Challenge
- PCI DSS certification and FCA approval, ensuring full regulatory compliance
- Ultra-low latency transactions under 250 milliseconds, delivering a seamless user experience.
- Successful integration of multiple third-party APIs, including GPS, Xero, and CashFlows
Billboards were distributed across thousands of locations. Many remained static or disconnected from real‑time campaign intelligence.
Advertising teams lacked a unified way to verify which creative was running where or to activate location‑based campaigns tied to a user’s movement.
To modernize this ecosystem, a mobile‑first, location‑aware platform was required. The solution needed accurate proximity detection, low‑latency data flows, and seamless integration with Ströer’s backend infrastructure.
The challenge was to build a cloud‑native system that merged IoT beacons, mobile sensing, and dynamic content delivery while remaining intuitive for everyday users.
Key Objectives
- Detect nearby billboards using mobile‑device proximity to IoT beacons
- Identify which advertisement is running at each location
- Deliver real‑time, personalized offers based on user movement
- Build an API‑first integration layer for Ströer’s media systems
- Ensure low‑latency performance across national-scale traffic
- Create a mobile experience that feels instant, relevant, and non-intrusive
- Enable dynamic, location-triggered campaign activation for brands
Solution
- A cloud-native, mobile-first advertising platform was engineered to bridge the gap between physical billboards and digital audiences.
- IoT beacons were deployed across selected billboard locations. Each beacon transmitted location metadata and campaign identifiers. A mobile app was built with real-time proximity detection. When users passed a beacon, the app automatically identified the billboard and retrieved the running creative.
- A geo-triggered engine delivered personalized content at the right moment. For example, users traveling along a highway could receive a limited time offer when approaching a restaurant billboard on the next exit.
- An API-first backend integrated Ströer’s location catalogue, campaign schedules, and creative metadata. Low-latency data pipelines ensured immediate content retrieval and accurate beacon mapping.
- A clean interface presented contextual offers without distraction. The platform was designed for high throughput, national deployment, and easy onboarding of new billboard locations.
- A CI/CD workflow supported rapid feature iteration, enabling Ströer to evolve the system as customer behaviour and campaign needs changed.
Results
- PCI DSS certification and FCA approval, ensuring full regulatory compliance
- Ultra-low latency transactions under 250 milliseconds, delivering a seamless user experience.
- Successful integration of multiple third-party APIs, including GPS, Xero, and CashFlows
- Real-time billboard detection enabled across multiple locations
- Mobile users received contextually relevant ads with minimal latency
- Improved verification of which creative was running at each site
- API-first backend simplified future integrations and campaign automation
- Location-aware ads delivered higher engagement and measurable brand impact
- Foundation created for nationwide rollout of intelligent out-of-home advertising
