1 Scope
This part mainly:
——specifies the symbolic coding technique used by the contactless communication and defines the different logicals according to the symbols and their sequences, and also defines the Type A and Type B respectively according to bit encoding of PCD→PICC and PICC→PCD communication;
——specifies the data frame format used by Type A and Type B. The data bits are transmitted between PCD and PICC as the frame type;
——specifies the Composition mode of Type A and Type B data frames, frame size, frame time sequence, etc.;
——specifies valid command format of PCD in polling, collision detection and PICC activation;
——specifies contents of Type A and Type B PICC at initialization, polling, collision detection and state machine;
——specifies PCD processing flow at the initialization, poll and collision detection of PICC as well as its activation and shifting out.
The half-duplex block transmission protocol defined in this part is applicable to Type A and Type B and it is used to transmit information (C-APDU and R-APDU) defined by the application layer. The requirements for application layer are not defined in this part.
This part is applicable to the financial contactless integrated circuit card issued or received by the banks. The using objects are mainly the relevant departments for such card design, manufacture, management, issuance and acceptance and those for the development, integration and maintenance of the application system.
