In Brazil whenever you buy something, you get a small tax refund you can donate. But only if you mail in the receipt or put it in a donation box. Now that's changed with nfscan. An app that takes a photo of your receipt. Then all you have to do is hit send and you've donated some money. More over, nfscan is open source, so all non-profits can use it and integrate it into their organizations.
