Patent ID: 7786846

Claim:
A communication station for contactless communication with a plurality of transponders, the communication station comprising: inventorizing command generation means to initiate an inventorizing operation to uniquely identify at least one transponder of the plurality of transponders, wherein the inventorizing operation corresponds to control information which includes an inventorizing command data block (IVTDB) comprising: a memory area selection data block (DSELDB) which identifies a selectable address data memory area of at least two selectable address data memory areas on an addressable memory on the at least one transponder; wherein a first address data memory area of the at least two selectable address data memory areas corresponds to a unique identification data block (UIDDATA) which is assigned by a manufacturer of the at least one transponder and uniquely identifies the at least one transponder; and wherein a second address data memory area of the at least two selectable address data memory areas corresponds to a typical user data block (USERDATA) that is different from the unique identification data block and which is assigned by a user of the at least one transponder and uniquely identifies the at least one transponder; modulation means coupled to the inventorizing command generation means, the modulation means to provide a modulation output in connection with the control information; and transmission means coupled to the modulation means, the transmission means to transmit a signal in connection with the modulation output.
