Understanding the Mobile World

The intertwining of telecom, banking, and M2M/IoT produces a new degree of complexity. We hope our COMPRION glossary helps you to get a good overview of all the connected terms, technologies, and concepts.


There are two standardized data exchange protocols defined in ISO/IEC 7816-3 for the communication between a smart card and a terminal: the byte-oriented half-duplex transmission protocol T=0 and the block-oriented half-duplex protocol T=1. The character-oriented T=0 protocol is very simple constructed and has a low memory capacity (about 300 bytes). The block-oriented T=1 protocol is a half-duplex protocol and works with error detection at the end of block. The memory requirement is about 1.100 bytes. The smart card and the terminal exchange data with the help of these protocols.
