Mouse coin Detector _ Reveal Society

Don't think that the mouse can only be used to move the cursor on the computer screen, it can be useful! Spanish engineers at the University of Lelida have modified their own mouse to scan the front and back of the coin through an optical mouse, and then transmit the data to a computer, and then analyze the computer program to determine the authenticity of the coin. Of course, this scanning device can also be replaced by cameras and other devices.
