Probably the easiest way to protect your cards from data theft.
Simply insert the Secure Card into the card compartment with your bank and credit cards, ID, driving licence, company card, health card, hotel key card, ... Up to 12 cards with RFID (Radio Frequency Identification) and NFC (Near Field Communication) chips are reliably protected against scanner access from the outside.
The Secure Card catches the skimming signal from a reader and interferes with it so that it cannot return to the scanner.
Even at a distance of 3cm (1.2"), nobody can read your personal data.
