    Hello Dennis,

    Yes, the basic principle is to verify the signature of the tag UID using a public key.

    Here is a link to a technical article, which provides an overview of the digital signature verification process : TA0358

    For specific implementation details on the ST25TA02KB product, please request the AN5101 document to your ST local sales.

    Best regards,

    TQ

    ​Hello,

    First of all, thanks for your interest in ST25 products !

    For your information, the TruST25 digital signature is not a feature available  on ST25TA64K product.

    If you are interested in this feature, It is available on ST25TA02KB, ST25TA512B, ST25TV512 and ST25TV02K.
