Coins have become a significant part of today's economy and are continuously being distributed, along with banknotes, for daily transactions in the most conventional methods. The modernized circulating currency method relies heavily on coin sorting and counting machines to prevent inconsistencies when handling and calculating coins. While the innovation reduces the need for human resources and revolutionizes the way establishments work with large sums of coins, accuracy in differentiating coins becomes an issue in some existing designs. The prototype uses light occlusion and measures the energy of the coin impact to identify the denomination. The prototype shows promise in being able to identify four Philippine coin denominations.
