QR codes are going to be the next great tech you need to know about. Remember when bar codes first became big (that is, if you’re over a Certain Age)? QR codes may just become even bigger than regular bar codes!
What is a QR code?
“QR” is short for Quick Response. QR codes were developed in Japan in 1994 to help businesses transmit information quickly and efficiently. A QR code is type of bar code, a square with oddly patterned squares within it, kind of like a crossword puzzle gone horribly wrong. Here is an example of a QR code (this is the QR code for this website, The Wonder of Tech):
If you scan a QR code with a scanner, it may reveal all sorts of information such as website addresses, contact information, nutritional information at restaurants, museum exhibit information, songs, book chapters, pictures, etc.
Some books now have QR codes revealing additional information from the author, video, audio tracks and places for readers to leave comments.
If you’re a realtor, you could put a QR code on your listing signs in front of your properties so potential buyers could scan the codes to get more information.
If you’re running a convention, you could provide attendees badges with QR codes containing their contact information for other attendees to scan.
You could put a QR code on the back of your business card to give quick access to your website.
Here is a photo of a hotel in Dubai that decided to go all out with its use of QR codes:
Please post a comment if you visit this hotel. I would love to know what a scan of its QR code reveals!
The possibilities are endless which is why the use of QR codes is soaring.
Do I have to buy a scanner?
No, one of the great things about QR codes is that you might already have a scanner in your pocket, your smartphone with a camera. By using a free app, you can use your smartphone to scan a QR code and have the information appear on your smartphone screen.
Which apps work as QR code scanners?
Google, which is free for Android phones and iPhones, works as a QR code scanner. I have tried some other free QR code scanners from the App Store, AT&T Code Scanner and QR Code Reader, but they didn’t work. I also bought the app quiQR for $1.99. What I like about this app is that it scans quickly and it also generates QR codes, such as the QR code above.
How can I test this out?
First, if you have a smartphone, open your Google app. Click on the camera icon in Google and point your phone camera lens at the QR code above. Click on the camera icon on this screen and scan the QR code. Your result should be wonderoftech.com. If you want to try another QR code, scan the QR code on the sidebar to this blog. That will give you a slightly different result.
Having fun? Search QR codes and see how many cool uses of QR codes you can find.

Perhaps a QR scanner will soon become your Killer App?
Big Tech News Tomorrow!
I know from the questions I’ve received that many of you are eagerly anticipating the iPad 2. Tomorrow is the big announcement where Apple will reveal the latest features, pricing and launch date of the iPad 2. There has been much speculation about the new features of the iPad 2, including whether the device will have a rear-facing camera. Many people have questioned why anyone would want a rear-facing camera on an iPad because of its size. If Apple puts a rear-facing camera on the iPad 2, it will be more for using apps such as QR scanners than for taking pictures. If Apple doesn’t put a rear-facing camera on the iPad 2, then it will have a hard time competing with Android tablets, such as the Xoom, which do have a rear-facing camera.
We will find out all about the iPad 2 tomorrow!
