Abstract: A child or individual tracking system is disclosed. The system is equipped with at least one RFID tag, several RFID readers, a central server computer, and at least one mobile device. A mapped grid of RFID readers are deployed within a public space, such as an amusement park, and an RFID tag sticker is placed on the child to be tracked within the public area. Children are tracked in real-time via the system, and their whereabouts are displayed to parents or guardians via a mobile device application interfaced with the central server computer, helping to prevent lost children and kidnappings. User-defined zones are employed, which enable parents/guardians to be alerted when the child is out of the predefined range centered on the location of the parent/guardian.
