I have just discovered the reader that expects T0 communication even if the card ATR returns T1. Q: What is the logic must be to determine what protocol to use? And if there is a spec behind it, can you please point me out to it. All EMV-compliant smart cards must support the T=0 or T=1 protocols, while terminals must support both.

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. T=0 is a byte based protocol while T=1 uses frames underneath. Most cards with T=0 don't support extended length. Note that to get extended length functionality that the javacardx.apdu.ExtendedLength tagging interface needs to be implemented. JCOP cards can be configured to use T=0/T=1/T=CL and others.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.

This is one of the major issues with ISO 7816. The procedure byte is part of the T=0 transmission protocol. It is not defined in the application protocol, although it may map to SW1, the first part of a status word. It is only send to indicate to .In the context of smart cards, an application protocol data unit (APDU) is the communication unit between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816 -4 Organization, security and commands for interchange . If the card is able to process more than one protocol type and if one of those protocol types is indicated as T=0, then the protocol type T=0 shall indicated in TD1 as the first offered protocol, and is assumed if no PTS is performed.

At the current time there are two communication protocols that are in general use, T=0 asynchronous half duplex character transmission. T=1 asynchronous half duplex block transmission. The T = 0 protocol is the predominant protocol in France and was the only protocol specified in ISO 7816 - 3.The ISO 7816 standard defines the necessary protocols to communicate with a smart card. Although the communication software is tested with TimeCOS, the basic communication protocol (ISO 7816, T = 0) implemented in this application note is common with all smart cards. 2012 Freescale Semiconductor, Inc.

The most commonly used ones are T0 and T1. T0 is designed for smaller data transfers where as T1 is designed for bulk data transfers. Both provide asynchronous half duplex communication. Application : Smart cards are generally used for portable data storage and retrieval.I have just discovered the reader that expects T0 communication even if the card ATR returns T1.
