Development of a Quadruple Security System Combining Keypad, Rfid, Fingerprint, and Bluetooth Modules

Today, the security problem is emerging as a crucial problem for people, and research into solving this problem is now on its way worldwide. Everyone is aware of the urgency and seriousness of the security problem, and at this time, this problem has a giant impact on the overall social life. As science and technology develop, researches for solving security problems are advancing to a new stage, and their reliability is increasing day by day. In this study, a powerful quadruple security system was designed and realized by combining Keypad, RFID, Fingerprint, and Bluetooth (HC06) modules to thoroughly secure the security of medicines, jewelry, documents, and other valuables and doors. This system is based on the Arduino Mega 2560 microcontroller and is an intelligent system with a display function, voice function, SMS transmission function by GSM module, and alarm function. The system is an excellent system that can thoroughly guarantee the safety of security with low cost and low power consumption.
