From The Jargon File (version 4.4.7, 29 Dec 2003) [jargon]:
punched card
[techspeak] (alt.: punch card) The signature medium of computing's {Stone
Age}, now obsolescent. The punched card actually predated computers
considerably, originating in 1801 as a control device for mechanical looms.
The version patented by Hollerith and used with mechanical tabulating
machines in the 1890 U.S. Census was a piece of cardboard about 90 mm by
215 mm. There is a widespread myth that it was designed to fit in the
currency trays used for that era's larger dollar bills, but recent
investigations have falsified this.
IBM (which originated as a tabulating-machine manufacturer) married the
punched card to computers, encoding binary information as patterns of small
rectangular holes; one character per column, 80 columns per card. Other
coding schemes, sizes of card, and hole shapes were tried at various times.
The 80-column width of most character terminals is a legacy of the IBM
punched card; so is the size of the quick-reference cards distributed with
many varieties of computers even today. See {chad}, {chad box},
{eighty-column mind}, {green card}, {dusty deck}, {code grinder}.
