The Indian Institute of Technology (IIT), Ropar, has developed an app Roshni that would help the Visually Impaired to recognise currency notes. The app can recognise both old and new notes and gives audio information as to which note you are holding in your hands.
This app was launched in Chandigarh. Roshni is the first Android app, which recognise INR currency notes. The user has to bring the currency note in front of the phone camera and the App would give an audio intimation about the currency note denomination.
