Tatonka uses CRYPTALLOY foil in all its RFID-blocking products. This foil provides maximum shielding across all relevant RFID frequency ranges (from 100 kHz to 4 GHz, covering low, high, and ultra-high frequencies). It also disrupts radio communication through frequency shifting. The effectiveness of the CRYPTALLOY foil has been tested and certified by TÜV Saarland.
The manufacturer of the foil, Kryptronic Technologies Munich, has confirmed and certified that Tatonka processes the foil according to required standards in all RFID-block products.
