smart card protocol t 0 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.

Unlike RFID (Radio Frequency Identification) tags, NFC tags have the capability to both send and receive information, allowing for two-way communication. In contrast, RFID tags are typically designed for one-way communication. .
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. –Created in 2005. According to its abstract, it specifies the operating conditions of an integrated circuit card that provides a USB interface. An integrated circuit card with a USB interface is named USB-ICC. ISO/IEC 7816-12:2005 specifies: • the electrical conditions when a USB-ICC is operated by an interface device - for those contact .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. – 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).
ISO/IEC 7816-12:2005 provides two protocols for control transfers. 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). 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.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.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.
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.The specifications permit two transmission protocols: character protocol (T=0) or block protocol (T=1). A card may support either but not both. (Note: Some card manufacturers adhere to neither of these protocols.
