A retail transaction system provides enhanced customer convenience and increased transaction security by sending transaction information to a cellular network provider via a customer's digital cellular phone. For example, a fuel dispenser is equipped with a communications link allowing direct communications to a customer's cellular phone. When a customer desires to conduct a transaction using the fuel dispenser, the fuel dispenser transmits select information to the customer's cellular telephone using this communications link. A telephone number is included in the select information. When the customer presses send, or otherwise causes their telephone to dial the number transferred from the fuel dispenser, the select information along with any additional customer information is sent to the cellular network. This information is used by the network to authorize a purchase transaction for the customer, such authorization information returned to the fueling station at which the fuel dispenser is located via a cellular link. For enhanced security, the customer may be required to input their PIN in order to complete the transaction. Notably, the PIN and the remainder of the transaction information sent from the customer phone to the cellular network is intrinsically secure due to the digital encryption employed by the digital cellular protocol. Optionally, the system may be configured to cause the customer's cellular phone to automatically dial the number transferred by the fuel dispenser. This capability may be enabled at the customer's option. The system may be extended to other retail systems including in-store point-of-sale systems (POS).

Two or more hoses can be simultaneously connected to different equipment in need of refueling. A valved fuel tank inlet line enables fuel to flow from the manifold to a fuel tank on the dock. When needed, fuel from the tank can then be pumped to the manifold through a fuel tank outlet line,.which can be connected to the same inlet on the manifold that is used to receive fuel from the tanker trick.

A system and method to adapt a fuel dispenser and related facilities to accept bar coded cards in addition to or instead of magnetic strip cards. A standard bar code reader is used in conjunction with a magnetic strip card reader. The bar code reader includes a light detector and a light source. The light detector and light source are secured so that they may visually access a card in the magnetic strip card reader. This allows the light detector to access bar coded data that is printed on a bar coded card. Furthermore, the addition of the bar code reader does not prevent the magnetic strip card reader from also reading a magnetic strip if it is present on the card. When a bar coded card is slid into the magnetic strip card reader, the bar code reader interprets the signals generated thereby and "decodes" the signals into corresponding numbers. These numbers are then sent over a data bus to a controller, where they are interpreted. Once interpreted, the numbers can be used similarly to numbers conventionally produced by a magnetic strip card, or can be used separately to provide additional services and / or advantages, such as updating a frequent purchase account.
