What is Access Control Technology and how has it evolved

Access control basically refers to limited or restricted access to a place or a resource or an information etc. Access control is used in the fields like physical security in which a place is provided with access control so that not more than a pre-decided number of individuals can access the place. The access control technology is also used in the field of information security. The term access control refers to the practice of restricting entrance to a property, a building, or a room, or an online secured entity (bank account or website) to authorized persons.  By involving the access control in the field of information technology, the security of the information, data and transactions can be secured to a major extent.

The use of credentials in every type of access control is very important; it is the sole factor that makes the whole technology useful. A credential is a physical/tangible object, a piece of knowledge, or a facet of a person’s physical being that enables an individual access to a given physical facility or computer-based information system. . From a long time there have been physical credentials such as keys. Advancements in technology and in the ways from which a false access could be made, these factors resulted in advancements in credentials also. The concept of key cards (which is similar to keys), and a special password as credentials came in existence that was widely accepted. Today most of your data and information on internet (social media, websites, and bank accounts) is protected from unauthorized access by the means of password only. Recent innovation in technology has introduced access control that uses your biometrics as credentials. The biometrics can be your facial features, voice patterns, finger or thumb prints or even the iris or retinal scans. Fingerprint recognition is the most common biometric technology. It’s relatively simple and costs less to implement than other forms of biometric security. In some cases, multiple methods of biometric identification are combined for even greater security.

There are many advantages of using these innovations in access control. Use of biometrics is highly secure as to duplicate your unique anatomical features is not an easy job.  Biometrical access can be used in extreme environment, places where using or carrying a badge or key card is not very practical.

In the upcoming time, the access control technology is likely to be introduced with quite interesting innovations and advancements. An important and interesting innovation could be new form of credentials, a smart card, a wearable or a body implant (chip or any other circuitry) may show up. Judging by the improvement of wireless technology, wireless locks are likely to dominate the access control.

As security threats evolve and access control capabilities expand, the systems become increasingly necessary for a wide range of organization.  The integration and simplicity of access control is also likely to improve. The customer demand for integration increases. Integration implies the connection of various systems that may improve each other’s creativity. Today, customers are looking to integrate their access control with systems that include video management software, parking and gate management, human resources databases, license-plate recognition, and building control. More integrated and rich access control systems are likely to become more advanced.


Wi-Fi access control has already been around for a while, the technology is poised to truly take off in the coming years. Manufacturers are releasing Wi-Fi- enabled readers, electronic locks, panels, and door sensors or strikes, all of which communicate with each other and any central control software that the customer uses. Today ’s

Wi-Fi access control technology is growing ever more intelligent and  effective. New systems can even incorporate end users’ mobile devices as credentials, enabling your customers to do away with traditional PIN codes and cards in favor of using smartphones that most of their employees already take everywhere. Because these devices communicate using Wi-Fi and are battery-operated, installation is extremely easy and flexible. Customers can add a new access point to their network without the cost and time investment associated with conventional access control technology. Artificial intelligence is also finding its application in access control. Voice recognition, gesture recognition and facial pattern recognition are being perfected by incorporating machine learning and neural networks. As the access control industry continues to grow and evolve, we see several key trends taking shape that are likely to have an impact.
