Currency identifier for Indian denominations to aid visually impaired

Identification of various denominations of currency is not an easy task for visually impaired people. In India though there are special symbols embossed on different denominations, still the task is tedious for blind people. The lack of identification devices motivated the need of a handheld device for segregation of different denominations. This work attempts to design a device using IR sensors, for Currency identification of Indian Denominations (CiID) to aid visually impaired people. The variation in the voltage level of various currencies, are observed and detection has been implemented. This device has an accuracy of 86%.
