Objectives: To obtain a classical tracking device for helping common people with the aim of providing security and precaution. Methods: Multipurpose tracking system allows to track different types of people namely children, women and elderly people by insisting three buttons one for children, other for women and another for elderly people. These system alerts the receiver end people by using signals of GPS and sending message and calls through GSM and GPRS. In this work, voice recorder and a camera is initiated to know the actual situation in the front end as an image through email and voice through speaker. Findings: To tackle the above problem and safeguard them, we have found a small device in a locket model with advanced technologies like GPS (Global Positioning System), GSM (Global System for Mobile Communication), GPRS (General Package for Radio Service) which helps to track them latitudinal and longitudinal directions through satellite where the alert message and calls through voice playback are send to the receiver end like parents, police control room and attender and a camera which helps in taking visual images and send to the receiver end through email at the time of risk.
