Abstract: The increasing need for women's safety in public areas has provided the base for innovation in creating compact, efficient personal security tools. This paper explores an intelligent keychain device tailored and designed with a combination of various defensive and alerting technologies with applications specifically for women's safety. The input involves GPS and GSM modules integrated with the A9G board. It has a LiPo battery, which is fitted with a push button. A preset alarm would immediately be sent to contacts in case of emergency. Other hardware installed was the taser for personal defense and a buzzer, to ensure a sufficiently audible alarm. The system is programmed with information through a USB to TTL converter. The methodology used here was to couple hardware with software, monitor locations, and communicate real-time information to the emergency contacts. The GPS/ GSM modules are selected to allow for global coverage, and the push button allows easy usage in emergencies, so taser modules with a further number of added security features. It is designed to be compact yet cost-effective, consumer-friendly, and also available with a reduction in power consumption based on an efficient selection of components.
