Stmpz: One Content Platform Powering Three Digital Properties
A loyalty programme provider needed to replace tens of thousands of paper stamp cards with a digital platform. But they didn't just need an app—they needed a content infrastructure that could power a customer mobile app, a merchant business dashboard, and a comprehensive admin portal, all whilst maintaining real-time data synchronisation and sub-second performance.
Key metrics: 10,000+ physical cards eliminated, three digital properties running from one content platform, real-time analytics across all channels, NFC-enabled stamp collection.
The Challenge
Stmpz needed more than a mobile app. They needed an architecture that could:
- Power three distinct digital properties (customer app, merchant dashboard, admin portal) from one content platform
- Synchronise data in real-time across all channels—stamps collected on mobile appear instantly in the merchant dashboard
- Scale to thousands of businesses and their customers whilst maintaining sub-second API response times
- Support offline functionality for coffee shops with unreliable connectivity
- Deliver faster interactions than physical cards (no fumbling for paper)
- Provide businesses with real-time analytics, not stale overnight reports
The technical challenge wasn't building an app. It was building content infrastructure that could manage loyalty data, business configurations, customer profiles, promotions, and vouchers—then expose that content through clean APIs to multiple consuming applications.
The Approach
We built a headless content platform that serves as the single source of truth for all loyalty data, then exposed it through performant APIs to three distinct digital properties.
Content Infrastructure Architecture
Drupal serves as the central content hub, managing:
- Business configurations and loyalty programme rules
- Customer profiles and engagement history
- Voucher generation and redemption tracking
- Promotional content and push notification scheduling
- Real-time analytics aggregation
The headless architecture exposes RESTful APIs that power the mobile app, merchant dashboard, and admin portal—one CMS, three digital properties.
Multi-Property Development
Each digital property was built to consume the same content platform:
Customer Mobile App
- NFC-enabled stamp collection (sub-second interactions)
- Offline-first architecture with background synchronisation
- Push notification delivery for promotions and rewards
- QR code fallback for non-NFC devices
Merchant Business Dashboard
- Real-time analytics showing stamps collected, rewards redeemed, and customer patterns
- Promotion creation and scheduling
- Direct customer communication tools
- Voucher management and tracking
Admin Portal
- Multi-business configuration and oversight
- Role-based access control
- System-wide analytics and reporting
Real-Time Synchronisation
Critical to the user experience was ensuring data appeared instantly across all properties. When a customer collects a stamp via NFC tap, the merchant's dashboard updates in real-time. When a business creates a promotion, it appears immediately in the mobile app. We built event-driven synchronisation to eliminate stale data.
Performance Optimisation
With thousands of businesses and customers, the platform needed to scale:
- API response times under 200ms
- Offline support with queue-based synchronisation
- CDN-cached promotional content
- Database query optimisation for real-time analytics
The Results
One content platform. Three digital properties. Zero paper cards.
- 10,000+ physical loyalty cards eliminated - Customers carry their loyalty programme in one app, businesses save printing costs
- Real-time data across all channels - Stamp collected on mobile? Appears instantly in merchant dashboard
- Sub-second performance - NFC stamp collection faster than fumbling for a paper card
- Scalable architecture - Platform supports thousands of businesses with consistent performance
- Direct customer communication - Businesses can now send targeted promotions and track engagement
The platform demonstrates the power of content infrastructure thinking—instead of building three separate systems, we built one content platform that powers all three digital properties, ensuring consistency, reducing maintenance overhead, and enabling future expansion.
