When you think of door access control, you probably picture a security guard with a keypad or a badge. However, there are many different ways to get in, including proximity card systems, smartphones, and more.

  1. Proximity card

Proximity cards are one of the most common types of access control. A proximity card contains a chip that stores information about you and your passcode, and when you wave it in front of a reader, the reader detects this chip and unlocks the door for you.

Proximity cards are often used as employee ID badges or student ID cards at universities because they’re convenient to carry around and easy to use; just wave them in front of a reader!

  1. Biometric fingerprint, retina, and facial recognition

Biometric fingerprint, retina, and facial recognition are more secure than proximity cards because they don’t transmit data over the air. In addition, biometric devices can be programmed to require multiple factors of authentication. This means that if you enter your PIN code incorrectly three times, or if someone tries to force their way in by using an access card that doesn’t belong to them (for example), the system will require an additional step before granting entry.

  1. Smartphone apps

The most common type of smartphone app is the one that lets you control your door from your phone. If you have one of these, all you have to do is download it and log in with your credentials (typically a username and password), so it’s easy as pie!

However, these apps can be vulnerable to hacking if they’re not properly secured. That means they’ll need to be updated regularly with new security patches if there are any vulnerabilities found in them by hackers. In addition, because they require internet access on both ends (your phone and the door), they may not work well if there’s no cell reception in an area where someone needs access control installed–or if their internet connection goes down unexpectedly.

  1. Key fob, keypad or PIN code

The most common method is by using a key fob, which is a small device that you carry with you. The second most common method is to use a keypad, which is a pad that you press to get in. The third option is a PIN code (personal identification number), which can be set up by the owner of the door access control system and has its own set of advantages and disadvantages compared to other methods.

The biggest advantage of this type of access control system is that it’s easy for people who don’t want to memorize multiple codes or remember them when they’re outside their homes or businesses; however, there are some disadvantages as well: If someone steals your phone or tablet while it’s connected via Bluetooth connection, then they will also have access to all areas within range even if those areas aren’t theirs!

Door access control varies widely but there are different ways to get in


There are many types of door access control and they can vary greatly. The most common type is a proximity card. This is an electronic device that is used by employees to get into buildings or rooms, similar to the ones at grocery stores which scan your fingerprint when you want to pay for something. Biometric fingerprint, retina and facial recognition are also becoming more popular because they offer an added level of security compared with traditional keys or cards because there isn’t any chance someone could copy them without having access first-hand knowledge about how these systems work!

When it comes to security systems, including door access control or security metal detectors, or else, it is important that you have the finest and latest one installed and utilized across your property for enhanced safety and security.
