Shanghai Faith Sleeve RFID Card Blocker is special designed to
shield RFID signals.
We have picked the best material after so many tests, it can block
signal effectively, hard to tear and waterproof.
Each sleeve protects one
credit card, debit card or Identification card. 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

Detailed Product Description
Aluminum foil Secure Sleeve RFID Blockers - Protect your
Credit Cards from illegal reading! These Aluminum foil 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.
