The most common use is to make a web address easily readable. Like this one:
There are three uses that seem to make good sense. The first use is to be put on your business card. You can send people right to your website without any typing.
The next is on direct mail pieces such as flyers and catalogs. Your existing or potential customers get get straight to the part of your web site where they can get more information on what ever product or service they are looking at. Maybe more importanly, you can track how many times it has been scanned and if you do it right who likely scanned it.
Finally, QR codes on your product packaging. Give your customer access to the latest information on your product when they are making the purchase decision. No one types long cryptic web addresses -- just a simple click of the smart phone app.
Reading a QR Code
Reading a QR code is simple if you phone has the right software. Many of the new BlackBerry phones have a scanner built-in. From the BlackBerry Messenger menu, select 'scan a group barcode'. Then hold the phone up to the QR code until it fills the screen. If it works, it will open your phone's browser and take you the encoded web site.
For iPhones, Android phones and other smart phones, search for 'qr code' in your apps -- you are sure to find several.
Imperfect Technology
Depending on how the QR code is created and how good the camera is on your phone, your software might have difficulty reading it. If you are trying to read the code on this web page and are having difficulty, enlarge the page by pressing Ctrl and the +/= key. When you are done you can press Ctrl and the zero key to return it to normal size.
As the resolution increases on the smart phone cameras, fewer phones will have trouble reading them. It is not unrealistic to think that by the end of 2011 all smart phones will be sold QR code ready.
In the next post, we will show you how to encode your own information in a QR code.
