There is a growing demand for such automated systems, which carry out their tasks without human supervision. Such systems include the family of access control systems, whose basic idea is, that some control points (eg, doors, gates, etc. dots) can only be bypassed by qualified persons. In such cases, a common solution is to set up an RFID based access control system. During the preparation of my thesis, I reviewed the potential entry methods, I introduced the RFID technology, compared the different data storage options, chosed the channel of communication with computers. My main task was to design and create an RFID-based access control system's hardware and software. During the selection of components I considered different opportunities, and choosed the best for my purposes. The system is composed of a central unit and several remote units, which communicate (for synchronization purposes) via radio signals. Each of the remote units are capable of autonomous operation, since the required data is stored in the unit's own database. We need the central unit only for database maintenance.
