Check photographyIn 1930, the first bank check photographing device patent was issued in the U.S. to its inventor, George Lewis McCarthy, who called it a Checkograph (No. 1,748,489). In 1927, the Eastman Kodak Co., Rochester, NY had commenced its commercial manufacture as the Recordak. The machine photographed checks onto 16mm motion picture film using a conveyor belt before they were returned to customers. It was subsequently developed to use 35mm film and also used in libraries for the purpose of making microfilm records, beginning with the New York Public Library (1935) photographing the New York Times of the WWI period. This solved difficulties in archive storage and use of newspapers, and the rapid deterioration of the newsprint original. |
