Is it possible to read the originality signature from a PN532?

[lexicus]

Hello

Is it possible to read the originality signature from a Mifare Ultralight AES card using ESP32 and PN532 reader (using Adafruit_PN532 library)

I can see in the user manual of PN532 a limited list of commands:

0x60 / 0x61 Authentication A / Authentication B
0x30 16 bytes reading
0xA0 16 bytes writing
0xA2 4 bytes writing
0xC1 Incrementation
0xC0 Decrementation
0xB0 Transfer
0xC2 Restore

Is there another way to read it? Or is there another compatible reader I can try?

Thank you!

Hi @lexicus,

Please help me looking into the MIFARE Ultralight AES Datasheet, chapter 8.9 (Product originality), where you can find how to read the originality signature:

"The originality signature can be read with the READ_SIG command."

The same way, you can find the command table and commands description in chapter 9.1 (MIFARE Ultralight AES Command Overview) and chapter 10.7 (READ_SIG) respectively.

I hope you find this helpful!

Best regards,
Julián.
