If you're having a cool room installed, you shouldn't even think twice about having a monitoring system installed at the same time. These constantly monitor the status of your cool room and can be connected to several phones in order to provide a warning if anything goes wrong. Even though they represent an additional expense during the installation of your cool room, they can be of immense value to your business.

Hobby conferences and fan conventions need name badges. You need a quick, easy way to ensure that nobody who shouldn't be present is on site, and for security and insurance purposes you need to know who did and didn't turn up. They present some design challenges, though: what can you do to ensure that your convention badge is as helpful and usable as possible?  Arguably the most important element of a con badge is also the simplest: the member's name.
