Misereor: The Power of a Coin

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.

EVOC: The Indestructible Billboard

A backpack is mounted into a bus stop billboard. People step up, throw their hardest punch, and a display instantly shows the force of the hit and how much of it the backpack absorbs.

EVOC wanted to highlight its LITESHIELD protective technology, positioned as shock absorption with everyday wearing comfort. Publicis Munich created a billboard that lets passers-by physically test the backpack’s impact absorption. The unit also ties into Facebook, described as photographing participants and posting the image so they can tag and share their attempt.

The hardest recorded punch is reported as 11.30 kN. Definition-tightening: kN, kilonewton, is a unit of force, so the number is the proof-point for how much impact the demo measured, not a vague “strong” claim.

A product demo disguised as street entertainment

The mechanism is simple. Turn the product into the interface. The billboard does not claim protection, it measures an impact in public and shows both the hit and the absorbed portion in real time.

In performance-driven consumer categories, an outdoor experience that converts a spec into a felt moment can create belief faster than any explanation panel ever will.

Why the Facebook loop matters

The punch is the hook, but the share is the multiplier. By capturing the moment and attaching a score, the activation creates a lightweight competition mechanic, then hands people a reason to post that is about them, not about the brand.

Extractable takeaway: Proof travels when the moment is both measurable and share-ready, so design the interaction and the publishing loop as one system.

Reported results from coverage include around 97 hits per hour and a 220% increase in Facebook fan activity during the campaign window. Those figures are part of the story because they show what happens when the product truth is both playable and publishable.

What EVOC is really buying

This is credibility and recall. If you let someone try to break your protective promise in public and the product holds, the brand earns a kind of trust that polished messaging struggles to achieve.

The real question is whether your proof moment is verifiable at a glance, or whether it reads like a gimmick.

Proof-led stunts are worth doing only when the measurement is instantly legible and the audience feels it cannot be faked.

Proof-led activation moves worth copying

  • Instrument the claim. If you say “absorbs impact,” measure impact and show the absorbed portion.
  • Make the demo social by default. Photo plus score is a repeatable share trigger.
  • Keep the interaction one-step. No instructions wall. One obvious action, one immediate payoff.
  • Design for bystanders. Watching someone else punch is part of the persuasion.

What is EVOC’s “Indestructible Billboard”?

An interactive bus stop billboard in Berlin that lets people punch an EVOC backpack, then displays the measured force and the absorbed portion as a live product demonstration.

What does LITESHIELD refer to?

EVOC’s protective backpack technology, positioned around impact absorption and back protection while still being wearable for sport use.

Why add Facebook to an outdoor activation?

Because it turns a one-off street moment into shareable content. A photo plus a score gives participants a reason to post and compare attempts.

What does “11.30 kN” mean in plain language?

It is a reported peak force reading from the activation. kN is a unit of force, so the number is meant to quantify the strongest recorded hit.

What is the biggest risk with “proof” stunts like this?

If the measurement is unclear or feels fake, trust collapses. The display must be instantly readable and the interaction must feel authentic.

McDonald’s: Pick N’ Play Billboard Game

You are walking through central Stockholm and a McDonald’s billboard does something unusual. It invites you to play a quick Pong-style challenge on the screen, using your own phone as the controller.

DDB Stockholm has created another interactive outdoor campaign for McDonald’s Sweden called Pick N’ Play. Passers-by use their mobile phones as controllers to play for a chosen McDonald’s treat. If they last for more than 30 seconds, they score a coupon that earns them free fast food at a nearby McDonald’s.

Reportedly, the interaction avoids an app download and instead uses a simple mobile web flow, with proximity checks (via phone location) so only people physically near the screen can play.

Why this one pulls a crowd

The mechanic is instantly legible. Most people recognize Pong in a split second, which lowers hesitation and increases participation. The billboard also creates a public spectacle, which adds social proof and makes stopping feel normal, not awkward.

Extractable takeaway: This is rewarded interactivity, meaning the payoff is gated behind sustained attention instead of a tap. In outdoor, that simple “earn it” rule turns a public glance into a deliberate, measurable action.

What McDonald’s is really buying

The prize is not the point. The real value is a measurable bridge from street attention to store visit. A time-based win condition filters for people who are actually willing to pause, focus, and then act, which makes the coupon a higher-signal trigger than a generic discount blast.

The real question is whether your DOOH idea can turn a public moment into a private, trackable action without adding friction.

In global consumer brands and retail environments, interactive digital out-of-home earns its keep when it connects a public moment of attention to a private, trackable action on a personal device.

Steal these moves for your next DOOH game

  • Use a mechanic people already know. Familiar rules beat clever rules in outdoor contexts.
  • Make the phone the interface. It turns a billboard into a controllable experience and a trackable session.
  • Reward endurance, not clicks. Time-in-game is a simple proxy for real attention.
  • Close the loop fast. A coupon that can be redeemed nearby turns novelty into footfall.

Last year they had challenged pedestrians to take pictures of McDonald’s food to get it for free.


A few fast answers before you act

What makes an interactive billboard work in practice?

An interactive billboard works when the invite is understood in seconds and the first action feels effortless on a phone.

Do you need an app to control a billboard with a phone?

No. Campaigns like this are often built as mobile web experiences so participation is immediate and friction stays low.

How do you stop people from playing remotely?

By verifying proximity. A common approach is using phone location to confirm the player is physically near the screen before the session starts.

Why use a 30-second target?

It is long enough to prove engagement, short enough to feel achievable, and simple enough to explain with one line of copy.

What is the business upside versus a normal coupon?

You get a higher-intent audience. The coupon is earned through attention and action, which tends to correlate with stronger redemption and store visitation.
