Abstract
The invention concerns a communication device (20) forming an interface between an electrically coupled reader (10), in particular with contact, and at least a radioelectrically coupled contactless device (30). The interface (20) comprises electronic coupling pads (24), in particular resistive contact pads, with corresponding coupling elements of the reader (10), and transmitting and/or receiving means for electromagnetic waves (26), in particular an antenna, designed to enable communication with the contactless electronic device (20). The interface (20) comprises in particular means (28) for managing data transfer between the contacts (24) and the antenna (26) so as to enable communication between the electrically coupled reader (10), requiring the insertion of a device with electrically coupled contacts, and the contactless electronic device (30). Preferably, the device (30) is arranged in a portable object capable of being fixed on part of the bearer, in particular a watch.
