Anti-theft, RFID-blocking sleeves from Savisto: Multipack of 20 individual card holders that act as a Faraday cage; preventing contactless bank cards from being covertly scanned and skimmed by criminals.
Helps prevent theft, fraud, data loss, and privacy breaches: RFID tags are a data transmission feature in many types of bank and identification cards. Thieves can access this information with a scanner, but these sleeves provide a protective security barrier to stop the RFID chip signal.
