Method for transmitting data between a read/write device and a data memory, use of the method in an identification system and a read/write device and mobile data memory for an identification system

A device comprising:

• a read/write unit operable to transmit data;
• and
• at least one mobile data store operable to receive the transmitted data from said read/write unit and transmit a response,
• wherein a plurality of successive time slots are provided, each time slot representing a respective amount of time and at least one response sequence from one of the at least one mobile data store is transmitted within at least two successive evaluation timeslots, each evaluation timeslot corresponding to a respective one of the plurality of timeslots, and wherein further, each response sequence comprises at least one identification timeslot and a data-store identifier, and the identification timeslot comprises an identifier for evaluating the data-store identifier for a corresponding mobile data store at least from a subsequent timeslot onward.

A method for transmitting data between a read/write unit and a high-speed data store, the method comprising:

• providing a frame corresponding to an amount of time, the frame comprising a plurality of subframes, wherein each subframe comprises a plurality of successive timeslots;
• designating at least one timeslot in the read/write unit as a high-speed evaluation timeslot;
• cyclically transmitting a high-speed response sequence from the high-speed data store, wherein the high-speed response sequence comprises at least a high-speed identification timeslot operable to identify the high-speed sequence as originating from a high-speed data store, and a high-speed data store identifier block comprising an identification number operable to identify the high-speed data store from which the high-speed response sequence was transmitted;
• identifying, during one of the at least one high-speed evaluation timeslots, the high-speed identification timeslot transmitted from the read/write unit;
• and
• identifying the high-speed data store from which the high-speed response sequence was transmitted at least during a timeslot immediately subsequent to a transient timeslot, wherein the transient timeslot is immediately subsequent to the high-speed identification timeslot.
