Passport sleeve with RFID read-out protection. The integrated CRYPTALLOY® layer blocks radio waves and prevents unwanted read-out of data from your ID.

With the CRYPTALLOY® foil Tatonka uses a film that offers maximum shielding against relevant frequencies (from 100 kHz to 4 GHz; this means low, high and ultrahigh frequency range) and due to a frequency shift disturbs any radio communication. This was tested and certified by the TÜV Saarland.
