ROBUST & EFFECTIVE COIN EXCHANGER SYSTEM WITH FAKE NOTE DETECTOR

Now a day the requirement of coins in our day to day transaction at public places such as, shopping malls, railway stations, multiplexes, bus station, and parking places, even in rural areas where nowadays coin telephone system is used, and many more is increasing rapidly. The main motive of designing this efficient and simple machine which will fulfill need of coins for transactions. In olden days the value of coins was much more than what it is today. Thus the system is designed so far that the people will not face problem of coins in public places. This project will provide coins for note of respective value, for this purpose we have developed mechanical coin dispensing model which will accepts the note inside system and checks whether note is fake or real, if it is found that note is real camera takes picture of that note. After that this will find out its value using image processing technique and then according to that value equivalent number of coins are dispensed from dispenser unit. Thus in this manner we are trying to design a robust and efficient machine which will be having a very low production cost as compared to other existing machines. In this system we have developed a MATLAB algorithm for image denomination to detect the value of a particular note, and we have implemented a fake note detection unit using Ultraviolet LED and photodiode terminology.
