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 a JavaScript pop-up. # NDEF message: [00] D1 01 7D 55 00 64 61 74 61 3A 74 65 78 74 2F 68 …

iBeacon Business Cards

Four years ago, I wrote an article for Moo.com about using QR Codes on business cards. At the time, it was the easiest way to get VCARD information from a physical card and onto a phone. I notice that Moo are now selling NFC enabled business cards. As regular readers know, I'm not a great fan of NFC - mostly because it's so expensive. The NFC cards are £1.20 each - the regular cards cost just …

Various NFC icons.

Public transport is a great way to assess the Zeitgeist. Watching commuters transition from iPhones to Samsungs, and from paper books to Kindles, really gives one a sense of how the world is changing. Advertising is also a great way to measure society; seeing lots of adverts for dodgy loan companies can give you an interesting idea about the direction of the economy. I've been tracking the…

Clear Channel's NFC Mistake

· 7 comments · 300 words · Viewed ~908 times


I've talked before about advertising hoardings with combined NFC & QR codes. It looks like Clear Channel - the advertising behemoth - is getting into the game. Spotted all over London are these bus stops with built in advertising poster. Look on the right hand side, and you'll see the interactive element. It's pretty well designed, although the disclaimer "standard network rates apply"…

NFC In Las Vegas

· 3 comments · 450 words


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 me - there was an interesting use of NFC which I'd seen in Las Vegas. Las Vegas - like most of the …

A tiny packet of salt which has a QR code printed on it.

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. Some people prefer RFID/NFC. Others still prefer dedicated augmented video apps. As I've written many times before, QR codes have several substantial advantages over alternate technologies. QR is a free and open…

Can you spot anything interesting on this poster? Yes, there in the corner - living in blissful harmony are a QR code and an NFC tag. There's an excellent call-to-action which even works for people without either a QR reader or NFC scanner. The destination is this mobile friendly landing page. Of course, you should still boycott Nestle due to their contributing to the unnecessary death…

The Problem With RFID

RFID is like cold fusion. It will revolutionise everything - and it's only five years away! Terence Eden And, much like cold fusion, NFC will permantently be just around the corner. It's been "The Year of NFC" since 2008. Just like it was in 2009 and in 2010. Today the news came that Google may be abandoning QR codes in favour of NFC for its business places service. I think this is a mistake …
