Once you’ve built and published your referral campaign you will be able to generate a QR code so that people who want to become referrers can scan to join your referral campaign.
This is a feature that is very valuable to businesses that have a brick-and-mortar store, an office, an eCommerce store, or anyone that sends out physical material to their customers such as deliveries, thank you cards, etc. You can download your QR code and display it on your products with a Call To Action so that your customers can easily scan the code to access your referral program and register to get their unique referral link.
To get your campaign QR code - go to your campaign builder and go to your "Outputs" step. This is the last step in your campaign builder. Here you can select the QR Code option and download it.
