The barcode scanner has an automatic decoding and recognition capability. This allows the barcode reader to map the bars and spacing into the correct characters and avoid read errors. The accuracy of the recognition is very high with an error rate of only one in more than 3 million characters.

Yes, The barcode readers usually support many commonly used systems. Typically, more barcode scanners can recognize 1-D barcodes than 2-D ones. However, some of them can support several commonly used 2-D formats. Barcode scanners models from different manufactures support a variety of Barcode systems.

Although the 2-D code can be used to encode many characters, if necessary, the length can be changed to encode fewer characters. The amount of data in a variable-length barcode is limited by the number of symbols. The number of these depends on the capability of the barcode reader.

Nowadays, there are hundreds of available barcode symbol systems. However, only a few are widely used. Each of these ‘symbologies’ has unique barcode patterns, spacing modes, and data encoding rules. There are two basic types of barcodes: 1-D and 2-D barcodes. 1) A 1-D barcode is a one-dimensional line-type code with the data arranged in bars with spaces between them. The U.P.C./EAN symbol system is a typical 1-D barcode. 2) 2-D barcodes use another dimension to encode the data. There are two main types of 2-D barcodes: Stack and matrix type symbol systems. The stack type consists of many one dimensional symbols stacked over each other. The matrix type consists of blocks or lines formed by squares and geometric patterns. In addition, there are also hybrid type 2-D symbol systems and other variations.

The wide variety of barcodes allows you to find a suitable system to meet your requirements. If you want to make sure which barcode type is the most suitable for you, the key criteria are the amount of data to be encoded, the space available to print the barcodes and the data type to be encoded.
