#34: QRCode

My new phone (the delicious Nokia N95) has a feature on it called “barcode reader”. When I discovered this, I thought “great!” - although I didn’t see how scanning the back of a Nutrigrain packet to find out its barcode would be very useful at all, seeing as the number that the barcode represents is usually written across the bottom.

I think this is a brilliant idea, although I can’t recall ever have seen one of these codes anywhere else. They can encode quite a lot of information for a small image. I encoded some of my important data as a QRCode…
