Abstract: The invention relates to a method and a system for radio identification with an additional close-range check, which prevent misuse of a radio identification system and increase the security of radio identification. In particular, so-called relay attacks are to be largely prevented in passive entry systems. The method according to the invention firstly provides for activation of a transponder (S1) for reading of its data. After this step, an additional close-range status signal is provided (S2) which indicates the close range of a reader. Once the close-range status signal has been detected by a transponder (S3), data transmission for reading of the data stored in the transponder by the reader is possibly enabled in reaction to the detection of the close-range status signal (S4) and the data can be read by the reader for identification of the transponder (S5).

Abstract: It is proposed that passive wireless transponder systems used in the context of procedures for access identification be provided with signaling that can be perceived by human beings. This also makes it possible to detect that a relay attack, which is difficult to prevent, is being carried out. Attention is also drawn to other types of manipulative interference with the communication and to certain problems with the high-frequency transmission. By the employment of comparatively inexpensive and highly reliable means, this near-simultaneous perception of an identifying process for access purposes produces a very effective reduction in such threats to the security of the system. Other simple measures may have an advantageous effect in connection therewith. The signaling may also assist an ergonomic process. For example, an automobile entry or access system that is not specifically actuated, referred to as a passive keyless entry system, may be improved.
