The Evolution of Access Control Systems

Tuesday September 7, 2021

Access Control Systems detect, authenticate, and approve a person’s access to the premises. This provides comprehensive protection and assures the system’s security.

Access control systems are quickly evolving, both in physical contexts and in devices such as smartphones.

The Access Control System is itself a hot topic right now. But how far has technology already evolved? Pretty sure that is one of the most critical questions regarding the control system.

Are you worried that you aren’t using the latest Access Control System? Read to the end, and you’ll know for sure!

1. Simple keypads

Simple Keypads were the very first step in the Access Control System. The methods we use to access restricted places have evolved throughout time, and it all began with the renowned keypad.

These were used to access-locked locations that required an individual to key in a particular number password. This is similar to what we currently see on ATMs. And, for further security, the pin is typically four to six digits long.

It was a groundbreaking notion at the time, but it wasn’t very accurate. After all, anyone who acquired the code – possibly by peering over someone’s back – could also enter.

2. Card Readers for Access Control Systems

Recognizing the limitations of keypads, producers designed card readers. Typically, the creators affixed magnetic strips to the card. A staff member would then obtain entry by swiping it through a small hole.

Cards have become increasingly complex, with barcode, proximity, smart card, and biometric readers. Of course, each does have its unique advantages and disadvantages for various commercial uses.

Originally, the Card Reader system had many security issues as anyone who had gained access to the card could enter the secured area.

3. IP readers

IP readers were eventually added and could be retrieved through various methods. These include scanning a card and, more recently, Bluetooth-enabled smartphones.

These readers now widely use Biometrics for maximum security.

In addition, IP door readers, which perform a controller’s job, are sophisticated readers with the judicial authority to unlock the door.

They do not require access to the network to reach a central control panel through cables. Using authentication and authorization allows management to deliver security services by using innovation.

However, a power shutdown or malfunction can cause the whole system failure.

4. Smartphone for Access Control Systems

Smartphones are one of the fastest and most customer-friendly innovations in the world. Indeed, their role in Access Control systems is just as important.

Apple first introduced Touch ID in 2014, which took over the world like a storm. Soon, everybody started using fingerprint security systems to manage their mobiles and secure services.

In 2017, Apple included facial recognition with the iPhone X, with a 3D sensor recognizing the user’s facial features.

Still, fingerprint reading, Bluetooth connection, or even simpler PIN codes comes at a cost. It simplifies accessibility not just to the authorized user but to a potential attacker.

So always seek the counsel of an expert security installer when locating an access control system. After all, experts can guide you to a system that delivers a high level of protection.
