QR codes are turning up everywhere. They are usually black and white and square...boring! Unitag gives you options.
QR codes can include a background picture.
At RootsTech Thomas MacEntee more or less indicated that QR codes should be on just about anything that you can get them to stick to...a tee-shirt, a mug, anything printed, gravestones... However, as you can see, you don't need to be stuck with the plain black and white version. You can add color and interest. To play with this too cool tool, visit Unitag (http://www.unitaglive.com/qrcode) and get creative.
