Access controls system provides the correct accesses as have been programmed. In case of a car, an access control system allows the user with the key or code to gain entry. Where this code is not available, the car will emit a sound and flashing lights to indicate that an intruder is lurking around.
The access control systems are what makes are safe and secure.
Types of Access Controls Systems
Physical access control system: Physical access control systems are where the keys were used. The keys and locks were the access control system.
Electronic access control systems: These utilise the information technology to regulate, record, monitor and deter accesses. They are augmented with alarm and cameras as well as the real-time recording of events for future references. Current modern systems employ computer.
Types.
There are unlimited access control systems. These systems generally control our lives. The could be the car alarm system, house security system, credit and debit card usage system , ATM withdrawals system, computer access system, email access systems, etc.
How they operate.
The electronic access control system uses a predetermined code to enable the owner of the code to request access.
Bank withdrawals: You can only access your account through the writing of a cheque to be withdrawn over the counter. The first security system is confirm the cheque leave issued by your bank. The next is you signature. A further verification is done by checking your identification documents and confirming that it is actually you who is the owner of the bank account.

Computer access control system: In case of a server or a safe vault, access control is compartmentalised. Here, over and above the credit system access control system mechanism, an additional dimension can be placed. In cases where you have forgotten a password. the system may issue you with a preset security questions which is hard to answer. Further, newer system solely allow for biometric scanning of retina or fingerprints. This way, they authentic the owners of the password. In case where one appears stressed, it will refuse to open sensing a compromised situation.
