Why RFID, GPS, and IoT Each Solve Different Asset Tracking Problems

Knowing that an asset exists is simple, but determining its location, movement, and condition is often much harder. RFID uses radio waves to identify tagged items through compatible readers and suits inventory checks, though it does not provide continuous location tracking on its own. GPS is better suited to vehicles and mobile equipment moving across roads or remote sites, but it can struggle indoors and raises power and connectivity considerations. IoT sensors add context such as temperature and humidity, which helps confirm whether conditions like cold-chain requirements are being met. The article argues that the main engineering challenge is integrating these technologies into a single system so users do not have to compare separate dashboards.
