Abstract

A method and apparatus for detecting typing errors of critical fixed series of characters (digits) by using at least one redundant parity digit. The invention detects the most common typing errors that involve both permutations and incorrect striking of adjacent characters during data entry via a keyboard of an electronic apparatus. The method provides warning to the data input operator when incorrect data entry occurs and optionally automatically suspends entry thereof.
