“QR codes can hold thousands of alphanumeric characters of information,” says WVU’s Graham, in his blog. “Their ability to hold more of your information and their ease of use makes them practical for our pages of information on the digital signage.”
You can find QR codes everywhere from newspaper and magazine articles, ads in these and in large signage like in bus stops and train stations, and also in digital signage displays. (Some people are even putting QR codes on their business cards!)
These QR codes are being used to provide everything from URLs, Vcard contact info and Vcalender event info to Wi-Fi logins, e-mail addresses, and phone numbers. By scanning a QR code with your smartphone’s camera — assuming you’ve got one of the right apps installed — your phone can be sent to a given Web page, send an IM, SMS or e-mail, etc.
To make a QR code, you will, of course, need a code-generating app, but those are readily available.
“Interactive wayfinding is one use for interactive digital signage,” says Jay Kirtley, business development manager, Tightrope Media Systems. “We let you include QR codes on your directories and maps, so people can carry the map with them.”
Other popular uses for this interactivity, says Kirtley, include trade shows, to let people download brochures directly, and for employee bulletin boards instead of posted paper notices.”
Mike White, President, Multi-Media Solutions, Inc., points out, “The QR codes and other means of being interactive with the screen are extremely valuable for measuring the effectiveness of content, being able to validate that people are digesting the info.”
So raise your hand — or wave your phone — if you want people to interact with your digital signage!
