Retail Gasoline Service Stations

Credit/debit card authorization systems for retail gasoline service stations are illustrated in Exhibit 111-12.

Retail gas stations and closely allied convenience stores are a rapidly emerging market for offering credit card authorization services. Although bank debit card transaction experiments are underway, primary action is with oil and bank credit card transactions.

Completely automated card transaction systems for gas stations include:

Card authorization terminals.

Electronically metered gas pumps.

A station microcomputer system with a data base.

A local area switch.
Credit card authorization proceeds as follows:

The consumer activates a selected gas pump.

The consumer enters credit card information through the card strip reader at the authorization terminal.
