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.

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. 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.
What are APDUs
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. An APDU is an Application Protocol Data Unit, a TPDU a Transport Protocol Data Unit. 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 ).
Application Protocol Data Unit (APDU) is a standardized data format and communication protocol used in the interaction between smart cards - in our case, NFC tags - and card readers or host systems.
The T0 and TDi characters contain bit maps which indicate the presence or otherwise of the following TAi, TBi, TCi, and TDi bytes. The TA1, TB1, TC1, and TB2 characters are referred to as the global interface bytes and are fundamental to the operation of the card.
type of protocol supported by the card. This is achieved by the ATR issued by the MCU and one of two possible protocols will be provided: T0: the data on the I/O line will be arranged byte by byte. T1: the data on the I/O line will be arranged by packet of bytes. The ATR also gives a bunch of information necessary to read/write 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. Protocol T=0 is the asynchronous half-duplex character transmission protocol; whereas T=1 is the asynchronous half-duplex block transmission protocol. The T0 protocol is a byte-oriented protocol where a character is transmitted across the channel between the reader (MMUART) and the card.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.
