If you are someone that owns a G1 phone from T-Mobile it’s somewhat likely that you’ve used one of the applications that is available to read QR Codes.
There are two very popular applications that make use of scanning potential:

• Shop Savvy

• Compare Everywhere

Both of these applications will allow its user to take a photograph of any products UPC through the built in camera. After you’ve done this you are able to make price comparisons on the web.

Both Shop Savvy and Compare Everywhere utilize open ZXing’s open source software. Other developers of the Android are able to use intents in order to bring barcode scanner functionality into their own program. One such example would be that of the Torrent Droid.

Sharing QR Code Information

Other than just typical UPCs the ZXing software allows support for all of the subsequent codes:
• UPC-A&E
• EAN8&13
• Code 39
• Code 128
• QR Code
• Alpha quality data matrix
• ITF
A QR (quick response) code is a barcode which is 2D and able to store a lot of information, much more than any standard UPC code.
Inside of a QR code you can find:
• Text
• Hyperlinks
• Geo location
• Contact information
• Much, much more
The QR code is able to handle up to 250 characters. The QR code is something that is very common in Japan but really hasn’t taken off in the U.S. yet.
If you look for the barcode scanner share option for Android you’ll be able to find a lot of the cool uses for it. Just pres the menu then share and the user can easily send their contact information as well as text, bookmarks from the clipboard to any other G1 phone. Free of charge, users can create their own personal QR codes through visiting the following link.

Once you’ve created a QR code of your own there are many creative ways to use it. You can put them on the backs of business cards so someone is able to scan your information into their phone in just seconds. An advertiser can put them into their print media to drive traffic to their website. A band could put them on the backs of their CD cases to allow you to preview audio or buy tickets to their concerts. There can be secret messages put inside of them for people to find.
There are so many different and innovative ways to use them. Think about them for you and your business and how you can make them work for you.
