Generate Java QR-Code

The research of the two-dimensional barcode begins in 1993 in our country; Java QR-Code is one of the matrix barcode which are used widely today. The advantages of Java QR-Code can be understood from the following aspects. The density of the matrix barcode is much more larger than the linear barcode. The capacity of encoded information can be as large as 1850 uppercase characters, 2710 numeric or 1108 bytes. The capacity of Java QR-Code is several dozens of the ordinary linear barcode. If we have large information to encode and only have small space to do so, the Java QR-Code will be a very good choice. Most linear barcode can encode only alpha and numeric; the Java QR-Code can encode several kinds of information than the one-dimensional barcode. The information can be any of image, sound, characters, signature, and finger print. The language can be encoded by the Java QR-Code will not be limited by the difference of the language itself.



To better know the benefit of using two-dimensional barcode to encode information, we may have a look at both the linear and matrix barcode at first. We should know clearly about the difference of the two main kinds of barcode.
