See an explanatory link here for mobile tagging. It describes the Japanese “Quick Response (QR) codes“, which are the pioneering and most widely-used codes, and the later European-US Data Matrix (DM) codes. Both are two-dimensional barcodes that a mobile phone loaded with a free app can instantly photograph and link to a Web page of information. The code being printed on Page 2 of The Age is a QR code. It is only 30 mm square, which is easily photographed. An automatic QR code reading app is easily downloaded from the Quickmark website to many brands of mobile phone and installed. The DM codes seem to be more geared to proprietary labelling, as they can be made very much smaller, but some users might prefer them, so both could be usefully shown.

Space on a standard corner of each sign should be kept for a QR code and, if thought fit, a DM code also, placed there initially or later. Web pages linked to could start as quite basic, but are easily enhanced. Each page could have a link to an Index of all signs, and a search box, so visitors could search for matters of their particular interest. Signs have no space for versions in the many languages non-English speakers might prefer, but Web pages can easily provide numerous languages, sound, videos, easy centralized updating, and user storage and forwarding.

Visitors will increasingly find that resource valuable. They can also save the Index Page link for later reference. A map showing signs with clickable GPS references could be useful. The website should have all the sign information anyway. Younger aficionados could well be motivated to show their prowess with the codes to their parents and friends, but cannot if the codes are not there. Below are a QR code symbol and a DM symbol for Bayside City Council’s website. The symbols were made with a mobile code generator facility, like Telstra’s by typing in the URL of the web page and saving the resulting QR code symbol as a .jpg file. Bayside Council has included mobile phone tags on its signs in Donald MacDonald Reserve in Beaumaris, and in Cheltenham Park.
