The application Barcode Scanner is an Android app, from the open-source project ZXing (short for Zebra Crossing), that allows an Android device with imaging hardware (a built-in camera) to scan barcodes or 2D barcodes and retrieve the data encoded.[2] Information encoded often includes web addresses, geographical coordinates, and small pieces of text, in addition to commercial product codes. This Android-based system has similar functionality to a hardware barcode reader.

This application supports many different types of barcodes, including those used to identify products in commerce. The Barcode Scanner can automatically search the Web to identify a product with a barcode and use, for example, price-comparison information between vendors.
The application can decode several 2D barcodes including the widely used QR Code and Data Matrix. QR codes are often embedded in websites; Barcode Scanner can open a browser at the encoded site, for example, facilitating the download of an application.
As of May 2016[update], this is one of the most downloaded Android applications as listed by Google Play, with over 600,000 ratings and over 126 million user installs.[3][4]
Detection performance of ZXing was assessed on close to 2 million synthetic images for three types of barcodes: QR Code, MaxiCode, and EAN-13 1D barcode. Problematic angles where decoding often fails were found, for example 45, 135, 225 and 315 degrees for QR Codes.[5]
