Abstract: A secure and efficient system and method that allows restaurant patrons to combine, split and/or pay for one or more components of an outstanding bill via a mobile computing device. In the most ideal embodiment, the restaurant has an existing order management/Point of Sale (POS) system installed on a computer network with wireless (Wi-Fi or Bluetooth) capabilities. When patrons have finished eating and are ready to pay for their bill, all outstanding check details are downloaded from a POS database to a mobile computing device over the wireless network. Each patron reviews the check details (listed in an orderly fashion on the screen of the mobile device) to determine how much they each want to pay. Patrons can pay for all or specific parts of the entire bill as well as all or specific parts of each item that was ordered.
