I'm curious about how DC nonprofits are using QR codes.
Don't know what a QR code is? Go to Wikipedia (https://secure.wikimedia.org/wikipedia/en/wiki/QR_Code) for a technical explanation. Or, accept that QR codes are kind of like bar codes - except that a QR code as nonprofits tend to use them is a link to a web site or blog.
