1. A method for controlling access to a hygienically secured area, the method comprising:
identifying a probe from a mobile device;
determining a signal strength for the probe from the mobile device;
in response to the determined signal strength being below a threshold signal strength, dismissing the probe;
in response to the determined signal strength being a above the threshold signal strength, determining an identifier for the mobile device based on the probe;
receiving sensor data from a flow sensor associated with hand hygiene;
determining whether a hand hygiene threshold is met based on the sensor data;
identifying a first timestamp for the probe;
identifying a second timestamp for the sensor data associated with hand hygiene;
matching the sensor data associated with hand hygiene with the identifier for mobile device based on a comparison of the first timestamp and the second timestamp; and
generating a message to unlock a door for the hygienically secured area when the hand hygiene threshold is met.
