The Tatonka Card Holder RFID B protects credit and bank cards against data theft because the built-in CRYPTALLOY® film blocks the radio waves of all commercial frequencies used for data readout.The pocket offers space for at least four cards in credit card format. It is folded up and closed with an elastic band.

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.
