傳統的門禁系統密碼掣並不安全容易破壞主要因價格便宜，易於安裝。 感應卡讀卡器的安全性較高，可以分為門禁一體化的控制系統單獨使用，也可以將門禁分體意味著讀卡器不能獨立使用，需要連接控制面板才能使用，安全性很高。讀卡器門禁系統可以通過指定的軟件連接到與電腦連接的RS-485或TCP / IP通信端口作為考勤報告。 而且還通過互聯網CMS系統集中管理，方便可靠。 讀卡器可以使用八達通卡，指紋和臉部識別來防止盜用。

The security of traditional access control is relatively low. It can be easily cracked mainly due to cheap and easy installation. The security of proximity card is relatively higher, it comes in as either an All-in- one integrated control system or as a Separate Control System where the card reader cannot be used independently, connection to a control panel is required but it offers better security. Access control system can be connected to computer through computer software via RS-485 or TCP/IP communication port and attendance report can be thereafter generated. Through the internet CMS system with central management, reliability can be achieved. Card reader can read Octopus card, fingerprints and recognize faces in order to prevent misappropriation
