| Summary: | 碩士 === 明志科技大學 === 電子工程系碩士班 === 104 === In the early stage the access control system is implemented by means of mechanical lock technique. With the trend of digitization, magnetic cards and widely-used RFID techniques are utilized in access control systems. NFC (Near Field Communication) has gradually becomes a basic equipment for Android mobile phones, and there are more and more NFC-related applications for the access control system. In this thesis, we set up an access control system that mainly comprises three of portions. The first portion is that the reader utilizing Microchip processors together with FreeRTOS real-time operating system is applied to receive data from the server and NFC-based mobiles and to collect data form RFID Tag. For the second portion, the supervisor can retrieve the status of the reader or control it via the web server. In the third portion, NFC P2P data transmission between the NFC-based mobiles and the reader is performed. However, it would still take time for mobile devices to replace other contactless systems while implementing the access control system. Thus, we provide users with an access control system which possesses both features of NFC and RFID.
