Check digit
consists of one or more characters for detecting substitution errors, e.g. when reading barcodes. The P. is created using various calculation methods. The most common is the calculation according to modulo 10/weighting 3 (modulo), which is used for EAN codes and codes of the 2-out-of-5 family.

- Check DigitA check digit, also known as a check digit, is an additional digit or a small set of digits that is added to a sequence of numbers to improve error detection during manual or automated data capture. This check digit is calculated to ensure that the entered or scanned sequence of numbers is correct and that there are no transmission errors. Importance of the check digit The check digit plays a crucial role in ensuring data integrity and error detection in identification systems. By using a check digit, errors such as typing errors, transposition errors or incorrect scans can be quickly detected and corrected. This is particularly important in sectors such as retail, logistics, healthcare and financial services where data accuracy is critical. Using Check Digits with GS1 Europe GS1 Europe provides standards and guidelines for the implementation of identification systems, including the use of Check Digits. By integrating GS1 identification systems, companies can ensure that their product and transaction data is accurate and reliable. Using Check Digits in accordance with GS1 standards helps to improve data processing efficiency and minimize errors. Advantages of using Check Digits The use of check digits offers various advantages:
- Error detection: the check digit enables quick detection of transmission errors and helps to improve data quality.
- Security: By using Check Digits, potential data manipulation or attempted fraud can be detected and prevented at an early stage.
- Efficiency: Implementing Check Digits in accordance with GS1 standards helps to increase the efficiency of data processing and transmission.
