Foldout sleeve with RFID reader protection for at least four credit cards, bank cards, key cards or ID cards in credit card format. Additional information: With the CRYPTALLOY® foil Tasmanian Tiger 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 Tasmanian Tiger’s RIFD products.
