punched card
C1Technical/Historical
Definition
Meaning
A stiff piece of paper in which holes are punched in specific positions to represent data, historically used to input information into early computers and data processing systems.
The term can metaphorically refer to outdated, rigid, or batch-processing methods of data handling, or to a symbol of early computing technology. It may also refer to a physical card used in voting systems (e.g., "hanging chad") or in industrial machine control (e.g., Jacquard loom).
Linguistics
Semantic Notes
The term is now primarily historical. In contemporary contexts, it is used to discuss the history of computing, to metaphorically criticize inflexible systems, or in specific technical fields like legacy industrial automation. The related term "punch card" is also common.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque "пробитая карта". The standard historical term is "перфокарта" (perfokarta). "Пunch card" is also "перфокарта". The action is "перфорировать" or "пробивать".
Common Mistakes
- Using "punched card" to refer to modern credit cards with chips. Confusing it with "index card" or "flash card". Using it as a verb ("I punched-carded the data" is incorrect).

Frequently Asked Questions
Yes, they are synonyms. 'Punch card' can refer to the blank card or the punched card, while 'punched card' specifically denotes the card after holes have been punched into it. In practice, they are often used interchangeably.
Rarely, and only in very specific legacy systems, industrial machinery (like some textile looms), or for educational/historical purposes. They are obsolete in mainstream computing.
This was a literal warning printed on IBM punched cards to prevent physical damage that would make them unreadable by the machines. It has since become a cultural catchphrase representing dehumanizing or rigid bureaucratic instructions.
Punched cards were largely superseded by magnetic storage media such as magnetic tape and later, disk drives, which offered higher speed, greater density, and reusability.
