Aperture card scanners are machines that scan the contents of aperture cards and produce a digital file. An aperture card is a punched card that has a microfilm chip affixed in a cut-out window. Usually 35mm tall, the microfilm chip contains a reduced image of a reference document. An example might be an engineering drawing.
Although still used in many archiving projects, a greater number or organizations prefer to digitize aperture cards to provide a duplicate format or an entire replacement.
