QR Code Reading
A QR code (abbreviated from Quick Response Code) is a two-dimensional matrix barcode consisting of black squares arranged in a square grid on a white back ground. It is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to efficiently store data; extensions may also be used. The information to be encoded can be text or raw data. The applications of QR code include document management, product tracking, item identification, time tracking, and general marketing.
A QR code can be read by an imaging device such as a camera, and processed using Reed–Solomon error correction until the image can be appropriately interpreted. The required data is then extracted from patterns that are present in both horizontal and vertical components of the image.
OMR + 1D + 2D + OCR + QR
Some customers have ‘legacy’ OMR applications as well as Bar-code, Data-Matrix , OCR and QR applications. Kern found that in some cases a camera based technology provided the most cost effective and flexible solution.
The range of reading devices available, combined with the flexibility of Kern’s software, enables almost all types of codes and reading logics to be read.
Within the Technical Support Team are specialists who have many years of experience and can quickly find solutions to customer’s reading requirements. On occasions, the team have been challenged to provide diverse reading solutions for example, codes printed with invisible ink or reading magnetic ink (MICR).
