Patent attributes
A method includes: in response to detection of a patron, capturing N sets of identification data for the patron using N passive patron identification systems, respectively, wherein N is an integer greater than one; calculating N partial confidence values based on N comparisons of the N sets of identification data with N sets of stored identification data, respectively, associated with a unique patron identifier; and, based on the N partial confidence values, calculating an overall confidence value indicating a level of confidence that the patron is associated with the unique patron identifier. The method further includes: based on the unique patron identifier, retrieving stored ordering data that is associated with the unique patron identifier; setting ordering information to be output to the patron based on the overall confidence value and the stored ordering data; and outputting the ordering information to the patron using an ordering terminal.
