Ensure Your Security with a Biometric Access Control System — No More Codes & Keys

In an era where security breaches are not just a threat but a costly fact, installing an access control system is inevitable. A biometric system protects your sensitive data and premises using your unique physical characteristics. 

Due to advanced security, simple-to-use mechanism, and cost-effectiveness, it’s being spread around the globe. The worldwide market for biometric systems, as per an analysis from Grand View Research, had a valuation of 34.27 billion US dollars in the year 2022. It is projected to grow at a compound annual growth rate (CAGR) of 20.4% during the forecast period from 2023 to 2030.

What Is a Biometric Access Control System?

A security setup called a biometric access system uses special body features, such as finger patterns or face shapes, to decide who can get into a protected space or use certain devices. Think of it as an advanced lock that only works for those who have the correct ‘body password’. It’s like a high-tech lock that only opens for people with the right ‘biological key.

How Biometric Security Systems Function

As discussed earlier, a biometric access control system works with physical access rather than pin codes or keys. Following the given procedure, it operates:

  • Capture: A system grabs a picture or reads your biometric data, like your fingerprint when you touch a sensor, your face when you look at a camera, or your eye when you peer into a scanner.
  • Store: Afterward, your information automatically gets stored in a secured database or stored template for future use.
  • Compare: Now, when you want to gain access to something, the biometric devices will check whether your data is stored or not. In case your biometric credentials aren’t available in the system, you won’t get access.
  • Match/No Match: If the information matches, the system knows it’s you and grants access. It unlocks the door locks, logs you into your computer, or lets you access your bank account. If it doesn’t match, the biometric devices restrict access to you, just like if you didn’t have the right key for a lock.

Different Biometric Security Checkpoint Types

  • Since vein patterns are inside the body and not visible to the naked eye, it is tough to forge them.
  • Non-intrusive and hygienic than other biometric access control systems.
  • Low false acceptance and rejection rates

Cons 

  • More expensive than other biometric access control solutions.
  • Less integration with existing systems.

Advantages of Using Biometric Security

Using unique physical characteristics and individuals like facial recognition, iris scans, fingerprints, or voice recognition, biometric security systems operate to verify identity. This security method offers several benefits over existing access control systems methods like passwords or PIN codes.

Enhanced Security

Biometric data is much harder to replicate or steal compared to a password or a swipe card. It’s like having a safe that only opens with your fingerprint; only you have the unique key to unlock it. This reduces the risk of unauthorised access, making your data and personal information safer.

Easy to Use

Using biometric authentication, you don’t need to remember passwords and carry keys — your body is your key. Just a quick scan of your fingerprint or face, and you’re in. It’s a simple, one-step process to access your devices or secure areas.

Fast and Efficient

Since a biometric security system doesn’t require passwords and keys, it verifies your identity instantly, saving you time. This speed can be critical in busy airports or offices, helping keep things moving smoothly without sacrificing security.

Non-Transferable

The biometric access control devices ensure that only authorised individuals gain access since it can’t be shared, unlike a key and password. So, installing a biometric access system will ensure your security following a speedy approach.

Hard to Fake

With passing every single day, biometric access control systems are getting smarter and creating a high-security environment. They can identify the difference between a real person and a fake. For example, modern face recognition systems can detect if someone is using a photo, enhanced image, or a mask. This makes it much tougher for impostors to trick the system.
