I’ve seen them in magazines. I’ve seen them included in some street advertisements. I’ve seen them on the doors of some businesses. What the heck are they?
Great Error correction in 2D bar code
These are QR Codes – Quick Response codes. The technology has been around since the 1970′s in different versions (think barcode at the grocery store). The one I’m using above is known as the 2d barcode (as in two dimensional). These QR codes allow an ever increasing number of smart phone users to use an app on their phone to access the extra information included in the 2d barcode. This can be a unique message, an internet web address, or link to a special offer. In the case above, you get my email address, my web address, and a quick message.
To create the QR code above, I used the RACO Industries QR code generator which allows for different levels of error correction. That means I can stick my silly mug in the middle of the barcode and still have enough information available to correctly convey the message. It works really well. Try it out.
If you don’t have a barcode reader, check here:
Use your smarthphone app and point your phone at the QR code. Pretty cool, eh? Gets you thinking about all the possibilities. Doesn’t it? How will you use it?
My QR code above is going on my business card. How about you?
