The computer decodes the public user data and the private user data from the matrix code, and decrypts one or both of the public user data and the private user data. A latch is included which can secure the control bar in either a secured position or in a release position. The outer pads are positioned in the receiving portion of the holder. A rotor 3 is fixed onto a rotating shaft 2 disposed rotatably in a housing 1, and a stator core 5 is disposed opposite to the rotor 3.
