QR Codes

You may have noticed that I have added a QR code for mobile phones. It doesn't do much, other than allow your QR-enabled mobile phone to open this blog.

What is a QR Code?

I'll quote from Google's Chart API page:

QR Codes are a popular type of two-dimensional barcode, which are also known as hardlinks or physical world hyperlinks. QR Codes store text, which can be a URL, contact information, telephone number, even whole verses of poems!

QR codes can be read by any device that has the appropriate software installed. Such devices range from dedicated QR code readers to mobile phones.

QR code is trademarked by Denso Wave, Inc. As you'd expect, the Denso Wave website includes a lot of useful information about QR codes.

So, anyone can turn almost any smallish textual content into a QR code.

Making Them

You can make you own QR codes easily with this online tool.

Google also provides a handy services to create your own. You can add the URL to any web page as an image like I did on this blog.

Here are some more examples

A link to a web page:

Send an email to Bill:

Phone Bill:

Add Bill's contact details:

And don't forget Bill's birthday:'s+Birthday%0D%0ADTSTART%3A20090930%0D%0ADTEND%3A20090930%0D%0AEND%3AVEVENT%0D%0A
