Nokia 6112 and Mifare Ultralight

[TayfunKalkanci]

Hello,
I try to recognize RFID tags with a Nokia 6112. I have absolutely no problem with the tags Mifare 1k, but the Nokia does not seem to see the tags Mifare Ultralight.

I have a tool allowing me to write into the tag memory so I wrote it :
00 in locks (page 2) to have the read/write authorisation.
e1 10 06 00 in CC (page 3) to declare it works with NDEF data
and differents kind of NDEF message (page 4 ...) (empty NDEF 0300FE or NDEF message copied from Mifare 1k).

And the Nokia does not seem to see the tag, either in reading neither in writing.

Any Idea ??

Hallo,

our experiences with the Nokia 6212 showed that it reads most MIFARE Ultralight (64 Byte) just fine. We only had problems with some ID1 antenna sizes. We didn't have success in reading Ultralight C (192 Byte) tags though.

Hallo,

that's right. I guess my Nokia 6212 is quite old... It finally succed to read my Ultralight tags when it has about 1 minute to do so.

Thank you.
