DEVICE AND METHOD FOR THE TRAINING AND IDENTIFICATION OF CONTACTLESS CARDS BY MEANS OF CHARACTERISATION BY RADIOFREQUENCY

The device and method for the training and identification of contactless cards by means of characterisation by radiofrequency comprises a support (1) for positioning the card, whereon the card to be identified is placed; a radiofrequency signal transmitter (2) which sends the signal and the resulting electromagnetic field towards the support (1); a reconfigurable scattering element (4) which, together with the card, scatters the electromagnetic field; a receiver element (3) which picks up the field scattered by the card; and a controller (5) which gives the order to send the radiofrequency signal to the transmitter (2), reconfigures the scattering element (4), receives the signal picked up by the receiver element (3) and carries out the classification of the card, accomplishing a unique identification associated with each card, thereby preventing attacks aimed at attempting to supplant the card's identity.
