The present invention relates to a method and apparatus for authorizing the activation of a energy or fuel dispenser as well as paying for the dispensed fuel. The method and apparatus of the current invention allow a energy or fuel station customer to dial a central dispenser activation and payment center from a telephone, such as a cellular telephone, so that dispenser authorization and payment may be accomplished conveniently and efficiently. The central dispenser activation and payment center is located either local to or remotely from the energy or fuel station.

Additionally, a cellular telephone activated dispenser activation unit could be positioned at a particular energy or fuel station, or even at a particular energy dispenser or fuel pump.

2. Description of the related art.

Current energy or fuel dispenser technology includes several alternative methods for dispenser authorization and payment tender."Prepay"pumps utilize a system of payment tender and pump authorization which requires the station customer to tender payment to the station operator in cash or

other acceptable form prior to the attendant authorizing the dispenser's use. Such a"prepay"system of dispenser authorization and payment tender is inconvenient and inefficient for several reasons. Typically, the self service station customers fill or load their vehicles and, thus cannot predict the exact charge for their energy or fuel purchase.

With this in mind, customers of"prepay"type dispensers must overpay and return to the station attendant for change, or must experience the inconvenience of incrementally filling their vehicle in an amount less than that required to bring the vehicle's energy or fuel reservoir to full.

Some dispensers utilize attached card readers which are operative to receive information from, e. g., debit, credit and ATM cards. This information, coupled with any required personal identification number (PIN) information may then be utilized to submit required payment and to signal that the dispenser should be activated after payment verification is received. These attached card reader systems represent an improvement over a"prepay"type of dispenser authorization since interaction with the station attendant is effectively eliminated. For the same reason, they represent an improvement over post-pay systems in which a customer may fuel or load his vehicle and subsequently enter the station to present payment.

Use of such card readers involve many steps in that they require the station customer to exit his vehicle, produce the appropriate card, correctly insert the card into the card reader, and enter any necessary personal identification numbers. This additional pre-fueling or pre-energizing activity slows the fueling process and requires the fueling station customer to perform additional activities at the energy or fuel dispenser in an effort to refuel his vehicle.

In addition to the above-described methods of dispenser activation and payment for dispensed fuel, RF identification equipment has been utilized to transmit payment information to a energy or fuel dispenser. RF identification devices of this kind can transmit credit, debit or ATM card information to the dispenser, thus eliminating the need for the customer to produce the appropriate card and utilize the card reader on the dispenser. RF identification payment authorization equipment typically comes in the form of a key chain RF transmitter (i. e., a keyfob) or an RF transmitter on the vehicle. Both of these RF identification embodiments have limitations.

The key chain RF transmitter can be cumbersome and requires that the station customer remove the keys from his vehicle and pass the key chain RF transmitter past a receiving device on the energy or fuel dispenser. This method of utilizing an RF identification payment authorization device

requires that the fuel station customer perform predispensing, out of car activity. While a car mounted RF transmitter does not require such activity, its versatility is limited since it is fixed to a particular vehicle and, thus could not easily be used with other vehicles.

In addition to transmitting credit, debit or ATM information to a fuel dispenser, RF identification can be used to associate vehicles with billing records for later billing.

In these embodiments, RF identification has limited utility since it is generally usable only at one particular energy or fuel station chain.

What is needed in the art is a method and apparatus which allows for convenient payment authorization of a energy or fuel dispensing apparatus from within a vehicle, which can be utilized with a plurality of vehicles, and which allows the station customer to choose his desired method of payment.

SUMMARY OF THE INVENTION The present invention provides a method and apparatus for payment authorization and fuel dispenser or energy dispenser activation which does not require the station customer to exit his vehicle to perform payment authorization activity.

Corresponding reference characters indicate corresponding parts throughout the several views. The exemplification set out herein illustrates one preferred embodiment of the invention, in one form, and such exemplification is not to be construed as limiting the scope of the invention in any manner.

DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings and particularly to Fig. 1, telephonic dispenser activation and payment system 20 allows an energy or a fuel station customer to utilize a cellular telephone to contact 13 central dispenser activation and payment center 14. Central dispenser activation and payment center 14 is communicatively linked to dispenser control 10 via a communication line 18. In this way, central dispenser activation and payment center 14 may be operable to signal dispenser control 10 to activate a energy dispenser or fuel dispenser.

As illustrated in Fig. 2, central dispenser activation and payment center 14 may be further communicatively linked to local dispenser authorization unit 16 via communication line 22. In this embodiment of the current invention, central dispenser activation and payment center 14 does not directly signal dispenser control 10 to activate the dispenser but rather communicates authorization to activate the dispenser to a local dispenser authorization unit 16 which is further communicatively connected to dispenser control 10.

Central dispenser activation and payment center 14 may be formed from a central computer system as is known in the art.

Central dispenser activation and payment center 14 may include a plurality of modems through which cellular telephone (s) 12 may establish a telephone link 13 to central dispenser

activation and payment center 14. Additionally, central dispenser activation and payment center 14 may include live operators to field incoming authorization calls 13.

Alternatively, other equivalent communication systems such as satellite telephones and a global computer network (Internet) may also be used in replacement of the telephone network.

Local dispenser authorization unit 16 could be located within a convenience store attached to the fueling station.

Local dispenser authorization unit 16 would be operative to receive payment authorization information from central dispenser activation and payment center 14 and would be communicatively connected to the appropriate dispenser controls to control the dispensers at the particular station in which it is located.

In operation, a consumer could provide payment information to be stored within central dispenser activation and payment center 14. In another embodiment, cellular telephone (s) 12 could be utilized to provide credit, debit or ATM card information to central dispenser activation and payment center 14. Central dispenser activation and payment center 14 could then authorize a energy or fuel sale based upon available funds or credit and would communicate such authorization to dispenser control 10. Since a cellular telephone would be utilized to trigger the activation of a fuel dispenser, a consumer could perform this task as he

approached the filling or energizing station. If the customer commonly utilized the same filling station, a station identification could be preprogrammed into the customer's cellular telephone to further facilitate the fueling or energy transfer process. Additionally, the costs for the fueling, energy, and other products or services (e. g., food or other products) could be charged to the customer cellular telephone service bill.

It should be understood that the teachings of the current invention are not limited to cellular telephone communications and to dispensers. The teachings of the current invention could be utilized with any mobile communication device and could be utilized to preauthorize the receipt and payment of any dispensed or distributed product or any service provided.

While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
