Abstract
Advances in wireless technology support smart card technology became contactless technology. Wireless technology allowed users to access or controlling. However, existing contactless smart cards have limited coverage with low security levels. Therefore, this research perform optimization on user access further with better security assurance. This research implemented in classroom and laboratory access. Hardware that used consists of Smart cards and Raspberry Pi that serves as a host and card reader that could be interconnected with the microprocessor. On the smart card stored user data (registration number and name) and on the Raspberry server stored user data that could access the class or laboratory. User’s data on smart cards were stored on chips that act like RAM (Random Access Memory). The chip was embedded in the Smart card in the same function as storage media. Raspberry that had function as server and microprocessor that provide access to registered users. This study produced classroom access system by using smart card with distance > 5cm with automatic access system for user registered on system. It was according to this research proposed about security and historical data. Reader in this research use wireless transmission system. Historical data stored on the server (Raspberry pi) which records the time in and out, and the duration of time while in the room. Additional technology in the classroom access system is equipped with an automatic door close system for double security in the classroom. The advantages of this system was using server and microcontroller in one package so that in terms of cost is cheaper than the smart card access technology available today.
