Check digit: A form of redundancy check used for error detection on identification numbers (e.g., bank account numbers, credit card numbers). It is a digit added to a string of numbers and is calculated from the other digits in the string. The presence of this additional digit helps in identifying incorrect input of the number sequence, thereby aiding in the prevention of data entry errors and enhancing the integrity of data.
