What is a digital loyalty program? A simple guide 2025
Digital loyalty cards in Apple/Google Wallet: stamps vs. points, how it works and a quick ROI example.

TL;DR
- Wallet = no app, a stamp/point in 1 tap.
- Stamps are best for cafés; points are flexible for retail/beauty.
- Simple rules + a clear reward = higher adoption.
- Even a small increase in visits can bring a decent ROI.
How it works
- Add the card via QR/link (≈ 30 s).
- Stamps/points after a purchase (QR or POS integration).
- Automations: thank you, reminder, birthday.
- Redeem the reward at the till (discount/product).
- Optional integrations such as Dotykačka.
Stamps vs. points: when to use which
- Stamps (e.g. 9+1): cafés, bistros; quick to understand, minimal training.
- Points (1 € = 1 point): retail/beauty/mixed; flexible rewards, VIP tiers.
Tip: Start with one mechanic, add combinations only after adoption.
Quick ROI example
ROI = (Incremental profit minus Monthly cost) / Monthly cost
200 members × +1 visit/month × 4 € AOV = 800 € revenue → at a 70 % margin = 560 € profit.
If the tool costs 49 €, ROI ≈ 1,043 %.
Notification templates
- Welcome: "Welcome 🤗 Your first stamp is on us."
- After a visit (2 h): "Thank you! You are one step closer to a reward."
- Reactivation (30 days): "We miss you! Today we will double your stamp."
