Claim 8:
9. A device configured to receive a near-field radio wave using electromagnetic-wave conduction capacities of the body of a user, the user able to make a validation gesture that modifies characteristics of the radio wave, the radio wave comprising frames the device comprising a detection circuit, a processor, and a memory coupled to the processor, the memory containing instructions that are intended to be executed by the processor in order to:
detect a first modification of a characteristic of the radio wave, the first modification being resultant from a start of the gesture;
detect a second modification of a characteristic of the radio wave, the second modification being resultant from an end of the gesture, the acquisition of a right for the user being dependent on the detections of the first and second modifications, a lifetime of the right being directly linked to a duration of the validation gesture;
extract, from a frame of the radio wave, a random factor time-variable verification code allowing a timestamp to be deduced; and,
send, to a server that manages the right, a detection message relating to at least one detection, wherein the detection message comprises the random factor time-variable verification code, allowing a timestamp to be deduced.
