This 5-pack of tropical RFIDsleeve 25 RFID-Blocking Credit Card Sleeves from Pacsafe is designed to help safeguard your personal and financial information by preventing an inserted credit or debit card with a Radio Frequency Identification (RFID) chip from being accessed by an unauthorized RFID reader.

Current credit or debit card designs now feature an RFID chip that stores the personal and financial data typically associated with any credit or debit card and allows that information to be easily accessed by a specialized radio transmitter. In a retail setting, this can help make shopping more convenient by simplifying and speeding up the check-out process. Unfortunately, identity thieves in possession of a transmitter that is capable of broadcasting and receiving an RFID signal may read and record your credit or debit card's information without your knowledge.

To prevent this type of identity theft, these RFID-blocking credit card sleeves provide a way to store and carry your credit or debit cards between purchases while preventing RFID signals from reaching them. Each of the two included sleeves is constructed from an alumina-paper composite that prevents electromagnetic radiation, including radio waves, from reaching its contents.

Each included sleeve accommodates two credit or debit cards and is tear resistant as well as water resistant.
