Abstract: Methods and systems for tracking a sale of an alcoholic beverage to an individual at a venue includes personalized information, such as height, weight, age, prescription medicines, etc., tied to a local or remote identifier of the individual. During use, the individual presents the identifier to an operator at the venue so that the personalized information can be accessed. In one instance, this includes the further accessing of a database of records. Once obtained, and in comparison to specifics about the type, volume, alcohol content, etc. of the alcoholic beverage, it is determined whether consumption of the alcoholic beverage will cause the individual to become intoxicated, especially according to a standard measurement, such as a blood alcohol content of the individual based on a formula. The denying or consummating of the sale occurs thereafter as does the updating of the personalized information and/or database of records.
