Android barcode scanner apps are old news to Android veterans, but if you are new to Android, a good barcode scanning application is a ‘must-have’ for your Android device.
An Android barcode scanner uses the device’s built-in camera to take a picture of a barcode and then the app decodes the contents of the barcode for your use. Now you may think this may not be very useful, or even interesting, but combine this barcode scanning technology with a database of products, a library of books or cds, or any other large set of data and you’ve got a very useful lookup tool.
One of the most popular uses of an Android barcode scanner app is for looking up products on the Internet. This allows you to be shopping (even in the store ready to buy something), and do an instant price check to see if you are getting a good deal or not.
Another common use for scanning barcodes with your Android device is navigating to websites. This one is extremely handy and allows you to, again, just point your phone’s camera at the barcode and navigate, in a matter of seconds, to the encoded website. This is being picked up on by advertisers and I now regularly receive mail with barcodes (similar to this one) printed on the outside of the envelope. What a fantastic way to make it easy for people to reach your website.
An Android barcode scanner app can be used for much more that what I’ve just highlighted, but those are a couple of my favorite uses.
