ZXing ("Zebra Crossing")

ZXing (pronounced "zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. Our focus is on using the built-in camera on mobile phones to photograph and decode barcodes on the device, without communicating with a server. We currently have production-quality support for:

• UPC-A and UPC-E
• EAN-8 and EAN-13
• Code 39
• Code 128
• QR Code
• Data Matrix ('alpha' quality)
• PDF 417 ('alpha' quality)
• ITF

This library is divided into several components; some are actively supported:

1. core: The core image decoding library, and test code
2. javase: J2SE-specific client code
3. android: Android client, called Barcode Scanner
4. androidtest: Android test app
5. android-integration: Supports integration with our Barcode Scanner app via Intent
6. zxingorg: The source behind zxing.org/w
7. zxing.appspot.com: The source behind our web-based barcode generator

Some modules are contributed and/or intermittently maintained:

1. javame: JavaME client
2. csharp: Partial C# port
3. cpp: Partial C++ port
4. rim: RIM/Blackberry-specific client build
5. iphone: iPhone client + port to Objective C / C++ (QR code only)
6. bug: Client for BugLabs's BUG

New: To complement our decoding software, we have created a web-based QR Code generator which supports contact information, calendar events, URLs, and much more.

QR code is trademarked by Denso Wave, inc. Thanks to Haase & Martin OHG for contributing the logo above.
