Treuli is a digital loyalty program for local businesses such as cafés, bakeries, ice cream parlours, restaurants, hair salons and retail shops in Germany and Austria. Customers collect points by scanning the TSE or RKSV QR code that many tills print on the receipt. Without a QR code on the receipt, staff book points in the admin area or hand out single-use points QR codes. The loyalty card lives in the browser, in the Treuli app for iPhone and Android, or in Apple Wallet and Google Wallet. Merchants set their own rewards, run campaigns, offer birthday and referral bonuses and customer tiers, and see who comes back. No changes to the till and no extra hardware. Treuli is built in Chemnitz, Germany, and hosted in the EU. The Free plan costs nothing; Starter and Business come with a 14-day trial, no credit card required.
