Abstract

Unauthorized electronic access to RFID devices embedded in credit cards, personal identification cards, and other cards is prevented by providing wallets, purses, card holders, and other card receiving devices with layers of electromagnetic shielding material which substantially surround cards having RFID devices embedded therein.

Claims

1. A method of preventing unauthorized electromagnetic access to an RFID device embedded within a card comprising the steps of:

providing at least one length of electromagnetic shielding material; and

substantially surrounding the card having the RFID device embedded therein with the length of electromagnetic shielding material.

2. An apparatus for preventing unauthorized electronic access to an RFID device embedded within a card comprising:

at least one length of electromagnetic shielding material; and

means for positioning the length of electromagnetic shielding material in a surrounding relationship with respect to the card having the RFID device embedded therein.
