Information security is a relevant issue in the modern world. One solution to this problem could be storing files on a flash drive. Digital data is protected mechanically: only those who know the secret combination of gear placement can open such a flash drive. This cipher is difficult to describe in words, it can only be memorized visually. For ease of memorization, the elements of the cipher are designed in the form of sides of light. Idea by Stas Tatarinov. Design by Mikhail Chistyakov. Exclusive right: LLC 111. Attention! Each product has an original instruction with a cipher. Please do not mix up the boxes with instructions when extracting multiple flash drives simultaneously. Read speed not less than 27 MB/s, write speed not less than 12 MB/s. The flash drive is packaged in a kraft cardboard tube.
