In this paper, a security mechanism that incorporates remote multifactor authentication [MFA] for bank locker security and similar applications is presented. MFA requires authentication by multiple persons and to make the system customer friendly, remote authentication mechanism is designed and implemented. Similarly, a banking server which is always available is prone to be hacked easily. In the designed system, the server is built over a microcontroller and will be available only during the period of transaction. This system makes use of four factor authentication using RFID, Fingerprint, OTP and Password and a Django web server built on a microcontroller which is available only during the transaction. All these components are integrated with the Raspberry Pi using Python and also a website is designed with the help of Django and hosted using Ngrok service.
