Various NFC icons.

I've just got a set of wearable NFC tags, and I've discovered something interesting about the way data is stored on them. tl;dr Overwriting a tag can leave old data intact, and still readable. Here's the decoded memory layout of a tag with data written to it. In this case, a (failed) experiment at storing… Continue reading →

A red painted nail with a circuit inside it.

My fingers are now Internet-enabled. Well... sort of! My dexterous digits can now wirelessly broadcast URls and all sorts of other information. Here's a video showing how!

I'm not a big fan of NFC. I think it's an impractical technology except in very specialised use cases. Because it's so rarely seen in the UK I don't tend to post about it much. The Boy Whatley recently posted about his new favourite NFC toy - the Nokia MD-310 (catchy name, guys!). That reminded… Continue reading →

My first QR code post of 2013! I'm a long term fan of QR codes. I know some people don't like the idea of augmenting reality with specific tags for computer vision - but I do.
