1. An apparatus comprising:
- a portable consumer device comprising a first antenna;
an envelope coupled to and surrounding the portable consumer device; and
an insert disposed in the envelope, the insert comprising an RF shield, the RF shield comprising an electrically conductive, non-ferromagnetic material, wherein the RF shield is configured to prevent unauthorized transfer of financial data between a second antenna external to the portable consumer device and the first antenna, wherein the RF shield is separate from the portable consumer device and only one side of the portable consumer device is shielded by the RF shield.

Abstract
An apparatus and method is provided to shield contactless portable electronic consumer devices such as radio frequency identification devices (RFID), tokens, mini-cards, key fobs, cellular phones, smartcards, etc. from wireless interrogation. In one embodiment, a contactless portable consumer device which includes a first antenna is shielded from unauthorized wireless interrogation with a radio frequency (RF) shield. The RF shield includes electrically conductive, non-ferromagnetic material and is configured to prevent unauthorized data transfer between a second antenna external to the portable consumer device and the first antenna.
