Preventing removal of persons without an approved escort

摘要

A method for preventing the egress of a protected person (child) from a given region without an approved escort provides each child with an identifying RFID tag, and each approved person with an identifying RFID tag. A lock region is defined and scanned by a computer-based system which compares the RFID tag of the child within the lock region with a list of approved escorts, and maintains the lock region closed unless the child is accompanied by one of the approved escorts.
