Tag life cycle (simplified). The tag firmware is organized around this (simplified) state machine. The key life phases are Erased (no data or configuration are stored), Active (tag is configured for data collection), and Completed (data collection has ceased). State transitions initiated by the host are illustrated with solid arrows. Tag-initiated state transitions are illustrated with dashed arrows
