A fuel dispensing system having seven separate fuel pumps for dispensing fuel, a pump activation system permitting each of eight hundred authorized users to individually activate a fuel pump the is authorized to use and having a keyboard for user selection of an inactive pump and user entry of an assigned unique nine-digit identification number, digit by digit in descending order sequence, for activating the selected pump. Entry controls and a RAM are provided for validating the identification number and for activating the selected pump if the identification number is correct and an authorized pump is selected and for totalizing the amount of fuel dispensed by each user, and a main console is provided for selectively setting and reading each user\s identification number and pump authorization code and for selectively reading the total amount of fuel dispensed by each user and resetting the total to zero.
