Hi,

Do you use a X-NUCLEO-NFC06A1 board (and X-CUBE-NFC6 Firmware) or a ST25R3916-DISCO board (and STSW-ST25R010 PC software) or a custom board (and ST RFAL firmware)?

ISO14443-3 does not define any tag memory organization. Different kinds of tags are relying on ISO14443-3 :

T1 tags
T2 tags
T4 tags
proprietary tags

If you are using the ST RFAL,

see rfal_t1.c for T1 tag read/write API
see rfal_t2.c for T2 tag read/write API
see rfal_t4.c for T4 tag helpers API

Feel free to share more details about your tag (manufacturer an model).
