An access control system (ACS) is a type of security that manages and controls who or what is allowed entrance to a system, environment or facility.
What is an access control system?
When we talk about a physical access control system, we’re usually referring to an electronic security system. They typically use an identifier such as an access card to authorise people to enter certain areas. And, as they’re capable of logging who accessed where and when, they can provide valuable data to help you track how your buildings and sites are being used.
A variety of identifiers for access control solutions
Access cards are still the most common identifiers used in access control systems. You present your card to a reader and, if all the conditions stored in the system are met, you’re allowed to enter.
There are other options to cards, however, and some offer higher levels of security.
The key identification methods are:
- Something you have – such as an access card or badge or another type of identification tag.
- Something you know – for example a PIN or password.
- Something you are – biometric identifiers such as your fingerprint or iris.
