Tracking ULDs

摘要

Airlines have been investing in technologies to keep track of their containers, pallets and unit load devices (ULDs) to improve not only their own operations, but also the quality of information they can give the customer about their shipment. Two technologies seeing investment are radio frequency identification (RFID) and Bluetooth. While the former is regularly encountered by people in shops as security tags, and the latter at home with consumer electronics, for aviation they are a relatively new development.
