Development of an RFID based access control system in the context of Bangladesh

Radio Frequency Identification (RFID) technology utilizes the electromagnetic fields for data transfer in order to perform automatic detection and tracking of tags or tags of objects. It can provide ways to design and implement relatively inexpensive systems particularly for security aspects. In this paper, we have proposed a digital access control system that can be employed to a protected area where none but people with authenticated credentials can enter. In fact, we have implemented the system in the server room of an educational Institute to test its efficiency as well as expenditure. The implemented system comprises of digital door lock which is unlock able in real time to ensure secured access specifying activation, authentication and validation of users prior to bringing the RFID card close to the reader. The entire system is associated with a central client-server sub-system to ensure and maintain the overall system integrity. Associated sub-system also generates a log report to maintain check-in and check-out status of visitors in accordance with the primary credentials of each. This system will certainly provide an idea about the design and installation of a relatively inexpensive security system which is suitable in the perspective of a developing country like Bangladesh.
