Abstract

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.
