Credit Card ID Protection
More About Credit Card Protecting Sleeves
Credit Card Sleeves, which are sold under names like "Secure Card" are essentially Faraday Cages, but they have an important purpose, which involves making sure that people do not steal your credit card numbers. These attractive sleeves prevent RFID, or radio frequency tags, from disclosing your credit card information to scanners without your consent.
