A radio-frequency communication device includes connection means electrically connecting an integrated circuit component, or intended for this purpose; and selection means for selecting an electromagnetic current power supply for the component. The device includes an alternative power supply source for powering the component during the reception of an electromagnetic field as soon as the electromagnetic power supply current received by the component is insufficient.

Radio-frequency communication device comprising a power supply of assisted radio-frequency origin

The invention relates to an integrated circuit comprising at least one microprocessor [linked to at least one non-volatile memory [that can be accessed by sectors. The integrated circuit comprises a detector [for discovering when a threshold number of bad sectors has been exceeded in said non-volatile memory [

Detector of abnormal destruction of memory sectors

In a radiofrequency network, such as a Bluetooth network, two devices are securely identified to one another for a communication session. One of the devices is designated as a master apparatus, and the other is a slave apparatus. An automatic identification process is carried out by placing the two devices in close proximity with one another, and transmitting very short range signals from the master apparatus, to be exclusively received by the slave apparatus. If the two devices are able to communicate over this short range, an identification key is generated and passed to the slave apparatus for subsequent exchanges in normal, larger range communications.
