This is a cool new type of barcode I have not heard of before. The QR code is a way to put up to 4000 letter characters and 10000 numbers in a barcode. I love the fact that you can control the level of accuracy. You can make it so between 7 and 30% of the barcode could be covered and unreadable and no data will be lost because the data is redundant like RAR files can be. It is like stiped harddrives in the way that if one of them is destroyed the others still have the files that were lost on the harddrive that failed. Read about how google charts API works to let you make these cool barcodes.

You can also use it to store a contact including about 10 different parts to it.
It can store a geographic location including how many meters above the area.
It can also store a SMS message, or an e-mail or a calendar event. Try out generating these barcodes and more in the following online demo.

These barcodes will someday be used more as maybe something that can add events to your google calendar or add anyones contact info from a book into your email profile. Mobile phones can read these barcodes and so it is a pretty new technology that will be helpful to someone someday.
