What is the difference between fixed and variable value QR codes?

Fixed amount

The QR code has a specific value that you predefine when you order it. The customer thus scans the QR code and only has to confirm the amount. Please note that QR codes with a fixed amount cannot be offered in combination with “QR code stickers with payment information”. Only QR codes with a freely selectable amount can be offered with this solution.

Freely selectable amount

The QR code does not have a specific purchase amount. The customer scans the QR code, enters the amount to be paid themselves and confirms the payment.
