I use my company's platform in my marketing efforts to create cool interactive apps that can live on our Facebook page, blog and website. When we have a great new idea or are exhibiting at a tradeshow, we can quickly login at www.snapapp.com - generate a QR code for an app and print them out for table tents & on hand-outs to use at Tradeshows or during client meetings. Our sales team loves it! We just recently did this at a local Web Innovators conference with Patriot's Tickets giveaway - go ahead, you can register if you want http://app.snapapp.com/webinno :0) Game is at Gillette in MA so you need to be local. The great thing with using QR codes like this is that they're so quick and easy.
