Patent ID: 7773940

Claim:
A method for data transmission between a write/read station of a radio frequency identification system and at least one external functional unit arranged at any point in a communication connection between the write/read station and an antenna, the communication connection being configured as a cable connection, the method comprising the steps of: (a) sending at least one data block from the write/read station to the at least one external functional unit for receipt by the at least one external functional unit, wherein the at least one external functional unit receives commands with the same coding and the same type of modulation that the commands have when the commands are sent to a transponder; and (b) following reception of the transmitted at least one data block, evaluating the at least one data block by the at least one external functional unit; wherein transmission of the at least one data block takes place exclusively by way of a radio frequency identification communication connection with a cable from the write/read station to the at least one external functional unit or from the at least one external functional unit to the write/read station.
