1.0 System Overview
The V-TAG is a RFID tag with a set of sensors for temperature, acceleration and battery
level. In contrast to other systems where each tag is polled by a central gateway, the V-
TAG tag relays messages from other V-TAG tags which aids with tag read range and
communications reliability. See Figure 1.
