Cos’ Blog QR Code?


You might be wondering what a QR Code is, you might even have seen them around in stores and in advertisements and just didn’t know what they were. I found a place online that generates QR Codes for free and I figured I’d make one for this blog.

Just so you know specifically what a QR Code is and how it works, here is what they are, as described by


A QR Code (it stands for “Quick Response”) is a mobile phone readable barcode that’s been big in Japan forever, broke into Europe a while back, and is now getting traction in USA.

In its simplest sense think “print based hypertext link” – simply encode a URL into the QR Code and then point a mobile phone (or other camera-enabled mobile) at it. If the device has had QR Code decoding software installed on it, it will fire up its browser and go straight to that URL.

But it doesn’t stop there – a QR Code can also contain a phone number, an SMS message, V-Card data or just plain alphanumeric text, and the scanning device will respond by opening up the correct application to handle the encoded data appropriately courtesy of the FNC1 Application Identifiers that are embedded in the encoded data.

And here is the QR Code for Cos’ Blog, doesn’t really do too much here, seeing that the code directs you to this exact website, but if you see a code somewhere and you use your smartphone it’ll send your smartphone to whatever was encoded on the other end.

Now, if you don’t already have an app that can read/scan QR codes, might I recommend Red Laser, I use it on my iPhone and it does a pretty good job. Let me know if you have any thoughts or suggestions.
