Door access authentication systems are essential to ensure that the right persons are entering your facility. The options that allow you to authenticate every entry made to your organization are not few.

Door access control systems at workplaces can include everything from entering specific numbers on a keypad placed at the main entrance to biometric authentication.

Each of these high-quality access control systems may offer a different level of security, can have different working mechanisms, and may vary in their prices. Here are the different types of door access authentication systems that you can consider for automated authentication:

Keypads: The most inexpensive door access authentication system is a keypad system that is attached to an electric lock. For a single door entry, most businesses use a lock that has a specific pin. However, this is not considered ideal for security reasons.

Card credentials: Another way of improved security is providing each employee a card or credential that has a unique number embedded in it. Previously such cards held bar codes and magnetic strikes for unique identification but these days cards with radio frequency identification type systems are available that carry an encrypted number.

Fingerprint authentication: There are several systems and a number of technologies that are available to read fingerprints. Fingerprint identification systems can use either a scanner or pressure-sensitive materials. You don't have to worry about your card getting lost or stolen. This is one of the most secured door access authentication systems.

Facial recognition: A facial recognition system depends basically on capturing and identifying your facial metrics. When employees are registered for this system a picture is taken that is later used for comparison at the door.
