QR codes are being used more and more each day. Therefore, it makes sense to create a solution where customers can use QR Codes to pay for products in a vending machine.

In this tutorial, we will cover how to set a QR code payment method in a vending machine. As we all know, this innovative payment method is highly popular due to its convenience and ease of use. 

There are many different application scenarios for this solution. One example is in companies that distribute credit to employees or visitors to buy products. Another example would be a system where you pay for a QR Code and get a printed or mobile version, which you can use later on any machine that accepts that specific QR Code.

For this solution, consider that your machine needs to support MDB.
