Mifare Classic answering to RATS

To whom it may concern,

 

I have an issue with several MiFARE classic cards. According to MIFARE ISO/IEC 14443 PICC Selection, on page 9, a MiFARE classic tag should not answer to RATS command, which is confirmed by its datasheet. I am sure thes tags are MiFARE Classic because they are vulnerable to specific attacks.

 

What can i conclude ?

- Is this document not up to date and/or not enough all-inclusive ?

- Is these cards smart MX or MIFARE PLUS SL1 (and then SAK is wrong) ?

- Is raw frame for RATS the same as a proprietary MiFARE Classic command ?

 

Thank for your future answers,
