Card Reader Access Control: How Do RFID Systems Work?

For anyone considering a card access system, the most common question is how card readers work and which type fits their property.

How Does a Card Reader (RFID) System Work?

When the RFID card or fob assigned to each user is held near the reader, it transmits its unique ID to the control panel; the panel checks whether that ID is authorized, opens the door, and logs every pass with a timestamp.

Mifare or EM Card? Which Is More Secure?

EM cards are economical and widely used but more vulnerable to cloning; Mifare cards, which use encrypted communication, are much harder to clone and are preferred for offices and corporate buildings where security is a priority.

What Happens If a Card Is Lost?

If a card is lost, its access can be revoked within seconds from the management software, and a new card can be issued to the user without affecting the rest of the system.
