ORDERING SYSTEM

摘要

A product ordering system comprising a central unit and at least one user terminal is provided. Each user terminal comprises first processing means for processing data, reader means for reading product data from a portable data carrier, user interface means for enabling a user to input order instructions to the terminal, transmitter and receiver means for transmitting an order signal representing the input order instructions and the read product data, together with an identification code identifying the particular user terminal, and for receiving response signals sent from the central unit to that user terminal, and a power supply for supplying power to the terminal. The central unit comprises processing means for processing data and having a memory for receiving and storing data, and transmitting and receiving means for receiving order signals from user terminals and for transmitting response signals to user terminals. The invention provides a much more convenient ordering system. It allows a user to receive immediate confirmation that an order has been received. It also avoids the need for the user to have details about the product which he/she is ordering.
