Today I went to the Technology for Marketing and Advertising show{.external} with little expectations, however I ended up in the Mobile Internet seminar. This is where I found that QR codes (which I had briefly investigated last week for a work pitch) are already usable and being used in the real world (although they are old news in Japan and China I hear – they are even on McDonalds wrappers there).

Example QR code.

The above is an example code – use it and I’ll know when you do because it is a text message to me, telling me how modest (awesome) I am. All automated.

The programmes I installed to test the QR codes on my Windows Mobile Orange SPV E650 (aka the HTC S710) were the i-nigma reader{.external} and the Quickmark reader{.external} both of which work really well if the QR is large enough (anything over an inch in print was fine – screen worked better but that defeats the object!).

The QR code can include all manner of information – popular uses I have seen include sending direct to mobile web pages, auto dialling phone numbers, short texts and even full sms messages with number and message! If you want your own QR codes you can create them for non-commercial use on the kaywa web site{.external}. hey also have an excellent reader{.external} on there, just one not compatible with my phone at time of writing.

So I will be pushing for these codes to be used more in my line of work and looking out for them and using them when I see them. Apparently current uses include on “Lost” posters, on the labels of England shirts and The Sun ran a piece on QR codes{.external} when they printed a code in the tabloid back in December.

Now I’m off to make QR code t-shirts – and you won’t know what they say unless you’re as cool as me and my phone!QR code
