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:
- High data capacity;
- The ability to be read from 360 degrees, in some cases;
- Smaller size; and
- Compatibility with written Japanese characters.
Standard QR features that are supported by the Barcode Software include:
- Free text input mode with error detection;
- Symbol dimension customization;
- Automatic and manual QR Code resolution; and
- Customizable front and back colors with spot color support for EPS file export.
