices due to the following reasons:
|
|
|
|
|
.Pp
|
|
|
|
|
- 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);
|
|
|
|
|
.Pp
|
|
|
|
|
- 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).
|
|
|
|
|
.Pp
|
|
|
|
|
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
|
|
|
|
|
.Em libnfc's
|
|
|
|
|
bug, this problem is due to ACR122's internal MCU in front of NFC chip (PN532).
