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. The ATR conveys information about the communication parameters proposed . Given a Smart Card ATR (Answer-To-Reset); Is is possible to determine which bytes that can be variable to create an ATR Mask for the particular card? An example ATR might look like (which can be parsed by Ludovic Rousseau's ATR parser ):

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 .Smart cards generally work using a set of commands, sent from the application to the card in a block known as an APDU (Application Protocol Data Unit), and which the card will respond to with an APDU response. The reader (nfc phone in this case) talks to smart cards using ISO 7816 (T=CL) APDU exchange, which is transported via contactless interface ISO 14443-4. Since there is ISO 7816 in this case, you will get ATR. In python, you can use the pyscard library to interact with smart cards, there is an example that should help you display the ATR at http://pyscard.sourceforge.net/pyscard-framework.html#framework-samples

Get the ATR from the smart card. Iterate through entries in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais\SmartCards registry key and do the following: Apply ATRMask subkey value that is stored in the registry to the ATR that was acquired from the smart card. The basic demo is very simple, it can show you how to list the readers in the system, connect/disconnect it, get the card's ATR, and transmit one APDU with a card. Note: The basic demo only accepts one APDU without any non-number chars, such as: "0084000008" (get an 8-bytes challenge from the 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.You can either type the new ATR in the New ATR field and click OK or Apply to activate the changes, or use the ATRs found on the inserted card. They are displayed on the Inserted Card's ATR box. You can find the new ATR value in the smart card product literature.
