Secure Sleeve®, Secure Badgeholder®, and Secure Wallet™ products create an RFID shield by blocking the electromagnetic energy necessary to power and communicate with contactless smart cards, passports, enhanced drivers licenses (EDLs), TWIC, PIV, CAC and transit cards. This is essential to total security because although most contactless smart card systems implement industry-standard security mechanisms, readers can be modified to access information without authorization.
