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.
