The standard measure of speed is cards per minute, abbreviated CPM: The number of cards which can be read or punched in one minute. Card reader models vary from 150 to around 2,000 CPM. [3] [4] At 1200 CPM, i.e. 20 cards per second, this translates to 1,600 characters per second (CPS), assuming all 80 columns of each card encode information.
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 ...
