Abstract
This IC card reader (1) is intended to release the software workload of a smart IC card (2) which itself supervises the running of its transaction. It is managed by a circuit (14) with microcontroller (140) and memory (141) and includes display means (11). It contains in memory (141) a library of programs which define visual, audio or other objects that are displayed on the display means and are executed by its circuit (14) with microcontroller (140) and memory (141) in response to a call from the connected IC card (2). By virtue of this library of programs, the IC card reader (1) provides a connected IC card (2) with a particularly sophisticated man-machine interface accessible using simplified commands. The object program calls are advantageously accompanied by parameters allowing the way in which the objects are defined and animated to be adjusted at leisure.
