Abstract: A multimedia point-of-sale (MMPOS) network system has a server, a plurality of client computing devices used by a plurality of customers, one or more MMPOS terminals deployed in one or more establishments, and a network. The system stores customers' profiles in a database. When a customer visits an establishment, the system identifies the customer, accesses the customer's profile, retrieves the allergy information and food preferences of the customer, displays a menu on a MMPOS terminal used by the customer, and highlights one or more first menu items on the menu based on the retrieved food preferences, and/or presents an alert on one or more second menu items on the menu based on the retrieved allergy information.
