The core of the compact Secrid wallet is the aluminum Cardprotector that protects your RFID/NFC cards, such as your smartcard, against remote reading. Both your money and your privacy are protected. With a simple movement your cards come cascading out of your Secrid wallet. So even without opening your wallet, you can use your cards and find the card you are looking for at a glance. The cover of leather provides room for additional cards and coins. Bills, receipts and business cards you keep in the ultra-thin but strong wrap on the inside. The Miniwallet, Slimwallet and Twinwallet are safe and compact, but certainly not boring in their tight leather sleeves.
