Types of Access Control Methods
Types of Access Control Methods
One of the biggest differentiators between access control systems is how authorized users unlock the door. The type of credentials supported by the access control system affects the capabilities and security of design and factors into the system’s cost. Not all access control types can help, every type of credential
Physical Keys
The most basic form of access control requires authorized individuals to carry a metal key for each door they need to unlock.
Pin codes
With access control systems keypad reader, users have to enter a unique PIN code to unlock the door.
Key cards
One of the most common types of commercial access control, critical card door lock systems, use signals or code embedded in a vital card to authenticate users. Depending on the system, key cards can include a magnetic strip for swipe access control systems or use an RFID activated chip for a proximity door lock system.
Key fobs
A more modern credential for proximity and RFID systems, key fobs are small and convenient to use. Depending on the certificate’s type of security and functionality, key fob access control prices can range significantly.
Mobile credentials
With this type of access control, a user’s smartphone is their key. Usually app-based, mobile credentials allow users to unlock the door by tapping a button inside an app and often support additional access control methods such as Apple Watch and tablet apps. Mobile access control systems that use Wi-Fi, Bluetooth, and cellular data also can support touchless and proximity-based unlocking.
Biometrics
Biometric credentials are often using in access control systems in high-security spaces. Technology including fingerprint readers, facial recognition, and iris scanning are typical examples of biometric access control. Biometrics can also use as a form of two-factor authentication. They require users to present a key card, fob, or mobile credential and complete a biometric scan to unlock the door.
