RFID disruption device and related methods
First Claim
1. A radio frequency identification (RFID) signal disruptor device to prevent data transfer between a nearby RFID interrogation device and one or more RFID data storage devices when the RFID signal disruptor device is positioned adjacent the one or more RFID data storage devices interrogated therewith, the RFID signal disruptor device comprising a container, and an RFID signal disruptor circuit positioned to be associated with the container and configured to disrupt an attempted read of a separate RFID data storage device by the RFID interrogation device when the separate RFID data storage device is positioned adjacent the RFID signal disruptor circuit, the RFID signal disruptor device operatively receiving power needed to operate the RFID signal disruptor circuit from an interrogation signal emanating from the RFID interrogation device during the attempted read of the separate RFID data storage device when inductively coupled with the separate RFID data storage device, the RFID signal disruptor circuit being positioned to generate an oscillating disruptive signal during the attempted read by the interrogation signal, thereby to disrupt the one or more RFID data storage devices from communicating with the RFID interrogation device.

Abstract
Devices and methods of disrupting data transfer between an RFID interrogation device (50, 50′) and an RFID data storage device (30, 30′) to be protected, are provided. An example of an embodiment of an RFID signal disruptor device includes a container (41, 141) and an RFID signal disruptor circuit (151, 161, 161′, 171, 171′, 271, 271′) configured to substantially disrupt the signal provided by the RFID interrogation device (50, 50′) when the RFID signal disruptor device is positioned to protect the RFID data storage device (30, 30′). The RFID signal disruptor device can also include an interrogation indicator (63, 296) configured to indicate to a user of the RFID data storage device (30, 30′) that an unauthorized RFID interrogation device (50, 50′) is attempting to interrogate the RFID data storage device (30, 30′) when the RFID signal disruptor device is positioned in close proximity to the RFID data storage device (30, 30′) to provide protection thereto and when the RFID interrogation device (50, 50′) is producing the interrogation signal.

10. A method of enhancing protection against unauthorized interrogation of one or more RFID data storage devices, the method comprising:
-
positioning a separate RFID signal disrupter device adjacent one or more separate RFID data storage devices, the RFID disruptor device including an RFID signal disruptor circuit being positioned to generate an oscillating disruptive signal during an attempted read by an interrogation signal, thereby to disrupt the one or more RFID data storage devices from communicating with the RFID interrogation device; inductively coupling the separate RFID signal disrupter device with the one or more separate RFID data storage devices during an attempted read by an RFID interrogation device; receiving portions or more of an incoming signal from an RFID interrogation device directed to the one or more separate RFID data storage devices; and generating a signal to disrupt the attempted read by the RFID interrogation device. - View Dependent Claims (11, 12, 13)
