You can use the QR-code of the loyalty card. To do that, go to loyalty card overview and click on 'View card

'

Right click on the QR-code and save it as an image so you can place it on a poster, menu card, voucher, etc... .

You can also save the QR-code image from the loyalty card builder (Size is a little bit bigger than the one from the overview).

You can also share the link on your website or on your social media such as Facebook, Instagram, Snapchat, VK.com, etc... .
