Abstract: A method for receiving a signal during an intrabody communication via a user carrying a terminal. The method is performed by the terminal and includes: receiving a signal from a communication device, indicating that the user moved closer to the device between two instants; detecting, in the signal received, a first radio frame generated between the two instants, the first frame being at the same frequency as that of the signal received; detecting, in the signal received, a second radio frame generated between the two instants, the second frame being at a different frequency to that of the signal received; comparing the first frame to the second frame; and validating a transaction based on the presence or absence of information common to the first and second compared frames.
