This study aimed to develop a system that would monitor the vehicle entry to Letran Calamba campus using a Radio Frequency Identification (RFID) Technology. This project uses a gate barrier that would hinder the entering of vehicles in the colegio’s vehicle main gate for inspection and verification of RFID card. It opens if the vehicle owner has a valid RFID card to be read within the reader zone and displays the vehicle and owner information on the monitor as well as the date and time of the current log-in. If the RFID card is already expired, a message that says so would be seen, a red LED would light up, and the gate barrier would not open. Those who have no or expired RFID cards could still enter the school vicinity but only through manual operation of the gate barrier. It would be done by the security personnel in-charge and they will have to record information about them on the security personnel’s logbook. The system has also a database containing information of every vehicle which has a valid RFID card as well as its owner information.
