Let data pirates run into the void: Because now the sensitive data of your chip cards are protected from insidious reading! With the blocker cards in your wallet, debit and credit cards, health cards, ID cards, driver's licenses, etc. are safe from data theft.
Small, strong, practical: each card fits in any wallet and protects up to 12 cards thanks to a range of 2.5 cm. So you don't need individual sleeves or a special protective case.
