A new interactive feature for a leading retail destination

Hoog Catharijne, one of the Netherlands’ largest and busiest malls, set out to create a community-focused experience where children and families could donate, swap, or pick up items such as toys and books. Working with Groundbreakers, Klepierre developed a locker-based concept supported by a custom Keynius system, giving visitors a safe and self-service way to exchange items within a high-traffic retail environment.

No digital system for item exchange
There was no existing structure for visitors to safely donate, receive, or swap items in the mall.

Experience-driven requirements
The concept needed to be intuitive, engaging, and visually aligned with Groundbreakers’ experience design.

Need for custom workflows
Standard locker flows could not support the required “donate,” “receive,” and “swap” functionality.

A Smarter Solution

Discovery
Klepierre and Groundbreakers developed the concept and user journey, and partnered with Keynius to provide the digital tools to deliver a structured donation & exchange experience.

Solution & Recommendation
Keynius delivered 20 Elite Plus smart lockers and a fully customized donation web app, enabling visitors to donate, receive, or swap items with a simple, guided interface available on mobile, tablet, or Smarty device.

Customization & Collaboration
Groundbreakers created the visual and experiential components, while Keynius provided the locker technology and web app.

Why Keynius
The Keynius platform offered full workflow flexibility, branding customization, and the ability to configure donation products, distribution logic, and multilingual settings.

The Results: A Scalable, Configurable Sharing Experience

With a configurable Keynius web app and custom locker setup, the mall now offers a streamlined, repeatable experience that can easily expand to other Klepierre locations.

Conclusion

The partnership between Klepierre, Groundbreakers, and Keynius resulted in a unique smart-locker experience that encourages families to donate and exchange items in a safe and enjoyable way. Powered by a flexible donation web app , the solution supports multiple item-exchange scenarios and can be branded, configured, and managed to suit any location. With the initial installation complete and strong interest from visitors, Klepierre plans to replicate this concept in additional malls, creating a series of community-centered spaces inspired by the success at Hoog Catharijne.
