The most easy validation method is a combination of QR code validation and mobile device validation.

Mobile device validation
This validation method adds a validation button to the coupon.
You can enter the validation password to validate the offer or use a simple button without password.
For multiple redeem locations you can have multiple redeem passwords to track the validations per redeem location in the statistics.

QR code validation
We recommend to enable the QR-code validation in combination with the on mobile device validation.
The on mobile device validation will not work if the consumer doesn't have an internet connection or bring in a printed version of the coupon.
If QR code validation is enabled our platform will add a QR code on the validation page or printed coupon.
Scanning the QR-code gives the redeem location the same validation method as "on mobile device validation" but on the device from the redeem location.
