Keep your personal data secure. The blocker card gives data thieves no chance. Do you carry a bank card with contactless payment capability in your wallet or a passport with an e-passport chip? Be cautious. With NFC apps on smartphones, data thieves can read your card information. RFID chips receive a radio signal and respond on the same frequency. The Aplic blocker card takes advantage of this and responds with a jamming signal. Within a few centimeters, reading other cards becomes impossible. This way, the card protects your entire wallet.
