Introduction
SGZ308, a wearable presence tag, acts as an IAS device for minor children/aged-care use. It is an
ideal product to detect one’s presence within/ out of the network coverage for safety purpose.
SGZ308 periodically sends presence/absence report to keep a close watch on those who wear it.
