Access Control Systems Overview
There are a variety of different features that you have with your business security system.
Keyless Swipe Cards
The cards are given to employees much like a credit card, the magnetic strip contains information about the cardholder. A card reader, installed on your doorway system reads the stripe and grants permissible access. This is a highly effective, simple solution for guarding entrance and exit to areas within your business.
Very common, however potentially the least secure method to protect an area. A business assigns a key code to each employ to obtain entry, and that is used to grant access. This method is common for areas within your office that aren’t frequently accessed or do not hold valuable assets
Contactless Smart Cards
These cards are able to grant secure access to an area without being touched to a terminal. This allows faster access authorization while still maintaining high levels of security.
This system uses unique biological information to grant or deny access.
Fingerprints - The most common method of biometrics is fingerprint scanners. They are a quick and accurate way of verifying identity. Typical fingerprint scanner false rejection rates average less than 3%, where false acceptance is rarely an issue averaging around .01%.
Retinal Scanners - Retinal scanners work to scan a user’s eyes. Retinal scanners have a much lower false acceptance rate than fingerprint scanners at around 1 in 1.5 million, making them one of the most secure methods of biometrics. However, one of the reasons businesses choose retina and iris scanners is because the false rejection rate is hovering around 0%. Despite being one of the most secure forms of access control, retina scanners are difficult for businesses to adopt because they are widely considered inconvenient and invasive.
Voice Verification – is the controlling of access to a certain area by matching a voice to a previously recorded template. Every voice has unique characteristics, and voice authentication is typically used to verify identity remotely.
In addition to the three most popular biometric security systems mentioned, there are geometric palm readers, facial scanning and many other biometric access control methods. These obviously vary depending on the level of desired security, employee privacy and costs.
