Abstract: A method and apparatus for detecting a multiple-feed situation with regard to documents having encoding arranged thereon in a predetermined manner and with the documents being moved along a transport path. In a preferred embodiment of the invention, the documents are encoded with magnetic ink. A sensing member is positioned along the transport path in operative relationship with the encoding on the documents for generating a first signal in response to a character of the encoding being in moving relationship with the sensing means. A first circuit is used for receiving the first signal and for generating a first time frame. A second circuit is used for generating a second time frame beginning upon the expiration of the first time frame; and a third circuit is used for generating an output signal indicative of a multiple-feed situation when a subsequent signal from the sensing means occurs during the second time frame.
