In the 1970s, computer-aided manufacturing equipment often used paper tape. A paper tape reader was smaller and less expensive than Hollerith card or magnetic tape readers, and the medium was reasonably reliable in a manufacturing environment. Paper tape was an important storage medium for computer-controlled wire-wrap machines, for example.

Needless to say, the demise of paper tapes as a core element in the distribution and management of their cryptographic keys will see the NSA adopting digital methods. When buying paper for your home or office, you need to consider size (A3, A4, etc.), paper weight (gsm which stands for 'grams per square metre'), colour and your printer (inkjet, laser).

At the University of Wisconsin – Madison, the exterior windows of the Engineering Research Building [80] were modeled after a punched card layout, during its construction in 1966.

Hollerith's original system used an ad hoc coding system for each application, with groups of holes assigned specific meanings, e.g. sex or marital status. His tabulating machine had up to 40 counters, each with a dial divided into 100 divisions, with two indicator hands; one which stepped one unit with each counting pulse, the other which advanced one unit every time the other dial made a complete revolution. This arrangement allowed a count up to 9,999. During a given tabulating run counters were assigned specific holes or, using relay logic, combination of holes. [40] a b Truesdell, Leon E. (1965). The Development of Punch Card Tabulation in the Bureau of the Census 1890–1940. US GPO. p.43. Includes extensive, detailed, description of Hollerith's first machines and their use for the 1890 census. Paper tapes constructed from punched cards were widely used throughout the 19th century for controlling looms. Perforated paper tapes were first used by Basile Bouchon in 1725 to control looms. However, the paper tapes were expensive to create, fragile, and difficult to repair. By 1801, Joseph Marie Jacquard had developed machines to create paper tapes by tying punched cards in a sequence for Jacquard looms. The resulting paper tape, also called a "chain of cards", was stronger and simpler both to create and to repair. Suitable for high volume printing, faxing and copying, the 500 sheets of A4 business paper give exceptional reliability when used in high-speed laser and colour inkjet printers as well as copier machines.
