Physical assets are a firm, government, or individual's most important resource. A method for regularly monitoring your physical assets is asset tracking. Either the barcodes on your assets are scanned, or tags like BLE, GPS, RFID, and LoRa are transmitted. Asset tracking systems can be used to track people in addition to assets. Assets can also be tracked from anywhere in the world using specific devices that combine a GPS system with satellite phone or mobile phone technology. The complexity of PS asset trackers sets them apart from equivalent GPS tracking devices. While the former relies on an internal battery, the latter is linked to the vehicle's battery.
