We're using QR tags at our office for the door locks sometimes. People with 24/7 access get more robust RFID tags, but for time-sensitive access, we just generate their key & print out a QR code with it that they show the camera.

This sounds like a neat setup - do you have anymore info on it? I assume it's custom and not off the shelf?

I don't have any info posted about the camera setup, but we're using a Windows laptop with some random QR reader (fastest one we found) to call the unlock URL on the Linux lock server sitting next to it w/the key from the QR code.

Here's a brief post I did on the lock system itself: http://adrianpike.tumblr.com/post/6009384439/door-locks-on-r...

Source is over on GH, but it would be pretty straightforward to roll your own nice & quick. If you do want to use mine, I'd be totally willing to help hack in new features, I've got lots of stuff I want to improve it with, but just don't have the side project time.

Do you have QR-enabled cameras at each door? Is it a custom solution?

Just one door, it's not that big an office. :)
