Tyvek Secure Sleeve RFID Blockers - Protect your Credit Cards

Protect your cards!

These Tyvek card holders are designed to shield RFID signals.  Each sleeve protects one credit card, debit card or Identification card. About 100 million credit cards now have "contactless" technology embedded into them. RFID (Radio Frequency Identification) chips in a credit card emit the account number, expiration date and other information. Secure sleeves create an RFID shield by blocking the electromagnetic energy necessary to power and communicate with contactless smart cards.

Illegal RFID credit card readers can access your name, credit account number and expiration date from  RFID enabled credit cards. These readers can be concealed by electronic pickpockets so that someone could walk through a crowded area and steal nearby credit card information without the card holder ever knowing it happened.
