Diseño e implementación de un sistema de control de acceso multinivel en base de receptores Near Field Comunication (NFC)

Abstract

Using technology Near Field Communication (NFC) applied to access control in different areas is proposed in this project as an alternative solution to security access control and flow of people, taking advantage the advantages offered by this technology with high security and communication speed. The access control system based on NFC able to direct users according to the system requirements, technology was performed starting with the analysis of important concepts of NFC technology, these concepts from the design of the network is created Access to exchange data between devices using short-range handsets, then the prototype is implemented and interconnects the access control system consisting of eight (8) NFC receivers using a network of microcontrollers, which processes the information acquired by NFC receivers to provide or restrict access to different users through their preset in different areas to a central device, where it is administered and the information acquired by the system is monitored by a control software which is displayed privileges all activity in real time. The control software is linked to a database where user’s personal information is stored with an NFC tag to each. Finally run performance tests and the results obtained with the implementation of the prototype are analyzed.
