Although most transactions are now made digitally, some rural regions still use real currency for transactions. Coins are now more frequently used than cash at a variety of locations, including bus and train stations, malls, temples, and water systems that operate on a coin system. Obtaining coins is incredibly tough for regular people. A system is created to offer a solution to the difficulty indicated above. One mechanical device that has phoney note detection and an intelligent note to coin exchanger. In the proposed system, when the user inserts the note, it first uses UV rays to determine whether the note is real or fake. If the note is real, it is then taken inside for further processing and a camera takes a picture of it. By calculating the number of pixels and using image processing, it determines the value of the note, and then equivalent amounts of coins are dispensed in accordance with the value. This system will make it easier for regular people to go about their daily lives.
