2 October 2026A Card terminal on the vending machine enables cashless payment by debit and credit card as well as by smartphone or smartwatch.
Function and area of use
The terminal is connected via the MDB interface and needs a data connection, usually via mobile network. The customer selects a product and holds a card or smartphone to the terminal, and after approval the vending machine dispenses the goods. Many systems first reserve the amount and only debit it after successful dispensing.
In addition to the purchase, there is usually a monthly basic fee and a fee per payment. Many terminals also supply sales data for restocking planning.
Advantages
- More revenue, because customers without cash can buy
- Less cash in the vending machine
- Sales data in real time
Frequently asked questions
Can I retrofit a card terminal?
