As trivial as it sounds there is a quickness to QR Codes that make them so handy. While hiking in Italy we didn’t know where we were exactly but we came across an old sign which told about the area; however, it was too worn out to read. In the corner was a QR Code that we able to scan and get a ton of information about where we were.
Here is a link to a site I used to generate some QR Codes for my companies various division contacts.
I hope this helps someone else out there….
