Door Access Card: A Complete and Easy-to-Understand Guide
A door access card is a simple and modern way to control who can enter a building, office, or secure area. Instead of using old-style keys, a person just needs to tap or swipe the card on the machine to open the door. It is easy to use and saves time.
Nowadays, door access cards are commonly used in offices, hospitals, hotels, and housing societies. They help keep unwanted people out, protect property, and maintain proper discipline. Because of its simplicity and safety, the door access card system has become a trusted security solution.
What Is a Door Access Card?
A door access card is a plastic card that uses smart electronic technology like RFID or proximity chips. Each card is linked to one person, so the system always knows who is trying to enter.
When a person taps the card on the reader near the door, the system checks their access instantly. If they are allowed, the door opens. If not, the door stays locked.
In simple and easy terms, a door access card replaces normal keys with a smarter and safer way to control who can enter and leave a place.
How Does a Door Access Card System Work?
The working of a door access card system is smooth and fast:
- A user taps or swipes the access card on the reader
- The reader sends the card data to the door controller
- The controller checks access permission in the system
- If permission is valid, the door unlocks
- The system records the entry or exit time
This entire process takes less than a second and does not require physical contact, making it hygienic and efficient.
Types of Door Access Cards
Different environments require different levels of security. Common types of door access cards include:
RFID Door Access Cards
These are the most popular and widely used cards. They work on contactless technology and are reliable, durable, and fast.
Proximity Cards
Proximity cards work when the card is brought close to the reader. They are ideal for offices with frequent movement of staff.
Smart Cards
Smart cards offer higher security with encrypted data. They are often used in corporate offices, data centers, and sensitive areas.
Magnetic Stripe Cards
These cards need to be swiped. They are less secure and are slowly being replaced by RFID and smart cards.
