At present the communications technologies tend to be wireless. RFID is one of those technologies, in which labels or tags are identified in a coverage area. There are many RFID applications such as emission bands of the signal; one of those is the access control that operates in high frequency (HF). Generally the procedures of staff access to the office or employment in educational facilities, companies, government institutions and industries are conventional and are affected by the time it takes the system to identify authorized personal, visitors, and entry and exit control of assets. To optimize these access systems, was designed, built and tested a prototype using RFID technology, through this technology the time and errors were minimized, as well as facilitate the traceability of the authorized personnel, of the visitors and the assets (equipment value) of the company. This article describes the experience in the development of the research project on the design of proprietary RFID protocol for access control; this technology can ensure reliable access to facilities where required high levels of security without need for sophisticated equipment or complex methods, and with a low cost of implementation.
