Point of Sale System with Deferred Payment

The flow charts in the drawing shows the operation of a point of sale terminal for a deferred payment operation in an application such as a restaurant. In this application, the operator of the terminal usually is a server.

A circle in the flow chart represents an operator guidance step, in which the point of sale terminal signals the operator through a system of indicator lights or other visual display means. Rectangles identify operator steps of keying functions or data, or identifying processor responses to these inputs. Diamonds represent logical operations by the processor. The processor functions are divided between a limited capability processor within the point of sale terminal and a remote processor that handles several terminals.

In step 3 the operator guidance message, Transaction Type, tells the operator that the system is ready to begin a new transaction when the operator keys "Service" or any "Revenue Collection" type transaction of step 4. A revenue collection transaction is a customer payment that terminates the customer's account such as cash or charge, and a service transaction enters an item into the account when payment will be deferred. In blocks 5, 6, 7 and 8 the server enters a personal identification number and a previously assigned guest check number.

In an initial operation to set up an account, the operator keys "Enter" without a guest check number and in subsequent operations on an open account, the operator enters the number from the printed guest check. This number is assigned by the system and includes the operator ID, a guest check number and a module check digit.

Block 9 shows a test that takes place in the terminal to distinguish between a new account entry and a subsequent entry. Blocks 10 and 11 show the operations for setting up a new account when the operator has not entered a guest check number. The terminal transmits a request to the processor and the processor assigns a guest check number and a check digit, and it controls a printer to print these items on a guest check. The operation then proceeds to guidance step 12, in which the operator is instructed to enter an item that is to become part of the guest check.

Blocks 13 and 14 show the operation when an entry is made on an...
