ZXing (“Zebra Crossing”)

ZXing (pronounced “zebra crossing”) is definitely an open-source, multi-format 1D/2D barcode image processing library implemented in Java, with ports with other languages. Our focus is on while using built-in camera on cell phones to scan and decode bar code scanners around the device, without interacting having a server. Nevertheless the project may be used to scribe and decode bar code scanners on desktop computers and servers too. We presently support these formats:

UPC-A and UPC-E
EAN-8 and EAN-13
Code 39

Code 93
Code 128
ITF

Codabar
RSS-14 (all variants)
QR Code

Data Matrix
Aztec (‘beta’ quality)
PDF 417 (‘alpha’ quality)

This library is split into several primary components that are positively supported:

core: The core image decoding library, and test code
javase: J2SE-specific client code
zxingorg: The origin behind zxing.org/w

android: Android client, known as Barcode Scanner
androidtest: Android test application
android-integration: Supports integration with this Barcode Scanner application via Intent

You will find also additional modules that are led and/or occasionally maintained:

cpp: Partial C++ port
apple iphone: apple iphone client + port to Objective C / C++ (QR code only)
zxing.appspot.com: The origin behind our web-based barcode generator

csharp: Partial C# port
jruby: Ruby wrapper
actionscript: partial port to Actionscript

To enhance our decoding software, we’ve produced an internet-based QR Code generator which assists contact details, calendar occasions, Web addresses, plus much more.
