Hama Protective cover for Perso, EC card etc. against data theft by radio, set of 2

For protection against unauthorized reading of personal and biometric data. Suitable for ID cards, contactless debit, credit, access, and key cards with RFID chips. The RFID/NFC chip cannot be read when it is inside the protective sleeve. Cryptalloy® is a specially developed alloy for RFID protection. The shielding properties of Cryptalloy® far exceed those of conventional materials like aluminum; its functions are continuously tested in laboratory conditions. Consumer notice: With the spread of wireless identification (RFID), data theft has become significantly easier. Instead of physically obtaining the card to illegally copy or use it, RFID allows for information to be read contactlessly from distances of up to several meters using relatively simple means. In RFID, the chip is not visibly embedded in the card like magnetic stripes or chip cards and is read contactlessly via radio waves. The protective sleeve significantly dampens these radio waves through a special Cryptalloy film. Additionally, the protective sleeve prevents the RFID chip in ePass, ePerso, etc., from generating a magnetic field at all.
