Smart digital hundi for identification of Indian coin and currency using Image processing

India is a country of diversity with different religious views containing 7 crores of people. Most of our country devotees pay their loyal towards lord by offering money, donating jewels and other materials depending upon their economical status. Most of them preferred their donation in the form of money. Hundi is the devotee donating containers in the temples. We proposed to develop an automatic coin and currency counter in the temple to count the total amount of money which is donated using raspberry pi. It can also be used in the number of places where there is an availability of large amount of coin and currency usage such as charities, banks and trusts. In this paper, we proposed to process the images of the input which is inserted into the hundi to find its denomination. The image processing is used to identify both the coins and currencies. Finally, the total amount is calculated by adding the monetary value of each image and displayed using LCD module. Thus, this system can reduce the human effort and also deduces the malpractice rate.
