Unattended automated system for selling and dispensing fluids, with change-dispensing capability

摘要

A system for selling and dispensing of fluids, with change- making capability permits and the unattended sale and dispensing of motor fuels. The system may be incorporated either directly into a motor fuel pump or it may be incorporated into a module that may be installed either in a motor fuel pump or on a fueling island in association with the motor fuel pump. A cash acceptor is provided that accepts either currency or coin as a payment for a motor fuel purchase and the system further includes a change dispenser for disbursing change to a purchaser. The change dispenser includes two different change payout mechanisms that give cash back to a purchaser as change for a motor fuel purchaser. The change is dispensed in currency, or coin, or a combination of both. A controller is provided that links the cash acceptor, fuel pump and change dispenser together so that the value of cash deposited with the system is identified and the motor fuel pump is enabled.
