Biometric access control is one of the most popular types of security systems on the market, and for good reason: it combines security and convenience in a way that no other access control system can.

Access control refers to the management of an access point, such as a door, turnstile, elevator, etc. so as to only allow entry to authorized users. While access control systems can be used for virtually any access point that uses an electronic lock mechanism, doors are the most common applications for access control telefon-guide.

Access control systems come in three types, based on:

1. What the user has (object-based):
The user must possess a specific object to be granted entry. Common types of object-based access tokens include:

Keys
Fobs
ID Cards
2. What the user knows (information-based):
The user must know a specific code to be granted france-ipad entry. Common types of information-based access codes include:

Password
Pass-phrase
PIN number
3. Who the user is (biometric-based):
The user identifies themselves with their own body using biometrics. Common biometric modalities include:

Palm vein
Fingerprint
Iris scan
Face recognition
Why Are Biometrics Used in Security Systems?
Traditional access systems have a critical vulnerability: objects and data can be shared or stolen, allowing someone other than the intended user to access the facility if they get a hold of them.

This may or may not not be a big deal depending on the level of security that is required.

For example, many coffee shops use a keypad on the bathroom door with the passcode (usually just four digits) printed on the receipt so that visitors aren’t able to simply enter, use the restroom, and leave without ordering anything.

Whether this is good customer service or not is beside the point. In this case, the thing that the lock is protecting (a public bathroom) doesn’t exactly require Fort Knox-level security, so a simple keypad works just fine.

However, such a security system is unfit for anything that requires more serious protection. The problem with passcodes is that, because they are just information, they can be easily shared and distributed among an infinite number of people — even if those people aren’t authorized.

Physical access tokens (such as keys, fobs, and ID cards) share a similar vulnerability: they can be easily lost or stolen, allowing whoever has access to the token to have access to the facility — regardless of whether the person accessing it is actually authorized.

Biometrics, however, don’t have this vulnerability. Because your unique biometric code is always with you, it is very difficult for anyone other than you to access it.

This is why, while not all biometrics are equal in terms of security, even some of the least secure biometric systems are still more secure than traditional security systems.
