A QR Code system is used in combination with a QR Code printer(or QR Code creation software) and QR Code scanner.

Use QR Code printers and PC software to print QR Code.

Choose from a full lineup of QR Code scanners designed for a variety of applications. Cellular phones capable of reading QR Code are being sold recently also.

QR Code is generated with QR Code creation software and a special printer.

However, these tools cannot automatically create QR Code that can be read correctly. In order to generate a properly readable QR code for the intended reader, the size (area) of QR Code is important.

The size of QR Code is decided by determining a symbol version, based on data capacity, character type and error correction level, and by setting a module size, based on the performance of the printer for printing or the scanner for reading.
