30 Creative QR code business cards

"A quick response (QR) code is a two dimensional code that can be scanned and read by smartphone cameras to transfer information. The information can then be encoded to text, add a vCard contact, open a URL or much more.

So, by placing them on a business card, you can digitally pass on your contact details, direct people to a website, send them to a Flickr photo set or Facebook fan page or offer a special discount etc.

Hopefully the examples below will help to inspire you on how QR codes can be incorporated creatively in your designs. Or at least, provided a few interesting ways that they can be used to connect offline and online media."
