punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and storage. many early digital computers used punched cards, often prepared using keypunch machines, as the primary medium for input of both computer programs and data.
