Personal Safety Tracker

Overview

Description

Keeping track of our belongings and loved ones is vitally important. Imagine embedding a tracker into clothing to achieve this. For instance, shoes are an integral part of our daily lives, and integrating safety features into them could make them even more valuable. Parents, in particular, are often concerned about their children's safety. A tracker embedded in a child's shoe can help parents stay informed about their child's location. Additionally, an integrated SOS alarm or information system can be a lifesaving tool in emergencies, instantly sending the location and alert. Wired or wireless fast charging options are also available.

System Benefits​:

  • SOS emergency alerts using GSM and GPS for precise location tracking
  • Low-cost, low-power system
  • Wireless charging option for fast, contactless charging
