Abstract
A stack of documents are transported one-at-a-time, under control of an automatic machine. A machine readable card is inserted between preselected documents in the stack. When the transport detects a passage of the card through the transport system, the machine is commanded to perform a specific function. The exemplary machine described herein is a microfilm camera, and the illustrative functions are two side copying and batch or file marking.
