College Mathematics Journal, v22 n3 p194-202 May 1991
Discussed are the mathematical methods for detecting a variety of common error patterns within the bar-coded identification numbers utilized in conjunction with scanning devices. Schemes for the use of check digits are examined that ensure conditions for detecting errors of specific types, including single digit error, transposition error, twin error, phonetic error, and jump twin error.
