The system may include one or more micro-zone (mZone) transmitters configured to be deployed at designated locations where hand hygiene compliance is desired. A given mZone transmitter may transmit an mZone signal including data pertaining to its type and identity, from which its purpose and location may be derived. A monitored individual may host a beacon tag configured to receive the mZone signal and pull mZone type and identification data therefrom, relaying that data in its own beacon signal, along with current hand hygiene compliance or non-compliance status data. The beacon tag may be programmed with one or more hand hygiene compliance modes selectable based on the desired monitoring context. The beacon signal may be received by any gateway or reader device within transmission range. In this manner, compliant and non-compliant events may be tracked. ## Claims ### Claim 1 A wireless hand hygiene compliance tracking system comprising: a micro-zone transmitter device configured to transmit a first signal including data pertaining to a unique identifier associated with the micro-zone transmitter device and a type of the micro-zone transmitter device, wherein: the type of the micro-zone transmitter device is indicative of whether the micro-zone transmitter device is configured to be deployed at a patient zone, an unsanitary zone, a hand washing station zone, or a hand sanitizing station zone;
