1. A system for applying an antimicrobial barrier to a hand, the system comprising:
a barrier precursor material;
a reservoir for the barrier precursor material;
a housing including at least one wall defining a cavity arranged to receive the hand of a person and an opening for the hand to be positioned through when the person is next to and on an exterior of the housing;
a sensor configured to measure a length, a width, and a depth of a hand positioned adjacent the system;
a controller connected to the sensor and configured to select a size and a shape of an antimicrobial barrier required to cover the hand based on information from the sensor;
a dispenser connected to the reservoir and configured to dispense the barrier precursor material onto the hand of the person when the person is next to and on the exterior of the housing, wherein the controller is configured to control operation of the dispenser based on the size and shape of the antimicrobial barrier selected by the controller, wherein the barrier precursor material cures and adheres to the hand to form the antimicrobial barrier on the hand, wherein the antimicrobial barrier does not retain or transfer microorganisms from an object grasped by the hand, wherein the antimicrobial barrier has a first thickness in a first area of the hand and a second thickness in a second area of the hand, wherein the second thickness is larger than the first thickness to provide increased protection for the second area of the hand; and
a user interface configured to send information to the controller, wherein the information includes at least one of user credentials or payment information, and wherein the controller is configured to compare the information received from the user interface to criteria stored in the controller and restrict access to the antimicrobial barrier based on the comparison.
