A system and method of encouraging compliance of hand hygiene in an environment where users move from zone to zone and are required to perform hand hygiene between the zones. Users carry a wearable zone sensor which detects zones, detects hand hygiene actions, logs time of changing zones, and hand hygiene actions. The wearable sensor can be integral with a wearable hand hygiene product dispenser and/or can operate in cooperation with a fixed dispenser configured to transmit hand hygiene actions to the wearable zone sensor. The wearable zone sensors are configured to be useable anonymously or to be associated with a user identifier, and to interface with a central computer via a docking station or communication interface to transfer data for later analysis.
