MISEREOR built a credit-card reader into a poster and let donors slice the bread

MISEREOR, Germany's biggest Catholic aid organisation, faced declining donations and 'donation fatigue': people saw pleas for money everywhere and had learned to ignore them. The brief to Hamburg agency Kolle Rebbe was to make even a small donation feel big in a way that was entertaining, not guilt-driven ('playful, not pitiful').

The insight came from a payments statistic: over 40% of payments in Europe were made by credit card. Instead of asking people to give cash or visit a website later, the agency put the point of payment inside the advertisement. The result was the Social Swipe — billed as the first interactive billboard to accept credit cards — installed in international airports.

A swipe through a slit in the poster donated €2 via a secure instant authentication process built with Stripe. The same swipe triggered the creative: on screen, the card sliced a piece of bread from a loaf, symbolising a daily meal for a family in Peru, or cut through ropes binding a child's wrists. Later, the €2 charge appeared on the donor's bank statement with a note asking whether they wanted to turn the one-off swipe into a regular donation.

The poster won three Clio Awards gold medals in 2014, was recognised with a World Summit Award in Inclusion & Empowerment in 2015, and became one of the most-cited examples of experiential fundraising — the template for 'contactless donation' installations charities still copy today.

Put the card terminal inside the ad itself

Zero friction: impulse and payment happen in the same second, with no forms, websites or follow-up steps to abandon.

The mechanic is the message: the physical swipe performs the metaphor (cutting bread, cutting ropes), so the donor literally acts out the impact.

Built on a real behaviour shift — 40% of European payments were already by card — rather than asking people to learn anything new.

Instant emotional feedback loop: the animation paid off the donation immediately, which static posters and cash tins cannot.

The bank-statement follow-up converted one-off swipes into recurring donors, compounding the value of each interaction.

When the medium is the checkout, no step sits between impulse and action. Build the donation or purchase into the channel where the payment behaviour already lives.

The Social Swipe won three gold medals at the 2014 Clio Awards for Kolle Rebbe and took a 2015 World Summit Award (Inclusion & Empowerment). It seeded a whole genre of interactive donation media — contactless-giving billboards and card-accepting installations are now standard charity fare. MISEREOR and Kolle Rebbe continued the 'playful, not pitiful' partnership with later award-winning work.
