A new donation trend in Europe could become the next donation craze after wristbands.
The Donny Card idea was blogged on phatgnat.com - a research website that is intended to help businesses connect with the youth market.
Donny Cards are displayed in a handful of petrol stations and supermarkets in the Netherlands. The cards are added to other purchases and, once the card is scanned at the register, a EUR2 donation (or whichever amount is shown on the card) is added to the bill and the merchant credits the beneficiary.
The founder of the Phatgnat site, who goes by the name of DK, said: "I think it's a fantastic idea that could catch on in the same way that wristbands did."
In The Netherlands, charities using the cards include WWF, Oxfam, the Dutch Red Cross and Amnesty International.
