A quick response to QR and Data Matrix code.
So lately I have been seeing more Data Matrix and QR code around. Data Matrix and QR code is a 2D barcode consisting of black and white "cells" or modules arranged in either a square or rectangular pattern that represent encoded information. Unlike augmented reality markers, data matrix code only represents text or raw data. Data Matrix (DM) symbols are rectangular in shape and usually square, they are made of cells: little elements that represent bits . Depending on the situation a "light" module is a 0 and a "dark" module is a 1, or vice versa. Every Data Matrix is composed of two solid adjacent borders in an "L" shape (called the "finder pattern") and two other borders consisting of alternating dark and light "cells" or modules (called the "timing pattern"). Within these borders are rows and columns of cells encoding information. The finder pattern is used to locate and orient the symbol while the timing pattern p...
