In today’s real time modern industrialized world security systems place a vital role. Bank security is important for a number of reasons; one of those reasons includes providing secure banking for clients and protecting the bank from fraudulent behavior. This bank security system is mainly designed to meet the requisite of the security of valuables things (jewels) which are hard earned. Unlike the present system involving the physicals locks which can be easily forged this has the main feature of biometrics, which will open the door automatically whenever the series of authentication is verified and gives alert sounds when any mismatch occurs. In this system, microcontroller continuously monitors the sensors of the biometric system and RFID reader for the authenticated codes and the output of motion detector. The motion detector and microphone will be active during nights and if any variation occurs in its output, it will be sensed by the microcontroller and send message to the manager’s mobile phone also an alert sounds will be given by it. Using ESP8266 the bank security system can be monitor over the internet.
