Harry, Those are commonly called QR Codes. If you have a certain kind of app on your smartphone (the one I have is called Optiscan) and you aim it at one of those, it will take a "picture" of the code, which will (usually) send you to a website that contains information or a special offer from the business that placed the code. It essentially takes the place of typing in a URL.
These QR codes are the new shiny penny of technology that will change (yet again) the way we communicate forever. Actually, they aren't even all that new; they've been popular in Japan for several years. In my experience, it's usually faster to type in a web address than to search for the app, get it lined up correctly and then tell it to go to the website. I guess the one advantage is that you can save it to view later and you don't have to memorize a URL. I've seen them on a few realtors "for sale" signs recently. The other day I stopped at one of them to see what I'd get it if I used it. I got out of my car, walked up close enough for my phone's camera to be able to read it (if they'd just put the web address on there, I could have typed it in without leaving my car, but that would have been too 20th century) and got everything positioned properly, but the app said it couldn't read it. When I looked at closely I could see that the sign had been rained on and the ink that made up the lines in the QR code had smeared a bit, making it unreadable. So much for the latest technology. > I forgot to paste in the url: here it is > > > <http://www.racoindustries.com/barcodegenerator/2d/datamatrix.aspx> > > Have you seen those square barcodes that appear to be a jumble of lines.
