Random ID

[sunnyso]

Hi,

For NTAG424, there is a random UID function. May I know how to calculate the random UID ? as there is not mention detail calculation in documents .

I think it can generate a Random ID base on Application key.

Thanks

Sunny.

Dear Sunny So,

On the NTAG 424 DNA there is a TRGN as seen in datasheet (below pic). It offers randomness as required this comply with AIS31 please check this spec.
