Anyone received one of these funny looking bar codes on a QSL card yet?
The QR Code for my station site is shown below:http://home.roadrunner.com/~imageteklabs/n1foy/qr.jpg
You can read about them here:http://en.wikipedia.org/wiki/QR_Code
If your smart phone has a camera, there are free apps that you can download that read certain bar code formats. The beauty of this is you can launch your smart phone camera app and point it at the 2D bar code and it will instantly point your smart phone browser to the website associated with the bar code. You can generate the bar codes for free and include them on just about anything. My web cam also reads these and it can launch my PC browser and direct it to the site linked with the barcode.
Technology is getting more way cool every day.
