Abstract:

The present invention is a system of currency identifier that recognizes the value of Indian currency (rupee) for the vision impaired. The device is capable of identifying the denomination of the currency and it displays the amount to the vision impaired via retractable solenoids arranged in the standard Braille positions. The input unit of the device consists of infra red emitters and sensors. The infra-red light is allowed to pass through the currency and is captured by the sensors, outputting voltage readings. The microcontroller determines the denomination using these voltages and sends output signals to extend the corresponding solenoids.
