For instance, for a full-time employee a key may be programmed to only allow access from 8am to 6pm Monday to Friday. An employee who works on Tuesdays will be given a key that allows access only on Tuesdays, and so on.
What if a contractor needs to be given access for one day? Simple! Just issue that contractor with an EKA key that is valid for that day only. The reporting system will tell you when they came and when they left. They won’t be able to return at night because their key won’t work.
