Abstract
The invention relates to a chip card reader (10) comprising a central processing unit (20) comprising means (MP2, MEM2, PG20, 23) for emitting and receiving, on a communication bus (60), binary messages with a first format determined by a communication protocol for contact chip card, a card receiving device (40) comprising a contact card connector (42) connected to the central processing unit (20) by means of the communication bus (60), and a read head (30) for contactless chip card (53) comprising a serial interface (31). According to the invention, the serial interface (31) of the contactless read head (30) is directly connected at least to a data wire (I/O) of the communication bus, and the contactless read head (30) is arranged in a hardware and/or software way so that it does not respond to a contact chip card activation command and responds to a specific activation command (ACTIV) different from a contact chip card activation command.
