Abstract

In a gasoline dispenser system, a dispenser head includes a PIN PAD for permitting a customer to privately enter their personal Identification Number into the PIN PAD at a location remote from the dispenser head, for permitting the PIN number to be transmitted to a receiver in the dispenser head, for processing via a point-of-sale authorization controller, to either authorize or deny a transaction between the customer and associated service station.

Claims

1. In a gasoline station fueling island, a gasoline dispenser head including a point-of-sale authorization (POS) terminal, the POS terminal including a message display for operational prompting, a keypad, a card reader for reading customer'"'"'s credit cards, and a printer for providing transaction receipts, wherein the improvement comprises:

portable PIN Pad means for providing in an attendant-activated mode of operation, means for a customer to privately and confidentially enter the customer'"'"'s personal identification data or number (PIN) outside the view of the attendant, the PIN being encrypted in said PIN Pad means, whereafter the customer hands the PIN Pad means to the attendant;

transmission means included in said PIN Pad means for permitting said attendant to remotely transmit the customer'"'"'s encrypted PIN number to said POS terminal;

first receiving means included in said POS terminal for receiving and decoding the encrypted PIN data transmitted from said PIN Pad means;

controller means included in said POS terminal and connected to said first receiving means, for receiving said decoded encrypted PIN data from said first receiving means, and transmitting the same to a master controller of said gasoline station;

said controller means further including second receiving means for receiving back from said master controller, a control signal indicating whether the PIN number is authorized or denied;

display means located on said POS terminal, connected to said second receiving means, for receiving said control signal therefrom and visually indicating to a "user" whether authorization is confirmed or denied; and

wherein said controller means of said POS terminal further includes for use in a customer activated mode of operation, third receiving means for receiving directly from said keypad of said POS terminal, PIN data entered into said keypad by said customer, for encrypting and transmitting the same to said master controller.

2. The improvement of claim 1, further including:

infra-red data transmission means in said portable PIN Pad for transmitting said PIN data to said POS terminal in the form of infra-red signals;

said first receiving means further including infra-red light detecting means, for converting the infra-red PIN signals to electrical signals, and means for decoding said electrical signals.

3. The improvement of claim 1, wherein said first receiving means includes an FM decoder.

4. The improvement of claim 1, wherein said first receiving means further includes means for receiving and decoding both said PIN data and credit card data from said card reader.

5. The improvement of claim 4, wherein said POS controller means further includes means for transmitting said credit card data to said master controller.
