QN9090 and how to read the 7 byte serial number

[mtailorsw]

The QN9090 datasheet says

* Unique 7 byte serial number (cascade level 2 according to ISO/IEC 14443-3)

How can I read that value from my program as I need to give my product a unique serial number and may as well leverage this value.

I thank you in advance and look forward to hearing from you.

Kind regards
Mahendra

Hello Mahendra,

Hope you are doing well. The Unique 7 byte serial number is from the internal NTAG I2C of QN9090T/QN9030T.

For more information about the NFC tag, you can refer to section 42 of the QN9090(T)/QN9030(T) User Manual (UM11141). And also you can refer to the NTAG I2C Plus Data Sheet.

Hope this helps.

Regards,

Ricardo
