ABSTRACT:
A method and apparatus for simultaneously storing a set of read/write or respond-to-order transponders located in a container. The method transmits radiation to read/write trnsponders to energize them, receives identity data transmitted by the transponders, verifies that the identity data are not subject to dispersion, transmits a data group to the transponders, and stores the data group in memories of the transponders. If the identity data are subject to dispersion, the method interrupts radiation transmission in order to deactivate the transponders and then retransmits the radiation until the data are not subject to dispersion so that the data group can be transmitted to the transponders for storage in their memories. In the case of respond-to-order transponders, a signal is also transmitted. If the identity data are subject to dispersion, the signal is retransmitted until the data are not subject to dispersion, and then the data group is transmitted to the transponders and stored in their memories. A second data group can be stored in the transponders without disturbing the first data group stored.
