How Summa Works
Summa is a digital loyalty program for local shops. You define a program (e.g. "10 coffees → 1 free"), and your customers collect stamps on their phone — no app download, no account needed. The card runs in the browser.
What you get
You can see at a glance how many active customers you have, which programs are running, and how often stamps are collected. Your customers don't need to install anything — they open their card in the browser.
How it works
- On their first visit, the customer scans a QR code in your shop and gets a digital loyalty card.
- On each purchase, they collect a stamp — via QR scan, NFC stamp, PIN entry, or receipt QR code.
- Once the card is full, they redeem their reward — right on their phone, no paper or codes needed.
Four ways to collect stamps
QR Scan
Staff scans the QR code on the customer's card in the browser. Quick and simple — great at the counter.
NFC Stamp
Staff holds an NFC stamp to the customer’s phone. Under one second, no QR code needed.
PIN Entry
Staff types in the four-digit code from the customer’s card. No accessories needed.
Receipt Stamp
Your POS system prints a QR code on the receipt. The customer scans it at their convenience — fully automated.
