Which technology helps reduce errors in inventory and billing by tagging items with codes?

• A. Bar coding
• B. Attitude
• C. Graphic sheet
• D. Nonjudgemental

Answer: (A)

Using coded labels that can be read by a scanner is the method that reduces mistakes in tracking inventory and handling billing. Bar coding puts a unique, machine-readable code on each item. When that code is scanned, the system instantly pulls up the correct item data—like its name, price, and stock level—so data isn’t typed in by hand. This eliminates many manual-entry errors, speeds up transactions, and helps keep inventory records accurate in real time.

The other terms don’t serve this purpose. Attitude is a personal quality, not a data-capture technology. A graphic sheet is a printed visual document, not a tag that can be scanned to retrieve item information. Nonjudgemental is another trait, unrelated to tagging or data capture. Bar coding is the best fit for tagging items with codes and reducing errors.
