QR Code Barcode Format

QR (Quick Response) codes are widely used for marketing purposes, website logins, document and material tracking, and a host of other applications. Encryption is one less common use, and QR code has also appeared on Dutch coinage and tombstones in Japan and Uruguay.

The code was developed by the Japanese company Denso in 1994. According to Denso, printed QR code that has been smudged can be restored to reflect the original data it contained.

QR codes do not contain lines, numbers, letters nor other roman characters. Instead, the data they contain is expressed by patterns of square dots on a white background. Data can be read both horizontally and vertically. The patterns are read and interpreted by Reed-Solomon error correctors.

Other features of QR code noted by Denso include:

Standard QR features that are supported by the Barcode Software include:

Need to export your QR code as a PNG or TIFF file, or to drag your code into Adobe Photoshop or Illustrator? The Barcode Generator can do all of these tasks, with print-quality dots-per-inch resolution.
