It depends on the goal. If your goal is to be able to identify that exact card type .Answer to Reset (ATR) is the response output by a Smart Card ICC conforming to ISO/IEC . It depends on the goal. If your goal is to be able to identify that exact card type in all possible variations, there is no way an ATR mask will do that for you. If you have a general card "family" you want to associate, you might try masking out the historical bytes.Answer to Reset (ATR) is the response output by a Smart Card ICC conforming to ISO/IEC 7816 standards, following electrical reset of the card’s chip by a card reader.

An Answer To Reset (ATR) is a message output by a contact Smart Card conforming to ISO/IEC 7816 standards, following electrical reset of the card's chip by a card reader. The ATR conveys information about the communication parameters proposed .When a contact smart card is inserted into a smart card reader, such as the popular ACR38, Omnikey 3121 or Cloud 2700R, the reader sends power and a reset signal to the card, and the card responds with a dozen or more bytes of data known as the Answer To Reset (ATR).
The smart card ATR value that is stored in the registry should be the expected value after the ATRMask has been applied to an ATR read from a smart card. Otherwise, the masked ATR values from the card and the registry do not match and the pairing fails. The ATR Mask tells Windows to look only at the significant parts of the ATR. In the example above, all parts are significant. The Crypto Provider and Smart Card Key Storage Provider entries should be as shown for a minidriver smart card.

A powerful tool designed to modify the Answer to Reset (ATR) of smart cards. This utility is essential for developers and researchers working with smart card technologies, allowing them to customize the ATR to suit specific requirements or troubleshoot communication issues. The ATR encodes information about the smart card, specifying everything from the card vendor, to physical characteristics such as transmission rates and electrical timings. Most of this information is used by the firmware on a card reader, but smartcard programmers typically use the ATR to determine the type of the card the reader. For example, the Gemalto .NET smart cards can have ATR=3B0000417374726964, or ATR=3B0001417374726964. From this, a mask can be configured to inform an application using the smart card which part of the ATR to compare.
ATR starts with 3B/3F, followed by T0, TAx/TBx/TCx/TDx (for x in [1..4]), up to 15 historical bytes and a single byte checksum. Depending on whether your card talks type A or type B of ISO 14443 you will get an ATS or an ATQB, which have distinct formats but both end with a two-byte checksum.
