You see QR Codes everywhere. Advertisements, marketing materials, commercials, and even billboards in the airport. Generating your own QR Code is a free thing to do online. The cool thing is to use a service that tracks your scans and provides metrics. Microsoft Tag has recently announced it is migrating to the ScanLife platform within two years. ScanLife will provide 3 personal QR Codes and tracking for 500 scans for free. I use QR Codes on my resume and they can point to anything - Picture, Video, Website, Cloud Content, Blog, etc.
