wedes feed paper bills to pump to receive gas — A master automat for controlling several different gasoline pumps at once allows a driver to fill his own tank after hours by putting paper money in the slot.... A photoelectric scanner rejects false notes or those of wrong denomination.... Coin-operated gas automats have been used in Sweden for some time but have been found less practical, especially for long-distance drivers, because of the number of coins needed to fill a nearly empty tank. — Science News Letter, September 4, 1965
