SMART CARD READER

摘要

The invention concerns a smart card reader (10) comprising a central unit (20) including means (MP2, MEM2, PG20, 23) for transmitting and receiving on a communication bus (60) binary messages in a first format determined by a communication protocol for contact smart cards, a card receiving device (40) including a card connector (42) connected to the central unit (20) via the communication bus (60), and a read head (30) for contactless smart card (53) comprising a serial interface (31). The invention is characterised in that the serial interface (31) of the contactless card read head (30) is directly connected to at least a data wire (I/O) of the communication bus, and the contactless read head (30) is designed by hardware and/or software not to reply to a command for activating a contact smart card and to reply to a specific activation command (ACTIV) different from a contact smart card activation command.
