A protective shield for your data. Secure your documents, payment cards, even your car key with a discreet but very effective card that blocks NFC and RFID signals. The chip embedded in the card disrupts the operation of scanning devices, making it impossible to read sensitive data or steal money. One additional card in your wallet will protect all the others! It works within a radius of 5 cm, so you can breathe a sigh of relief - the entire wallet is properly looked after, regardless of whether you are in a store, supermarket, or on the tram. Works anytime and anywhere, requires no additional energy source. Perpetuum mobile for your safety.
