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. |

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 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 so as to allow mutual inductive coupling therebetween, 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 mutually inductively coupled with the separate RFID data storage device, the RFID signal disruptor circuit being positioned to generate quickly 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. |
