Abstract: The invention concerns a method and a device for radiofrequency (RF) communication. According to the method, a communication can be set up between a reader (12) and an RF device (10) at least over a medium distance and over a short distance. The short distance communication is set up using an RF-ID transponder (20) and an antenna (16). In order to set up the medium distance communication, the reader (12) sends a command signal to the RF-ID transponder (20) in order to power up at least one microcontroller (24) and a transceiver (34). The microcontroller (24) sends to the reader (12), via the transceiver (34), a reply message comprising at least the identification of the device (10).
