Part 4 of EN 726 specifies the application independent card related characteristics of card terminals able to process cards complying with Part 3 of EN 726. All common characteristics which are necessary for a standardized card use in the terminals are defined. This Part of the standard does not preclude letting terminals accept and process cards complying with other standards.
The application-specific characteristics are not defined in this Part of EN 726. They are defined and described in the relevant application requirements.
This Part of EN 726 does not specify any internal realisation of a card-terminal. It describes:
- the requirements for the physical and environmental specifications on the card terminal, the electronic
signals and transmission protocols;
- the application independent logical model, which should be used as a basic design of the logical structure
of card specific requirements supported by the terminal;
- the description of the application independent functions and general scenarios to be used by most of
the applications;
- the error handling.
