Below are a few ways to use the bar code scanner, not all of them are what you may expect them to be.
The most obvious is to find better deals on items. When using the preloaded bar code scanner on your device, simply scan the item. When the device recognizes the item, you can select Search the web.
Depending on the item you scanned, you are taken to a Google search for the product. If you have an add-on app installed, such as Google Shopper, you will see other options.
Other applications use a bar code scanner to help you search in different ways. Most of them allow you to not only scan the bar code, but also let you take a picture of the front of select items. Right now most are limited to things like the covers of DVDs, books and video games.

QR codes are a considered a 2D or 2 dimensional bar code. Because of the additional dimension, these bar codes can contain much more information.
Some marketers are using QR codes such thing as:
- Giving you more information about a product instantly
- Checking in at a location
- Give directions or point out a location on a map
Another common use for QR codes is installing an application. Sites like Appbrain let you display the QR code for an application right on your computer screen. When scanned, you are taken to the download page in the Android market.
In my opinion, the bar code scanner is one of the most useful, yet under discussed application on the Android devices.
