The present invention is directed to a system for reading at least one
object having a programmable RFID device embedded therein. The object is
disposed in a predetermined reading region. The system includes a reader
loop disposed in the predetermined reading region. The reader loop is
configured to transmit a reader interrogation signal to the at least one
object disposed in the predetermined reading region and receive an RFID
signal from the at least one object in response to the reader
interrogation signal. A jamming device is disposed proximate the reader
loop. The jamming device is configured to generate a jamming signal that
prevents an external reader device disposed outside the predetermined
reading region from interrogating the at least one object disposed in the
predetermined reading area.
