La Funda bloqueadora RFID KÄRN mide 6,3 × 9,1 cm y está pensada para una tarjeta: la bancaria contactless, el DNI electrónico, la de transporte o la de acceso al trabajo.
Mientras la tarjeta está completamente dentro, la funda ayuda a bloquear lecturas RFID/NFC no autorizadas. Para pagar o identificarte, la sacas y la usas como siempre.
Es una forma sencilla de añadir protección RFID a la cartera o el tarjetero que ya tienes. Si quieres proteger también el DNI, el Pack 2 Fundas bloqueadoras RFID incluye dos.
