Abstract: A system and method of dispensing a beverage to a customer is described, wherein the system includes a first scanner and a second scanner for identifying a unique identifier, each operatively connected to a computer system. Upon purchasing a beverage under an applicable contractual scheme, management of a beverage outlet issues a unique identifier to the customer and registers the unique identifier in the computer system. When the customer wishes to take a fill or a refill of the beverage, she must pass the unique identifier across a second scanner that will record the incremental use of the identifier. The computer system assesses whether or not a rule of use has been violated, and will only permit the dispenser to dispense where the rule has not been violated.
