    Bank Notes Recognition Device for Sri Lankan Vision Impaired Community
    (IEEE, 2013-04) Wickramasinghe, K; De Silva, D
    According to government and central bank rules and regulations of Sri Lanka, the bank notes must be changed once a pre-determined period of time. This process had been initiated recently on the Sri Lankan bank note system and had been changed into an array of new bank notes. The bank notes have been designed to the international standard and unlike the old system of notes, apart from the visual differences they are only five millimeters (5mm) longer or shorter from one another. This created a considerable problem to the visually handicapped people in the country because they have been used to identify the old notes by touch. The money detector is a device that has been developed to aid the blind in recognizing the new array of bank notes. The low cost portable device identifies the bank note in two different detection methods simultaneously and gives the user an audible feedback as to what the note is.
