This is the Barcode application. Now this application will decode data matrix barcodes. So in this we will encode them, but for right now they will only decode them. So it needs a camera which is available only on the iPhone. What you will do is you will take a picture of this barcode, click OK, and then it will register. You see this a lot on your computer hardware like monitors, or computers. Just take a picture and this will scan it. Figure out what the manufacturer is, what the model number is, the website to go to for support. Anything and everything you need to know about that kind of hardware.
