An automated cash handling device integrated within a vending machine verifies the authenticity and denomination of inserted banknotes. This device typically employs a combination of optical and magnetic sensors to analyze the currency’s features, comparing them against known standards for genuine bills. Accepted currency is then stored securely, and a corresponding credit is added to the user’s balance for purchase.
Accurate and efficient currency handling is crucial for unattended retail. These devices enhance transaction security, minimizing losses from counterfeit or damaged bills. They also streamline the purchasing process, offering convenience for consumers and reducing the need for frequent manual cash collection by operators. The development of sophisticated validation technology has been essential to the growth and widespread adoption of vending machines.
