1. A hand sanitization system comprising:
at least one sanitization unit comprising:
a 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 predetermined range of the proximity sensor;
a dispenser attached to the at least one sanitization unit;
an alarm being operative to provide an indication that the dispenser did not dispense antiseptic solution within a particular predetermined period of time after the proximity detector determined that the person was within the predetermined range of the proximity sensor;
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;
the at least one tag comprising a tag radio frequency module operative to communicate with the at least one sanitization unit and the 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 did not dispense antiseptic solution from the dispenser within the particular predetermined period of time after the proximity detector determined that the person was within the 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 predetermined range.
