Smart Door Using Biometric NFC Band and OTP Based Methods

In this technologically evolving era, with the transition towards a wireless world, security plays a vital role in ensuring the safety. Over the years various methods have been proposed by researchers across the globe which has proven to be successful but have lacked in areas such as security and authentication time. This project presents an innovative design for a Smart door with the aid of a biometric, NFC band and OTP authentication methods which would provide secure and easy access to our homes. Our idea brings forth the opportunity to mitigate the issues faced by these systems by reducing authentication time with the help of a biometric fingerprint sensor and adds an extra layer of security using the help of a local server to generate OTP authentication. This implementation has shown better results and higher performance rate than existing methods. Here we are using RFID card as NFC band, for biometric we are using finger print sensor and for OTP we are using keypad. Here first we will place RFID card and it accept that then we have to give fingerprint then we have to give OTP then door will open.
