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.

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.)
