The list of technologies that can be used for people tracking keeps growing longer and longer. Techniques include artificial intelligence, biometrics collection, 3D spatial learning (augmented reality), video analytics, thermal imaging, structured light and laser scanners, open-source Raspberry Pi, WiFi, ultra wide band, radar imaging, bluetooth beacons, GPS, personal trackers, RFID tags, QR codes, and near field communication.

Cellular Tracking
Most people understand that when they carry a cell phone, they are being tracked. Not everyone understands to what extent. As seen below, the cellular network serves as a perpetual people tracking system.
