I use st25r3916 , How do I read and write 14443a tag block? Is there a ready-made function interface

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).

Rgds
