The PRO version includes a feature that allows a room's schedule to be accessed simply by scanning a specially crafted QR code. This makes it easy for users to check a room's availability without knowing any of the room's details such as its email address or name.
The QR code only needs to contain the email address of the room. There a many online services that can generate QR codes. One example is http://www.qrstuff.com/.
The QR must be configured to contain TEXT. The text should be the email address of the room you wish to access e.g.
If you want to also includes the room's name, you can add it by using a pipe character e.g.
Once a QR code has been scanned, the status of the room will be loaded. You'll then have the option to add the room to your list if it's not already present. This is useful for visitors from different regions that may not care about the status of a particular room once they leave their current region.
