QR Code

QR Code is one of very few barcode types that allow encoding of Kanji and Kana.

An example:

Statistics

The symbol size of the QR Code is 21 x 21 modules to 177 x 177 modules corresponding to Version 1-40, increasing in steps of 4.
The numeric data is maximum capacity 7089 digits.
The alphanumeric data maximum capacity is 4296 characters.
The byte data maximum capacity is 2953 bytes.
The Kanji data maximum capacity is 1817 characters.

Error Correction Level

This barcode type uses a Reed-Solomon error detection and correction scheme. There are four levels of error correction, each with increasing amount of error recover. Note: The higher the error level, the less data that can be stored in the barcode.

"L" - 7% error recovery
"M" - 15% error recovery
"Q" - 25% error recovery
"H" - 30% error recovery

Caution: When using trial (unpaid) licensing, the words " UNLICENSED accusoft.com " will appear in every Data Matrix, QR Code and PDF417 barcode created, taking up 25 bytes of space including the leading and trailing spaces. When testing the contents of generated barcodes, be aware of the extra space requirements.
