OK-RING / Detector


In our society,there is a special crowd --the blind ,need our help.
It is not easy for the blind to identify the amount of money and whether it is counterfeits or not.The traditional counting machines and currency
detectors are based on voice prompt to distinguish truth from false.In consideration of the noisy environment and their self-respect when looked by other people ,we think it is not the most suitable disign for the blind.In order to improve this situation ,we designed a special product which can make counting and checking be completed as soon as their fingers contact the money.
