Turn a photo of your paper flyer or punch card into an Apple/Google Wallet pass. Connect Shopify and your passes carry real discount codes that redeem at checkout. Connect Square and the register applies the discount the moment the pass is scanned — instantly, even offline, no extra hardware. Run a full loyalty loop: welcome offer → points → reward, with the card in the customer's wallet updating itself at every step. No customer app to install. Free to start with welcome credits.
