Method for validating a transaction during a radio communication

A terminal having capabilities for intra-body communication via a user carrying said terminal, said terminal comprising:

• a processor that is configured so as to:
• receive a signal from a communication device, the signal characterizing that an approach gesture performed by the user toward the device has been performed between first and second time instants,
• from the received signal, detect the time interval, between the first and second time instants, in which an amplitude of the signal is at a maximum,
• from the received signal, detect, in the time interval, information determining whether or not the user has touched the device between the first and second time instants,
• validate a transaction depending on a value of said detected information,
• wherein the information determining whether or not the user has touched the communication device consists of binary information of a single bit length, wherein a first value of said single bit determines that the user has touched the communication device, and a second value of said single bit determines that the user has not touched the communication device.

A non-transitory computer-readable information medium comprising instructions of a computer program stored thereon, which when executed by a processor of a terminal, configure the terminal to perform a method for receiving a signal during an intra-body communication via a user carrying the terminal, wherein the method comprises:

• receiving the signal from a communication device, the signal characterizing that an approach gesture performed by the user toward the device has been performed between first and second time instants;
• from the received signal, detecting a time interval, between the first and second time instants, in which an amplitude of the signal is at a maximum;
• from the received signal, detecting, in the time interval, information determining whether or not the user has touched the device between the first and second time instants;
• and
• validating a transaction depending on a value of said detected information,
• wherein the information determining whether or not the user has touched the communication device consists of binary information of a single bit length, wherein a first value of said single bit determines that the user has touched the communication device, and a second value of said single bit determines that the user has not touched the communication device.
