What is meant by Check digit calculation?
The term "automatic check digit calculation" refers to the automated process of computing check digits used to verify the correctness and integrity of data sets, such as barcodes, account numbers, or ISBNs. A check digit is calculated using a specified algorithm and appended to the end of a data set to detect and prevent input or transmission errors.
Typical software functions in the area of "automatic check digit calculation":
- Algorithm Selection: Ability to select the appropriate algorithm for check digit calculation, such as Modulo-10, Luhn algorithm, or Verhoeff algorithm.
- Real-time Calculation: Immediate calculation of the check digit during data entry or creation.
- Validation: Automatic verification of the validity of the entered data by comparing it with the calculated check digit.
- Error Indication: Highlighting data sets with invalid check digits for immediate error correction.
- Integration: Seamless integration of check digit calculation into existing data management systems and applications.
- Reporting: Generating reports on check digit calculation and validation for audit and compliance purposes.
