t 0 protocol smart card All EMV-compliant smart cards must support the T=0 or T=1 protocols, while terminals must support both. Immediately after a card is inserted into a terminal and while all contacts are maintained in a "low" state, supply voltage is applied to the card's V CC contact. I am writing an NFC tag reader application in C++, using the CR95HF .

The DS8007 and Smart Card Interface Fundamentals
To have a T=0 or T=1 communication, both the card and the reader must support it. Most of nowaday cards support only T=1 and most of readers support both protocol. – All EMV-compliant smart cards must support the T=0 or T=1 protocols, while .To have a T=0 or T=1 communication, both the card and the reader must support it.

All EMV-compliant smart cards must support the T=0 or T=1 protocols, while terminals must support both. Immediately after a card is inserted into a terminal and while all contacts are maintained in a "low" state, supply voltage is applied to the card's V CC contact.This is to support the protocol T=0 (version A) or to use the transfer on APDU level (version B). ISO/IEC 7816-12:2005 provides the state diagrams for the USB-ICC for each of the transfers (bulk transfers, control transfers version A and version B).
how rfid tag works
If an APDU command response pair has been defined for T=0 and it has both command data and response data (case 4S) then a separate TPDU will be generated to send and receive data (GET RESPONSE). See chapter 12.2.1 of ISO/IEC 7816-3 (2006).The T=0 transmission protocol was first used in France during the initial development of smart cards, and it was also the first internationally standardized smart card protocol. It was generated in the early years of smart card technology, and it is thus designed for minimum memory usage and maximum simplicity.
The SERCOM USART features an ISO/IEC 7816-compatible operating mode. This mode permits interfacing with smart cards and Security Access Modules (SAM) communicating through an ISO 7816 link. Both T=0 and T=1 protocols defined by the ISO 7816 specification are supported.ISO 7816-3: Electronic Signals and Transmission Protocols, 1989; defines the voltage and current requirements for the electrical contacts as defined in part 2 and asynchronous half-duplex character transmission protocol (T=0).Exchange Information: Exchange information with the card based on T=0 (half-duplex transmission of characters) or T=1 (half-duplex transmission of blocks) protocol. Deactivation: Deactivate the smart card.
For this type of command, using the T=0 protocol, the initial command results in a response that indicates more data is waiting (in the card). The Get Response command is then used to retrieve that waiting data.T=0 is a transmission protocol commonly used by smart cards that was first used in France during the initial development of smart cards, and it was also the first internationally standardized smart card protocol.To have a T=0 or T=1 communication, both the card and the reader must support it.
