Recordak

In 1927, the Recordak, the first check photographing device began commercial manufacture by the Recordak Corporation, a newly-formed subsidiary of the Eastman Kodak Co., Rochester, NY. Designed to simplify bank records, the machine photographed checks onto 16mm film. It was invented by George Lewis McCarthy, who called it a Checkograph and was issued his patent on 25 Feb 1930 (No. 1,748,489). By 1935, it was also used in libraries for the purpose of making microfilm records, beginning with the New York Public Library photographing the New York Times of the WWI period. Microfilming itself began in the early 1800s. Microphotography for military purposes was first used in the Franco-Prussian war (1870 ).
