Abstract

A system (500) for identifying an unidentified customer (510) includes a database (42) that contains utterance data (162) corresponding to a known customer. A processing system (502) coupled to the database (42) receives utterance information corresponding to the unidentified customer (510) at the point of sale and compares the utterance information with the utterance data (162) to identify the unidentified customer (510) as the known customer. In response, the processing system (502) may automatically retrieve stored information (104, 132, 162) corresponding to the known customer.
