I am struggling to find a Shopify rewards app that isn't website orientated. it seems all the ones I can find are designed the same and require users to signup with email and password on my website before activating rewards. I am looking for something more similar to square rewards system where on POS all you need is phone number (or email) and it starts tracking rewards. Is there any app like that? I would love to track customers rewards from POS without having to have customers go to my website and create an account.
