A smart door access system using finger print biometric system

摘要

Previously, for high security areas or in locker rooms for banks, traditional lock systems, passwords, etc., were employed. However, these systems were found to be not perfectly secure. After advancements in technology RFID cards were used. These cards however were not much useful for the user due to chances of getting lost, stolen and forgotten. The purpose of this study is to provide high security for such high end security applications. The aim of this study is to design a smart door access system using finger print module. The use of this device is to provide access to only authorised persons. Both hardware and software technology are used to design it. An emergency beep sound is provided to protect the system by giving alarm if any unauthorised person intrudes into the system. An indicator indicates for any emergency condition. Motors are used for locking and unlocking the door.
