Open Source QR Code Library

Open Source QR Code Library

What is QR Code ?

QR Code is one of two-dimensional barcode, used widely in Japan. The advantage of QR Code from well-known barcode is larger data capacity (more than 100 bytes, typically) and error correction feature.

Most of japanese mobilephone has embeded QR Code Reader. Currently, QR Code became popular interface which connects user and web sites in Japan. But decoder library was available only under fee based until this project was launched.

In other word, QR Code can be described as universal analog/digital (real/virtual) data exchange interface which requires very cheap cost. By this viewpoint, I think QR Code has big potential.

Project Summary

This project develops open source QR Code decode/encode library. The project goal is "Utilize QR Code embeded information for programmble devices all over the world". QR Code is the industrial standard, JIS-X-0510 and ISO/IEC18004.
