This apparatus is the core of a vending machine’s financial transaction system. It identifies and sorts inserted currency, accepting valid coins while rejecting slugs and counterfeit pieces. A simple example would be a system that uses the weight and size of a coin to determine its value, directing it to the appropriate storage area within the machine. More complex systems might utilize magnetic and optical sensors for enhanced accuracy and security.
Accurate and reliable operation is critical for the profitability and security of vending machine businesses. It prevents losses due to counterfeit currency and ensures customers receive proper change. Historically, these systems have evolved from simple mechanical comparators to sophisticated electronic devices, improving accuracy and security alongside the increasing complexity of currencies. This evolution has enabled vending machine operators to manage transactions with diverse coin denominations and heightened security measures.
