US Patent 11667510 Beer tap monitoring system

A monitoring system of a beer tap station is disclosed. The monitoring system can determine when a beer is being dispensed from the beer tap station and also which beer tap of the beer tap station is being pulled (i.e., which beer is being dispensed). The monitoring system also receives customer transaction data from a point of sale system and correlates data between the monitoring system and the point-of-sale system to detect errors and unauthorized serving of beer.
