This foldable card holder protects up to four credit or key cards from unauthorized data scanning. A built-in CRYPTALLOY® film blocks radio waves across all common commercial frequencies used for RFID readout, helping safeguard your card information when travelling, commuting, or moving through busy public spaces.
The sleeve folds closed with an elastic strap to keep cards secure in a compact format that slips easily into a pocket or pack. A PFC/PFAS-free DWR finish adds practical water resistance for everyday use.
CRYPTALLOY® shielding has been independently tested and certified by TÜV Saarland for effectiveness across a wide frequency range (100 kHz to 4 GHz), covering low, high, and ultrahigh frequency bands used for data transmission.
