2D Data Matrix Reading


A Data Matrix code is a two-dimensional matrix barcode consisting of black and white square modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. Usual data size is from a few bytes up to 2 kilobytes.

The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters.

OMR + 1D + 2D + OCR

Some customers have ‘legacy’ OMR applications as well as Bar-code, Data-Matrix and OCR 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).
