Design of access control system based on the near field communication (NFC) technology

摘要

With the development of mobile Internet technology, Android smart phones is gradually integrated into people's lives, and become important information terminal, Short-range wireless communication (NFC) is one of the technologies for use in access control systems, this kind of short-distance wireless communication standard can be achieved within a few centimeters of data exchange between devices. NFC is also in full compliance with ISO standards for management of contactless smart card, which is a notable feature of it an ideal platform. Android smartphones are gradually replace most of the commonly used tools in our lives, such as cameras, maps and so on, and NFC functionality based on the Android platform will gradually replace the life of cash payments and IC card access control system, NFC has become an important trend of development of intelligent access control system. This design from two aspects of hardware and software to take on Android platform-based NFC function plays an important role in access control systems. This design is based on the Android phone's NFC features using single-chip computer system relays, electromagnetic locks, smart home functions, NFC contactless door way humans bring more convenience, farewell forgot to bring my keys at home will not be suffering.
