This foldable card holder protects up to four credit or key cards from unauthorised 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.
Material
210 denier HD Nylon full-dull Eco
Composition: 100% Polyamide
The lightweight, PFC/PFAS-free finished polyamide fabric with yarn thickness 210 denier is waterproof due to triple PU coating. The FD yarn used gives the material a matte surface. It is used, for example, in hiking backpacks.
CRYPTALLOY®
Screening products with the specially developed tear-resistant material CRYPTALLOY® offer the highest level of protection against RFID/NFC attacks.
T-Rain Rip
The high-tear and abrasion-resistant RipStop fabric shows a lively surface due to the irregularly interwoven thicker threads.

This is the second one we have brought - this one for my wife. These are so great and secure to pop in your pocket, and thye hold alot of cards. Have had a couple of cheaper ones so did an experiment one day at a number of shops where we brouhgt stuff. With our card in the cheaper RFID wallets payment would go through when you touched the terminal - so much for being RFID. That certainly doesent happen with this Tatonka holder. If you want an RFID holder that does what it says it will do, get one. As they say - you get what you pay for.
