Availability of coins in exchange of currency notes has been a perennial issue in our day to day transactions. This paper presents the design and development of an automatic coin dispensing machine to resolve this issue. The proposed system constitutes three modules viz. detection of genuine currency note, determining the value of the note and dispensing of equivalent coins. The currency genuineness is evaluated using analysis of security strip with the help of color histogram of image of the currency note captured under Ultraviolet (UV) light. The denomination of the note is then detected by calculating the unique ‘width-height’ ratio of the currency for each denomination. The machine dispenses coins as per denomination of the note if and only if the note is genuine. The proposed system gives an accuracy of 92.12% for detection of the denomination of the currency note and an accuracy of 90.07% for genuineness of the currency note with FRR of 32.81%. The overall system efficiency to dispense the coins of equivalent value is 100%.
