Code What is it? A machine readable two dimensional code such as the Barcodes you find on everyday packaging. Each Barcode contains and can display information. Most people are familiar with seeing Barcode readers in supermarket check-outs. The Barcode is only one of several different code formats. Semacode, QRcode Target and Aztec are other code formats
Creative Code How does it work? Codes contain information which can be read or scanned by barcode readers. Barcode readers are applications that can be put on devices such as mobile phones. The data or information can be gathered and exchanged. Potential uses for code tags are still being explored.
Code Potential uses As tags on posters, such as those for concerts and public performances. Those interested could use their mobile phone to read/scan the tag and link them directly to a web site where they could find out more about the event. The use of tags scanned by mobile phones could provide a body of text that was fragment of a poem or story. A person would have to seek for clues to find and scan other codes to collect all the parts together and complete the poem or story. A scanned tag at a specific site could display a photograph of that same place taken 100 years ago. Tags on clothing accessories could display information about the owner As a part of a design on an item of clothing
Code Data Matrix code is a two-dimensional matrix barcode consisting of black and white “cells” or 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 A Data Matrix symbol can store up to 2,335 alphanumeric characters. Error correction codes are added to increase symbol strength: so if damaged , they can still be read.
Creative Code Data Matrix 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 provides a count of the number of rows and columns in the symbol. As more data is encoded in the symbol, the number of cells (rows and columns) will increase. Symbol sizes vary from 8×8 to 144×144
