A billboard at Hamburg Airport does not just ask for money. It takes a 2-euro donation and immediately shows what that coin can do.
Misereor has been committed to fighting poverty in Africa, Asia and Latin America for over 50 years. To drive more donations, they install a billboard with a donation box built into it. When people put in 2 euros, the billboard brings to life how that coin can help across Misereor’s aid projects.
The billboard also links the offline act to an online conversation. It takes a photo of the donor and posts it to the campaign’s Facebook app. A QR code on the billboard lets donors share the promotion on their own Facebook page.
How the interaction is designed to convert
The mechanism is a tight, three-step loop. Physical donation triggers an immediate visual payoff. The payoff translates “impact” from an abstract promise into a concrete scene. The scene then becomes shareable proof through an automatic photo post and a QR-driven sharing prompt.
In high-traffic public spaces where attention is fragmented and dwell time is unpredictable, donation design wins when it minimizes steps and makes impact visible immediately.
Why it lands
This works because it replaces guilt with clarity. You do not just hear that your money helps. You see a specific outcome the moment you give, which makes the decision feel both meaningful and finished.
Extractable takeaway: If you want more donations, build a “give. see. share.” loop where the act of giving triggers instant, legible impact, and the sharing step is optional but effortless.
The real goal behind the 2-euro choice
The real question is whether a donation ask can feel immediate, visible, and worth doing before the traveler walks away. A 2-euro ask is small enough to feel impulse-safe, especially in an airport moment where people already make small purchases without overthinking. The campaign then uses the experience to recruit advocates, not just donors, by turning each donor into a visible participant online.
What this donation design gets right
- Make the donation amount frictionless. Small, fixed amounts reduce decision paralysis.
- Show impact instantly. The payoff must happen before the donor walks away.
- Bridge offline to online. Capture a shareable artifact, but keep it consent-friendly.
- Keep the interface obvious. A slot, a prompt, a clear result. No instructions required.
A few fast answers before you act
What is “The Power of a Coin”?
An interactive airport billboard for Misereor where a 2-euro donation triggers an animation that shows how the money helps, and then offers easy sharing via photo and Facebook.
What is the core mechanism?
Donate a fixed amount, get an immediate visual “impact reveal”, then optionally share via an automatically posted donor photo and a QR-enabled share prompt.
Why is the instant animation important?
It turns “trust us” into “watch this”. Immediate feedback reduces skepticism and increases the chance of giving in-the-moment.
What is the biggest risk with the social layer?
Consent and platform drift. If posting feels automatic in a way donors did not expect, or if platform permissions change, the sharing layer can backfire or break.
What is the transferable lesson for other causes?
Design the donation moment like a product demo. One action triggers a clear result, then the donor can share proof without extra effort.
