QR Code & MS Tag Experiment


At Thursday’s technical community event I had a little experiment involving QR Codes and Microsoft Tags.  We have information up in our office meeting rooms about how visitors may access our wireless network.  We have an alphanumeric access key and I used this as the basis for my little experiment.

Next to each of the sets of instructions I put four images – each encoded the wireless key for the wireless network.

  • Black QR Code generated at QuickMark.
  • Purple QR Code generated at SnapMaze.
  • Colour Microsoft Tag generated at Microsoft.
  • Greyscale Microsoft tag generated in Paint.Net from the colour tag mentioned above.

Notably the two QR codes were radically different in structure.  Something I may look into further as I thought that QR codes should follow a standard encoding algorithm.

The aim of the experiment was to see how many people in this community (who had discussed QR codes at previous meetings) would spot and use the codes – at least just to see what they were.

With three sets around the room on the backs of all but one door I was expecting a bit of interest or someone to ask what they were for … and then get a little bit of pre/post meeting discussion about what these encoded images could be realistically used for (as there’s only a small benefit in encoding the network key – reduction in typos if you’re connecting your phone to the wireless network).

Through the whole day I heard no discussion and saw only one person snap an image – the purple QR code.

So it looks like the codes are still not pervasive enough in Western society to immediately cpature many people’s attention.  I think coloured QR codes are probably going to be the best way to grab people’s attention initially, but until (/if) it really gets embedded and on every mobile phone as standard it looks like it might be difficult to generate a huge amount of interest – even amongst technical people who have shown an interest in it.


Omnia and Microsoft Tag


Well it’s been a little while since I posted my comparison of Microsoft Tag and QR Codes.  In this post I noted that there was a strange 90° anti-clockwise when using the Microsoft Tag reader on my Samsung Omnia i900. Well I stumbled across the reason today whilst testing some Microsoft Tag print outs I had produced for an event.

Being a Windows Mobile 6 device, the Omnia allows screen rotation and even includes an accelerometer to aid in this (thogh I’ve disabled mine and assigned screen rotation to a button).  By now you can probably see where this is going.

When the screen rotation is in effect you effectively hold the Omnia in a landscape orientation like a regular camera and in this orientation the Microsoft Tag reader become a whole lot easier to operate.

I’d still like some sort of setting (or better yet ‘intelligent automatic feature’) in Microsoft Tag Reader to allow the Omnia to orient more easily when being held in portrait position – its normal phone position.


Zxing a QR Code in a pinch


Have you ever found yourself in a pinch where there’s a QR code on a web page or stored on your computer and you don’t have your phone with you (or more often than not your smart phone’s battery has died on you {again})?  Well Zxing to the rescue.

The Zxing on-line decoder allows you to specify the URL for a QR code or to upload one and it will display its details for you.

Really quick…

Really simple…

I really like it.
