In this proposed system the question papers will be sent to the examination centres in the electronically locked box. The box can be opened by authorized user only. The electronic box is password protected. We need to enter valid password using matrix keypad to open an electronic box. We also need to flash valid RFID Card. When the RFID Card & Password both matches, box will be open through the electromagnetic lock mechanism. This will help the management people to protect papers and to keep it locked and sealed safely. In this we are using Arduino Mega (Atmega2560) to process data. If user enters wrong password, alert SMS is sent using GSM Modem to authorized mobile number immediately. Regulated power supply is provided to all the units.
