Opening doors using a card is a convenient and secure way to enter buildings, homes, and other secure areas. This technology uses radio frequency identification (RFID) or near-field communication (NFC) to transmit data between the card and a reader, which then unlocks the door.
Card access systems offer several advantages over traditional key-based systems. They are more difficult to duplicate, providing enhanced security. Additionally, they can be programmed to allow or deny access to specific individuals or groups, making it easy to manage who can enter a particular area. Furthermore, card access systems can be integrated with other security systems, such as video surveillance and alarm systems, providing a comprehensive security solution.
