Tatonka Card Holder Rfid B

Foldable insert cover for credit cards with RFIDreadout protection: Tatonka Card Holder RFID B
"The Tatonka Card Holder RFID B protects credit and bank cards from data theft, because the built-in CRYPTALLOYu00ae film blocks the radio waves of all commercial frequencies used for data readout. The card slot offers space for at least four credit card-sized cards. It is folded up and closed with an elastic band. The slip-in sleeve is made from partially recycled material and is PFC/PFAS-freeu00fcstet."
Additional information:
Tatonka uses a CRYPTALLOY® film in all its RFID block products. This offers maximum shielding in all relevant RFID frequency ranges (from 100 kHz to 4 GHz, i.e. low frequency range, high frequency range and ultra-high frequency range). The protective film also interferes with "radio traffic" by shifting the frequency. The functionality of the CRYPTALLOY® film has been tested and certified by TÜV Saarland. The manufacturer of the film, Kryptonics Technologies Munich, has confirmed and certified the prescribed processing of the film in all RFID-Block products to Tatonka.
