You usually see them in advertisements, on websites, or on product packages: those small square barcodes that look a little different than the traditional one-dimensional barcode that you're used to seeing.
Short for Quick Response code, a QR code is a type of two-dimensional barcode that can hold vastly more data than traditional one-dimensional barcodes can. For mobile device users, QR codes can provide a fast
and easy method of data entry for things like contact information or website addresses.
This is the same data expressed as a QR code (top) and a Code 39 barcode (bottom). |
Scanning a QR code or Other Barcode
Barcode Scanner is available for free from Android Market. It uses your device's camera to capture a barcode. Once the barcode is scanned, the app will give you the appropriate options for the information read (URLs will allow you to navigate to a web address, product bar codes will allow you do a product search, file download links will allow you to download a file, etc.)
Line up a barcode... |
...and get the information from it, with options for what to do with it! |
Barcode scanner also allows you to share information with other tablets and smartphones by creating a barcode on your screen that another device can scan.
