Abstract
In example embodiments, a system and method for tracking a child using RFID is provided. A first reader detects a signal from the trackable device. First positional data of the trackable device is determined from the signal. The first positional data indicates a first direction of the trackable device relative to the first reader. Second positional data is received from a second reader. The second positional data indicates a second direction of the trackable device relative to the second reader. A location of the trackable device is calculated using the first positional data and the second positional data. The location is presented on the first reader.
