    摘要: Reader (420) for determining the validity of a connection to a transponder (440), designed to measure a response time of a transponder (440) and to authenticate the transponder (440) in two separate steps. Transponder (440) for determining the validity of a connection to a reader (420), wherein the transponder (440) is designed to provide information for response time measurement to said reader (420) and to provide information for authentication to said reader (420) in two separate steps, wherein at least a part of data used for the authentication is included in a communication message transmitted between the reader (420) and the transponder (440) during the measuring of the response time.

    摘要: An antenna (1) for communication with a multitude of transponders (6a . . . 6c) is provided, the antenna (1) having an antenna conductor (2) which completely encloses at least one read/write region (4c) intended for a transponder (6c) individually and/or, when a multitude of read/write regions (4a, 4b) are arranged within a continuous inner region (3) enclosed by the antenna conductor (2), the inner region (3) has constrictions (5a) between the read/write regions (4a, 4b) so that the antenna conductor (2) largely encloses these read/write regions (4a, 4b) individually. The electromagnetic field radiated by the antenna (1) is thereby concentrated on the read/write regions (4a . . . 4c).
