A significant difference between the reader and tag antenna dimensions result in bad communication and energy harvesting performance because of the small coupling factor. As smartphone NFC antennas can have .
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 .

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.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 .
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). ATR is for contact cards and is specified in ISO 7816. For contacless cards, it is the PC/SC reader (IFD) that generates the ATR. The ATR is constructed based on: ATS (Answer to Select) for ISO 14443 Type A cards. ATQB and ATTRIB bytes for ISO 14443 Type B cards.
For contactless cards, its equivalent is called ATQ, and it comes in two variations: ATQ-A and ATQ-B, for each of the two ISO14443 types. So the way I'd recommend to go is: The reader sends both REQ-A and REQ-B, polling to see if there are contactless cards in range.
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 .A card lodges a data message in its memory upon power up. Layout of this message conforms with ISO/IEC 7816 and can be retrieved by a card reader (sReaderState.cbAtr). The ATR message contains information on proposed card communication parameters, card’s manufacturer or issuer, application selection options, country code and more.
chapter about ATR for further information on how the Answer to Reset (ATR) is generated for contactless smart cards. The Diagnostic Tool has an internal flat database that allows a quick lookup of the ATR. The smart card DDI allows callers to the NFC device driver to perform low level smart card operations on NFC contactless smart cards. This includes listening on card arrival/departure notifications, reading meta-data of the smart card like ATR, UID and Historical Bytes information as well as performing read/write operations on the specific NFC .
