STORITE Aluminum Card Sleeves RFID Credit Debit Card Protector Sleeve 1 Card Holder  (Set of 10, Silver)

RFID (radio frequency identification) is a common feature in all manner of contactless payment and keyless entry systems. Cards which use RFID feature a signal tag capable of being picked up by an electronic reader for quick transactions and keyless entry. There is a downside however: In the india and elsewhere, without a blocker present, criminals with access to a reader and encryption tool can read a card, extract the information, take control of your personal data - and even skim your bank account. These sleeves put a barrier between your cards and any card and permit readers out there. It stops criminals in their tracks; offering you just what's needed to keep your data shielded and secure.
