A blind person has difficulty in reading and distinguishes between real money and counterfeit money. Required a tool that can help blind people to solve this problem. Rupiah money have a color difference on every nominal and hidden image that will glow if irradiated with ultra violet. It can be used to read nominal and authenticity. With Arduino microcontroller that combine with GY-31 color sensor and BH1750 light sensor can be used to create tool that will help the blind people to read and distinguish real money and counterfeit money.
