5.3.3.1. ATR for contactless storage user tokens
The ATR of the user token is composed as described in the table below. In order to allow the
application to identify the storage card properly, it‘s Standard and Card name describing bytes
must be interpreted according to the Part 3 Supplemental Document, maintained by PC/SC.
Tokens using technology like MIFARE are examples of such user tokens.
