Question

Quizplus · Accepted Answer

Check digits are added to data codes in order to detect transcription and transposition errors, meaning errors that occur during data entry. This improves accuracy and ensures that the correct information is being used. Check digits can be placed anywhere within a data code, not just at the end, and can vary in length depending on the system being used. However, the use of check digits can slightly impact processing efficiency because it requires an additional step to verify the code. Nonetheless, the benefits of improved accuracy outweigh this minor drawback.
