Coin Hoppers and Carousels
For storing and managing coins, vending machines incorporate coin hoppers and carousels. Coin hoppers store and dispense a specific denomination of coins, while carousels provide improved storage capacity by allowing multiple denominations to be readily available. These mechanisms help maintain an adequate supply of coins for change dispensing and customer transactions.
Change Dispensing
Change Dispensers
Change dispensers are an integral part of snack vending machines, ensuring that customers receive the exact change owed to them after a purchase. These devices are designed to hold and dispense various coin denominations, providing a convenient and efficient solution for handling change transactions.
Dispensing Coins and Bills
Once the vending machine calculates the change owed to the customer, it initiates the dispensing process. Depending on the transaction and the available change, the machine can dispense coins, bills, or a combination of both to meet the required amount accurately. This seamless process ensures a positive customer experience while maintaining the integrity of the vending machine’s currency management system.
