A digit included with-in a symbol whose value is based mathematically on other characters included in the symbol. It is used to perform a check to ensure the accuracy of the read.
Suffix required (by some countries) to be added to a 10-digit HS commodity code, when filling out import documents.
A character included in a bar code for the purpose of performing a mathematical check on the value of the decoded bar code to ensure its accuracy.
check digits are used in credit cards numbers, bar codes, etc. A check digit is a digit added to a number (either at the end or the beginning) that validates the authenticity of the number. A simple algorithm is applied to the other digits of the number which yields the check digit. By running the algorithm, and comparing the check digit you get with the check digit encoded with it, you can verify that you have correctly read all of the digits and that they make a valid combination. Here is the check digit scheme for Visa/Mastercard/Amex/Discover. Here is the check digit scheme for UPC/EAN.
A check digit serves the same purpose as a check character, but it may assume numeric values only.
a character included within a symbol whose value is used for performing a mathematical check to ensure the accuracy of the code
a digit appended to the end of your Customer Reference Number to validate the accuracy of data entry by applying a mathematical formula to
a digit attached to the end of a string of digits
an important tool to help catch transcription errors
a number appended to numeric identifiers to prevent most common keying transposition errors
a single digit placed at the end of numerical computer data
A numeric character encoded in the U.P.C. symbol following the item ID. The check character is computed from the other characters of the U.P.C. and serves to check the accuracy of the code during the scanning process.
Number(s) or character(s) that is appended to or inserted into a primary key value, to confirm the accuracy of the primary key value. 13.10
A digit included within a symbol whose value is based mathematically on other characters included in the symbol. Used within bar codes it performs a mathematical check verifying the accuracy of the code.
A digit, often the final digit of a number and usually calculated by applying an algorithm to all or some of the digits in the number, which may be used to test validity of the non-check-digit number. For example, routing/transit numbers have nine digits, eight of which provided FI identification information and the ninth is the check digit.
A numeric value, which has been calculated mathematically, is added to data to ensure that original data have not been altered or that an incorrect, but valid match has occurred. This control is effective in detecting transposition and transcription errors. Check digit verification (self-checking digit) A programmed edit or routine that detects transposition and transcription errors by calculating and checking the check digit
A digit calculated from the other digits of an Element String, used to check that the data has been correctly composed
A character included within a symbol which used to perform a mathematical check to ensure the accuracy of the scanned data.
A one-character code appended to the end of a data element number which is used by the system to verify the accuracy of the element number. This code is derivable from the element number. Check digit may also be applied to funding source, but at the current time, this feature is not being used (all funding check digits are assigned a zero value).
Same as a check character, but assumes numeric values only.
A number placed after a string of numbers that is used to check that the main numbers have been input correctly into the computer.
A character included (usually at the end) of a bar code which verifies, mathematically, the correct scan of the bar code. (Also called Check character, Checksum, Mod10 Checkdigit, or Modulus 10 Checkdigit).
A digit is included within a symbol whose value is used to perform a mathematical check that ensures the accuracy of the read. It is placed immediately after the barcode data.
A calculation used for the last digit of the account number to ensure that duplicate accounts do not exist. The check digit also provides a security system for the account number. Since the entire account number is used in the calculation, the check digit helps prevent fraud.
A check digit is a form of redundancy check used for error detection, the decimal equivalent of a binary checksum. It consists of a single digit computed from the other digits in the message.
