Let me correct one point : if ATR(TD1) is present (i.e. set to 1) which means T=0 is the default protocol (not T=1). Please refer section 8.2.3 of same specification (ISO/IEC 7816-3) i.e. If . 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 .If a connection has previously established using the specified protocol, this method returns the same Card object as the previous call. Parameters: protocol - the protocol to use ("T=0", . This Java sample code describes the Java Smart Card I/O API used to get access to a common smart card. It demonstrates the communication with smart cards using APDUs .

This library allows you to transmit and receive application protocol data units (APDUs) specified by ISO/IEC 7816-3 to a smart card. This java library is built on top of the WinSCard native .

Communication between the reader and card is usually based on either of two link protocols, the byte-oriented T=0, or the block-oriented T=1. Alternative protocols referred to as . While the focus of this guide is the software, hardware, and tools necessary to work with various types of smartcards, the guide is geared for those wanting to interact with .

Smart Card Reader T0 T1 communication on APDU level

This specification describes the Java Smart Card I/O API defined by JSR 268. It defines a Java API for communication with Smart Cards using ISO/IEC 7816-4 APDUs. It thereby allows Java .If a connection has previously established using the specified protocol, this method returns the same Card object as the previous call. Parameters: protocol - the protocol to use ("T=0", .

Java Card technology is the leading open, interoperable platform that enables smart cards and other resource-constrained devices to securely run Java technology-based applications.Let me correct one point : if ATR(TD1) is present (i.e. set to 1) which means T=0 is the default protocol (not T=1). Please refer section 8.2.3 of same specification (ISO/IEC 7816-3) i.e. If TD1, TD2 and so on are present, the encoded types T (type of protocol) shall be in ascending numerical order. 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.

T=1 just doesn't use GET RESPONSE at all, so there is no reason for Python to handle it automatically. Important: note that Java Card also handles the GET RESPONSE automatically, so you should never have to implement it explicitly.If a connection has previously established using the specified protocol, this method returns the same Card object as the previous call. Parameters: protocol - the protocol to use ("T=0", "T=1", or "T=CL"), or "*" to connect using any available protocol. This Java sample code describes the Java Smart Card I/O API used to get access to a common smart card. It demonstrates the communication with smart cards using APDUs specified in ISO/IEC 7816-4. It thereby allows Java applications to interact with applications running on the smart card.This library allows you to transmit and receive application protocol data units (APDUs) specified by ISO/IEC 7816-3 to a smart card. This java library is built on top of the WinSCard native library that comes with the operating system (or libpcsclite1 installed on Linux), which in turn communicates to the myriad USB smart card readers .

Communication between the reader and card is usually based on either of two link protocols, the byte-oriented T=0, or the block-oriented T=1. Alternative protocols referred to as T=USB and T=RF may be used. The JCRE APDU class hides some of the protocol details from the application, but not all of them, because the T=0 protocol is rather .

T=1 is not a byte oriented protocol such as T=0. For T=1 and indeed T=CL the datalink layer determines the size of the command and response APDU, not the application layer with the Nc and Ne bytes. Share

It defines a Java API for communication with Smart Cards using ISO/IEC 7816-4 APDUs. It thereby allows Java applications to interact with applications running on the Smart Card, to store and retrieve data on the card, etc. The API is defined by classes in the package .Let me correct one point : if ATR(TD1) is present (i.e. set to 1) which means T=0 is the default protocol (not T=1).
