Topic: What kind of tag I am having here?

Hi,

I just got a new tag witch I can not define.

nfc-list:

Connected to NFC reader: NXP / PN533 - PN533 v2.7 (0x07)
1 ISO14443A passive target(s) was found:
    ATQA (SENS_RES): 00  04
       UID (NFCID1): xx xx xx xx
      SAK (SEL_RES): 00

0 Felica (212 kbps) passive target(s) was found.

0 Felica (424 kbps) passive target(s) was found.

0 ISO14443B passive target(s) was found.

I guess it is a MIFARE Ultralight but if I tried mfultralight but for sue ATQA != 0x44:

Connected to NFC reader: NXP / PN533 - PN533 v2.7 (0x07)
ERROR: tag is not a MIFARE Ultralight card

I also compiled now the latest 1.5.1 libnfc.
But also if I skip ATQA != 44 it can't read the tag. Also I try to modify the Classic tag detection SAK != 0x08 but it also can'T handle the tag.

Please help!
