RFID and GSM Based Three Level Security System

Abstract

Security is an integral part of our life, be it personal or providing it for our belongings. Constant technological advancements have been made in the field of developing security systems over the past few years. 'Radio frequency identification' (RFID) and 'Global system for mobile communication' (GSM) are a few fields in which security systems have propelled to new heights. RFID has been used widely for database management in places like malls and office areas. GSM is also used as a medium of interaction between the customer and back end devices in various fields. Our project is the first of its kind which brings together these popularly used systems in developing a three level security system. To give a complete overview of our project, the individual needs to have the pre-defined card, an RFID tag and a mobile phone whose contact number is given beforehand. Thus there are three levels of security for the secured place.
