Abstract
A hand hygiene monitoring system is provided. The system includes a wearable tag device coupled to a user, and a reader device communicably coupled to the wearable tag device. The reader device is configured to detect a presence of the wearable tag device by receiving a first frequency message comprising a user identifier from the wearable tag device. The reader device is further configured to transmit a second frequency message to the wearable tag device requesting event log data. The second frequency has a higher frequency than the first frequency. The reader device is further configured to receive an event log data message from the wearable tag device at the second frequency, and to determine whether the wearable tag device has logged a wash station encounter within a configurable time period based on the event log data message.
