Peer Reviewed & Fact Checked

1. Cashless Payment

A QR on each product slot or on the machine panel initiates a payment flow via the machine operator's payment gateway. No coins, no card terminal — just a phone scan and approve.

2. Allergen and Nutritional Info

A QR beside each item slot links to the product's full nutritional panel and allergen list. Customers with dietary requirements can check before purchasing.

3. Fault Reporting

A QR on the machine links to a fault report form pre-filled with the machine ID. Customers report jammed items, payment failures, or out-of-stock slots without calling an 0800 number.

4. Operator Restocking

A QR accessible to operators opens the stock management view for that machine, showing current levels and restocking history. Efficient route planning for multi-machine operators.

Frequently Asked Questions

Can customers pay via QR on any vending machine?

Only on machines integrated with a QR payment gateway. Retrofitting existing machines requires a connected payment module.

Does a vending machine QR need to be unique per machine?

Yes. Encode the machine ID in the URL so payment, fault reports, and stock data link to the correct machine.
