# How does the validation process of the loyalty cards work?

In this article I will explain you how to add new stamps or points to a loyalty stamp card.  
  
*   Add redeem location(s) to your loyalty card.
  
Make sure you have at least 1 redeem location for your loyalty card.  
Each location has a unique email + password combination.  
The merchant will use this password to identify himself and add points/stamps.

*   Merchants can use 3 different validation methods:
  
  
*   on mobile device: they can enter their password on the customers phone.
  
*   by scanning the QR code: they can scan the QR code and enter their password on their own device.
  
*   by using the validation app/widget. They can login once and scan the QR of enter a unique code from the consumer to add points.
  
  
*   The merchant will see the consumers profile and is able to select how many points or stamps he wants to give. You are able so setup a validation limit per day/per consumer in the advanced settings of the loyalty card. Each given points or stamps are tracked in the merchant logs and can be found in the loyalty card statistics.
