An IBM 80-column punched card of the type most widely used in the 20th century IBM 1442 card reader/punch for 80 column cards. A computer punched card reader or just computer card reader is a computer input device used to read computer programs in either source or executable form and data from punched cards.
The IBM 1402 was a high-speed card reader/punch introduced on October 5, 1959 as a peripheral input/output device for the IBM 1401 computer. It was later used with other computers of the IBM 1400 series and IBM 7000 series product lines.
A card reader is a data input device that reads data from a card-shaped storage medium and provides the data to a computer. Card readers can acquire data from a card via a number of methods, including: optical scanning of printed text or barcodes or holes on punched cards, electrical signals from connections made or interrupted by a card's punched holes or embedded circuitry, or electronic ...
PAX Technology S90 credit card terminal with a Visa card inserted.. A payment terminal, also known as a point of sale (POS) terminal, credit card machine, card reader, PIN pad, EFTPOS terminal (or by the older term as PDQ terminal which stands for "Process Data Quickly" [1]), is a device which interfaces with payment cards to make electronic funds transfers.
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
Most card readers also offer write capability, and together with the card, this can function as a pen drive. Some printers and Smartphones have a built-in card reader, as do many laptops and the majority of Tablet computers. A multi card reader is used for communication with more than one type of flash memory card. Multi card readers do not ...
When a card is presented to the reader, the reader's electrical field excites a coil in the card. The coil charges a capacitor and in turn powers an integrated circuit. The integrated circuit outputs the card number to the coil which transmits it to the reader. The transmission of the card number happens in the clear—it is not encrypted.
An "informative" (i.e. non-mandatory) annex [7] describes how an ID-000 sized card may be included in an ID-1 size card for processing (e.g. in an ID-1 reader), but with "relief areas around the perimeter of the ID-000 size card to allow it to be removed from the ID-1 size card without punching tools". An ID-1 size card containing an ID-000 ...
