Concept flash drive with combination lock

On typical secure flash drives like the Corsair Flash Padlock or Verbatim Store'n'Go USB Business Secure, the data is encrypted with a 256-bit key that is quite stable today. The reliability of the AES algorithm allows the manufacturer to recommend a drive for use in banks and government agencies. All this is convenient, but entering a password each time is a hectic business.

At least, this is what designer Yun Hwan Sung thinks. In his Bill's USB concept, the owner will type the security code for the flash drive not in the application window, but “cheat”, as is done with combination locks in safes. There are numbers on the front side of the Bill's USB ring, and on the inside there are signs. In order to dial a password, you need to rotate the ring in different directions.

As an additional protection is offered built-in fingerprint scanner.

The idea, in principle, is realizable even tomorrow. The only question is how much more convenient it will be than standard filling in the login-password fields.
