What's all this about

The other day I noticed a lad walking through town with a tee shirt emblazoned with something similar to

I thought it was rather odd but not having my camera with me (unusual, but there you go) I was not able to record his pattern.
Then before throwing out a recent newspaper I notice that you can get an AP , presumably to read said square.

Queries-
Is this a new phenominon - why
Is there a PC based AP that read the same from DSLR pics

If you scan the bar code with your iPod it will download the app. It's just a barcode so in theory you could use the same technology for anything you wanted.

That's the gist of my second question. I mobile is a simple send and answer - no camera screen other than a number display or any other hi-falluting gizmos

QR codes contain around 100 bytes of data and most mobile devices with cameras can decode them if they are part of the image. Not so sure about software that can decode them from an image on a non-mobile sort of system like Windows - it must exist but isn't so useful.

*edited to add* this probably does the trick but I haven't tried it - http://techie-buzz.com/softwares/read-qr-codes-on-pc.html

Thanks all,
And Thanks for the link Karma - I've downloaded the prog and it runs quite easily.

The example above simply provides a WWW.xxxxxxxx address for a well known food supermarket.

I wonder what was on the lads tee shirt - I'll probably never know

Recently had an advertising leaflet from Opel trying to flog me cars - except to find about the cars I needed to scan the QR code. Since my phone doesn't even have a camera on it let alone internet it was a waste of paper. Not that I wanted to buy one of their cars anyway.

When you check in online you can have your boarding pass sent to your smart phone - I believe they use QR codes for those.

Can you buy a Game for the iPad called "Name that Barcode!"

Why? You can't be that desparate can you?

Whats an iPhone?

Are we all lemmings and follow the apple logo?

I'm not. I own nothing Apple.

I do. Some of their products are outstanding.

I wonder of anyone has seen the latest Apple lock down. New iMacs use a proprietary SATA connector for the HDD and a proprietary firmware which means the hard disk cannot be upgraded without going to Apple for an Apple specific version. If you replace it the cooling fans run at full pelt and screech.

Seriously, non-upgradable hard disks just takes the biscuit.

I saw this, apparently it is a standard SATA connector and you can fit non Apple drives. You just need to know how to do it correctly ...

Vic.

It's indeed just a SATA connector but it has 2 more pins for temperture or something like that...

You can get the BarCode app for Android to read QR, and UPC, barcodes.

And a link like this will build a QR code for you http://chart.apis.google.com/chart?cht=qr&chs=150x150&chl=http://layingback.net/... width="166" height="166" frameborder="0" scrolling="no" (I'd hotlink it, but this site doesn't seem to handle spaces in url's.) This one is just a link I use to my website.

You can pack a lot of data into a QR, but as you add data the resolution required goes up reducing the number of mobile phone cameras that can resolve it easily. But they are very useful for retrieving apps from the Android Market eg. If you find an app on your Personal Confuser then you can scan the supplied QR code with your phone's camera and it will download the app without any typing.
