Abstract

A RFID jamming device and methodology are provided for inhibiting unwanted intrusions of RFID smart tag technology. The device includes a mechanism for actively or passively preventing a RFID scanner from accurately receiving information from smart tags associated with products.

Claims (5)

1. A jamming device for inhibiting unwanted intrusions of RFID smart tag technology, said device comprising means for inhibiting smart chip RFID scanners from accurately receiving information from smart tags associated with products, wherein said inhibiting means comprises a passive device, and wherein said passive device comprises a structure containing a sufficient number of RFID chips so as to overwhelm a RFID scanner with simultaneous RFID signals to an extent that the scanner cannot process such signals.

2. The device as in claim 1 , wherein said structure comprises at least about 1,000 RFID chips.

3. The device as in claim 1 , wherein said structure comprises at least about 10,000 RFID chips.

4. The device as in claim 1 , wherein said structure is disguised as a consumer electronic device.

5. The device as in claim 1 , wherein said structure is of a size so as to fit within one of a pocket, purse, briefcase, and backpack.
