Loyalty for cafés & coffee shops
Your regulars already come in every morning. Put your stamp card on their phone, stamp it in two seconds at the till, and they'll never leave it in their other coat again.
Why cafés use Deengle
The 8am rush is no place for admin. The customer shows a six-digit code, your barista types or scans it while the shot pulls, and the stamp lands. Quicker than the rubber stamp ever was.
No card left in the other coat, no washing-machine casualties, no wallet full of half-finished cards from every café on the street. Theirs lives on their phone — always with them at the till.
Every stamp is confirmed at your till with a one-time code. No photocopied cards, no double-punching, no free flat whites you never sold nine coffees for.
You know the 2pm slump. Push an offer to every saved card — "£1 off any cake with a coffee after two" — and give the morning crowd a reason to come back twice in a day.
How it works
"Buy 9 coffees, the 10th free" — or 6, or 12, your call. Pick a design that matches the counter, add your menu, publish.
Print one poster and prop it where the punch cards used to sit. Customers scan while they wait for their order — the card is on their phone before their name's called.
They show a code at the till; your barista confirms it in two seconds. Ten coffees in, the free one credits itself — no maths, no arguments, just hand it over.
