1. A hand sanitization system comprising:
at least one sanitization unit comprising:
a proximity detector operatively connected to a housing, the proximity detector operative to determine proximity of a person with respect to the at least one sanitization unit;
a proximity sensor action counter operatively connected to the proximity detector, the proximity sensor action counter for counting each proximity indication from the proximity detector indicating when the person is within a particular predetermined range;
a sanitizer action counter operatively connected to a dispenser attached to the at least one sanitization unit, the sanitizer action counter for counting each time the particular dispenser is activated;
an alarm operatively connected to the housing, the alarm operative to provide an indication that the particular dispenser was not activated within a particular predetermined period of time after the person entered the particular predetermined range of the at least one sanitization unit;
an alarm counter operatively connected to the alarm, the alarm counter for counting each time the alarm is activated; and
a sanitization unit processor operatively connected to memory and a sanitization radio frequency module for communicating with at least one tag and a central computing system; and
the central computing system in communication with the at least one sanitization unit and the at least one tag and comprising at least one centralized processor for receiving an alert notification in response to receiving: a) an indication from the at least one sanitization unit that the dispenser was not activated within the particular predetermined period of time after the person entered the particular predetermined range of the at least one sanitization unit; and b) an indication from the at least one tag that the at least one tag has moved beyond a predetermined distance from the particular predetermined range.
