In this paper, we provide a assistive aid for visually impaired people. Finger print is the unique identity of any individual. From olden days till today it has been the symbol of uniqueness. This Finger print based door bell security system is implemented using Arduino technology. In this system the database the close circle of the visually impaired person is stored using the Finger print sensor as input. This provides them with highest level of security. When the current finger print matches with the database, they are marked as authorised and the name is being conveyed to the visually impaired. And if it doesn’t they are conveyed as unauthorised. In the software the finger print data, date & time of the entries are listed for future investigation. Thus, this system publishes the name of the one at the door step to the visually impaired person inside the house.
