QR Code Bar Code reader encode encoder decode decoder

QR Code Bar Code reader encode encoder decode decoder

ZXing - 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.

zxing-iphone - The iPhone4 camera is more than capabale of doing barcodes. The ZXing (zebra crossing) barcode library has a fork on github zxing-iphone. It's open-source.

ZBar bar code reader - A comprehensive software suite for reading barcodes. Supports EAN/UPC, Code 128, Code 39, Interleaved 2 of 5 and QR Code. Includes libraries and applications for decoding captured barcode images and using a video device (eg, webcam) as a barcode scanner.

Big in Japan - (disclaimer:me) has recently made their SDK available. And it's free! Check out

RedLaser SDK - There's another option for this now if you are open to licensing an SDK. Check out the RedLaser SDK that works for UPCA/EAN13 with or without autofocus. Recently updated.

PHP QR Code - is open source (LGPL) library for generating QR Code, 2-dimensional barcode. Based on libqrencode C library, provides API for creating QR Code barcode images (PNG, JPEG thanks to GD2). Implemented purely in PHP.

File2QR - is an Android app that let you encode any small file on the filesystem to a QR code. Conversely, you can decode the encoded file from the generated QR, with mobile's camera. File2QR is built on ZXing library.

libqrencode - is a C library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and is highly robust.

StripeReader - The library can recognize barcode1-D and 2-D. StripeReader was improve from Zxing.
