It could be that a company just wants to have one (biometric) reader to lock the door to the server room. Or they want to be sure the staff that's coming in to clean the office every day is coming in on time and not switching cards.

Employees should be exposed early on to the technology, and though the systems are designed to be accurate, there are some things that take habituation. It's a good idea to have a very effective trainer.
