Access Control Systems are an easy solution to manage physical access security. Once your Access Control System is set-up, you no longer need to worry about keys, and who has access to a room or building.
You can very easily set access dates and times for your cards, or certain cards. You will be able to give each card specific authorisation zones, and take them away just as easily.
If a card goes missing or is damaged, it will take a few minutes to issue a new one, taking away the hassle of replacing traditional keys.
