Detachable electronic device e.g. combi-chip, for e.g. portable telephone, has control unit transmitting activation signal based on detection of activation data for passing selection unit from one selection position to another position

摘要

The device has a selection unit (134) selecting an access mode via a communication interface (12A) or a communication interface (11A), for communicating data to application units. A control unit (15) detects an activation data issued from a portable telephone (16), and transmits an activation signal to the applicative units based on the detection, for passing the unit (134) from one selection position to another selection position. One of the selection positions relates to a contactless access mode and the other position relates to a contact access mode.
