Detecting False Coins With Mouse Sensors

A team of Spanish researchers at the University of Lleida have developed a way to detect false coins using a mouse's optical sensors. The system works comparing patterns in two euro coins, which at the ongoing exchange is about $US15,302.

The system rotates the coin, sampling its surface using the 30 x 30 pixel resolution optical sensor. Then it compares it to a stored model, giving you the nay or the yay with more accuracy than anyone, or about the same accuracy as an expert. [El Mundo — In Spanish]
