First Claim
Patent Images
1. An apparatus comprising:
- a decoy circuit capable of detecting wireless interrogation signals transmitted to a contactless portable consumer device, wherein the decoy circuit is configured to prevent one or more interrogation devices from interrogating an authentic circuit in the contactless portable consumer device wherein the decoy circuit is present in a decoy device that is separate from, but is to be used adjacent to the contactless portable consumer device.

Abstract
An apparatus and method is provided to prevent contactless portable electronic consumer devices such as an RF identification device (RFID), tokens, mini-cards, key fobs, cellular phones, smart card, etc. from being wirelessly interrogated. In one embodiment, a decoy circuit capable of detecting wireless interrogation signals transmitted to a contactless portable consumer device is used to prevent one or more interrogation devices from interrogating an authentic circuit in the contactless portable consumer device.

10. A method comprising:
-
detecting a wireless interrogation signal from an interrogation device using a decoy circuit; responding to the wireless interrogation signal with the decoy circuit, wherein the response from the decoy circuit is more rapid than a response from a corresponding authentic circuit in a contactless portable consumer device; and providing decoy data to the interrogation device in response using the decoy circuit to deceive the interrogation device into believing that the interrogation device is communicating with the authentic circuit in the contactless portable consumer device. - View Dependent Claims (11, 12, 13)

14. A system comprising:
-
a contactless portable consumer device comprising authentic data; and a decoy device comprising decoy data, wherein the decoy device is adapted to provide the decoy data to an interrogation device before or instead of the authentic data to deceive the interrogation device into believing that the interrogation device is communicating with the authentic circuit in the contactless portable consumer device. - View Dependent Claims (15, 16, 17, 24, 25, 26, 27)

18. A method comprising:
-
obtaining a contactless portable consumer device and a decoy device; placing the contactless portable consumer device adjacent to the decoy device; receiving an interrogation signal at the contactless portable consumer device and at the decoy device from an interrogation device; and sending decoy data from the decoy device to the interrogation device to deceive the interrogation device into believing that the interrogation device is communicating with the authentic circuit in the contactless portable consumer device. - View Dependent Claims (19, 21)

20. A method comprising:
-
obtaining a contactless portable consumer device and a decoy device; placing the contactless portable consumer device adjacent to the decoy device; receiving an interrogation signal at the contactless portable consumer device and at the decoy device from an interrogation device; and sending decoy data from the decoy device to the interrogation device; and sending authentic data to the interrogation device after the decoy data is sent from the decoy device. - View Dependent Claims (22, 23)
