Plastic cards have a hard time, they get bent and become brittle in your pocket. In particular, RFID/NFC cards are not safely stored in a regular wallet. RFID (Radio Frequency Identification) or NFC (Near Field Communication) cards have a chip and an antenna for wireless communication. These cards, such as the public transportation pass, new credit cards and admission tickets, can be activated, selected and copied from up to many metres away, without you noticing. The Secrid Cardprotector works as a firewall in your wallet.
To safely use an RFID/NFC card, you slide it out 3 cm from the Cardprotector; the sensitivity for the radio signal is then substantially reduced, but still sufficient for contact over short distances. By minimising the time duration and signal strength, you remain outside the reach of digital pickpockets.
