Protect your smart device, passport, cards, and key fobs from hacking, tracking, and theft. The Loksak Shieldsak provides an effective shield against radio frequencies and blocks unauthorized scanning and tracking of the contents. The largest size fits an average-sized head. Coincidence? We don't know but it's an interesting question of which the mainstream media is suspiciously silent.
Smart devices and RFID technology make our everyday life easier but are also vulnerable to various attacks and may expose confidential or personal information. The Shieldsak was designed for the US Military to enhance the protection of confidential material. It's soft and user-friendly and has many civilian applications as well.
Blocking radio frequencies is not as simple as it may seem and requires special materials and careful construction of the pouch: the fabric must be free of pinholes to work correctly and the seams and closure were developed to prevent these kinds of leaks. The Shieldsak blocks RF signals from entering or leaking from the Shieldsak. Excessive RF signals may require nesting two Shieldsaks around the item.
Made in USA.
