ABSTRACT:
A fuel dispenser-credit card reader control system for controlling the fuel dispensing process and accepting payment for the fuel dispensed through a card reader is disclosed. The dispenser controller has a microprocessor with read-only-memory for storing operating routines and command code and read-and-write-memory for storing responses. 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. A feature of the disclosure is that the controller includes a command for transmitting an encrypted PIN number data block from the card reader to a site controller without analyzing the data, manipulating the data, or permanently storing the data.
