Passport sleeve with RFID read-out protection

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

Additional information:

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.

As the manufacturer ‘Kryptonic Technologies’ has confirmed the required processing of the foil in all of Tatonka’s RIFD products. 

  • Best RFID scan protection with TÜV certified RFID blocking material CRYPTALLOY®

T-Square Rip FD

Fabric 2:




Composition 100% Polyamid

Thanks to the fine structure, this development by Tatonka is extremely technical. The very tight, special weaving method of the 210 den fibres makes the fabric extremely strong, but it remains light at the same time. By using FD yarn (full-dull) the fabric gets a dull surface. Perfect for our lightweight trekking and hiking rucksacks.


Composition Aluminiumlegierung

Screening products with the specially developed tear-resistant material CRYPTALLOY® offer the highest level of protection against RFID/NFC attacks. The TÜV certified material blocks radio waves on all the usual RFID frequencies and can be used for all cards.
