ZXing is an open-source, 1D/2D barcode image processing library implemented in Java. The supported barcode formats include UPC-A, UPC-E, EAN-8, Code 93, Code 128, QR Code, Data Matrix, Aztec, PDF 417, etc. Besides the Java version, developers can leverage other ported projects such as QZXing, zxing-cpp, zxing_cpp.rb, python-zxing and ZXing .NET to quickly make barcode reader or writer software. According to the visualization report of Google trends, QR code seems to be the most popular barcode format since 2009. In this post, I’d like to share how to use ZXing to create QR code writer and reader for both desktop Java applications and Android mobile apps.
