A member asked for input on this question: "What technology could be utilized to register employees leave a building, besides a card reader?" My answer was this:
"This question is a little thorny. First, the project needs to use read-in/read-out locking, which is not always an option per life/safety regulations. In many cases, hanging a PIN pad on both sides of the door with a camera hung adjacent was good for a multi-system documentation system. While PIN codes can be shared, the video integration helps check against this type of abuse. However, the best method of registering people while leaving meant using a supervised 'visitor management' program. We will talk about 'visitor management' towards the end of class, but it even those systems are more 'people management' than 'engineering controls'."
Your experience may be different and certainly more creative than mine. What do you think?
