Two Dimensional Barcodes

QR Barcode

A QR Barcode is a two-dimensional Barcode that consists of a grid of dark and light dots or blocks that form a square. The data encoded in the Barcode can be numeric, alphanumeric, or Shift Japanese Industrial Standards (JIS8) characters. The QR Barcode uses version from 1 to 40. Version 1 measures 21 modules x 21 modules, Version 2 measures 25 modules x 25 modules, and so on. The number of modules increases in steps of 4 modules per side up to Version 40 that measures 177 modules x 177 modules. Each version has its own capacity. By default, the Barcode control automatically set the version according to the length of the input text. The QR Barcodes are designed for industrial uses and also commonly used in consumer advertising.
