Abstract: The exemplary embodiments of the invention realize an efficient prevention of massive infiltration of cloned RFID transponders into existing and new RFID systems. Furthermore, reader devices used for authentication of RFID transponders do not need to be on-line and do not need to be equipped with a Security Authentication Module (SAM). This simplifies authentication procedures and reduces costs. According to an exemplary embodiment of the invention a transponder-specific originality signature is stored by a transponder manufacturer on the transponder. The transponder-specific originality signature may, for example, be stored in the non-volatile memory (EEPROM) of the transponder during the fabrication of the transponder. This transponder-specific originality signature can be checked at any time in a convenient way, which provides an indication of originality of said transponder.

Abstract: In one embodiment, a communication apparatus is provided. The apparatus includes a near field communication circuit designed to update at least one event field, associated with a number of occurrences of at least one event, which converted from a first data coding format to a second data coding format and provided in an external communication message that is communicated automatically or in response to receiving an access command. Also included in the instant specification are communication systems, and methods of communicating.
