I Drew This

I discovered the very useful QR codes the other day. They’re a bit like barcodes, indeed they’re a type of bar code, only not so bar-like as actual bar codes, which seem to be composed solely of bars. These are two-dimensional bar codes, whereas barcode barcodes are only one-dimensional (when you think about it).

The useful thing about them, as far as I’m concerned, is that there are readers available that you can run from your mobile phone. I never saw one of these for the one-dimensional barcodes. It would have been useful. But now these two-dimensional barcodes have a reader that works with your phone’s camera, so that, to me at least, is useful.

I guess also, they’re of limited functionality. But they’re still in the early adopter phase, in this country at least, so I’m prepared to think of them as very cool, until they’re ubiquitous, at which point they’ll become banal and old.

If you want to know what this says and have a popular brand of phone camera, there’s a reader here.

If nothing else, it’s fun for an hour, and would make for a cool avatar if you hate putting pictures of yourself in avatars.
