In the case of a pizza home delivery system, customer addresses and mapping information may be auomatically retrieved and displayed based on customer telephone number, and order data including an assigned order number may be imprinted on a label to be attached to each pizza container. Preferably, the system produces the order number in the form of a bar code on an adhesively backed label. Each driver may check out order for delivery by inserting his coded identification key at a bar code reader station and having the bar code labels scanned into the system, so that each order is assigned to a particular driver in a reliable and accurate manner. A voice synthesizer unit at the station can then remind the driver that the order includes beverages or more than one pizza container, and can advise the driver when the sum of the cash payments he has received for his deliveries exceeds a certain amount, making it advisable to deposit some of the accumulated cash before the next delivery. The system is modular and readily expanded to a multi-store system with a centralized telephone order entry station.

There is disclosed an apparatus and technique for recovering frequency-shift-keyed (FSK) data from a conventional FM detector while allowing the system to operate over wide temperature ranges without FM detector temperature compensation. The FSK input signal is coupled through a bandpass filter and differentiated to provide positive and negative voltage spikes. The voltage spikes are compared with positive and negative reference levels to produce set and reset inputs to a set/reset flip-flop. The output from the flip-flop is a reconstruction of the FSK data which is not affected by temperature-related DC offsets and detector drift.
