In-dispenser-card-reader control system

摘要

The present invention relates to a fuel dispenser control system which controls the fuel dispensing process and accepts payment for the fuel dispensed through a card reader. The dispenser controller has a microprocessor with read-only-memory (ROM) and read-and-write-memory (RAM). A series of commands are stored in the ROM for controlling the dispensing process and accepting payment for the fuel dispensed. Configuration circuits' translate the communication language of the dispenser controller into a communication protocol readable by the dispensers such that the dispensing process of various dispenser brands can be controlled and payment for the fuel accepted. Response data from the dispenser is stored in the RAM, and then passed up a register system.
