Remember CueCat, that strange thing that came along at Radio Shack a few years back? It read barcodes with a little scanner than sat beside your mouse (get it, cat, mouse, haha!). Other than the obvious spyware issue that you know had to happen with something like that, I thought it was a really good idea. I got one when they first came out and used it a few times. What was the problem with the doomed CueCat?
I think there were two problems, actually: you had to get the scanner and you had to have special CueCat barcodes to read. If I recall correctly, you could scan standard barcodes, but the CC’s codes would go directly to special offers and more.
So think of this: a webcam barcode reader. You hold a barcode in front of your webcam, it recognizes it (which wouldn’t be terribly hard to program), looks it up in a database, and whisks you off to a site. Companies could even hook their database entries to special offer for a fee (read: profitability) and have customers go directly to a special offer or something. And if it’s done right, you could just send the code into the database and not any personal or serial information. It’d be nice to have open-source freeware for it, too, but I might just be dreaming.
As is standard on the Internet, someone’s thought of this before. The CamKat software doesn’t seem to be available in many places now (I found a link to it here). I think it could really work if done correctly. Lots of people already have webcams, and it wouldn’t be that hard to use. But could advertising work if it wasn’t annoying? Hmm.
