If a barcode scanner reads a code but displays the wrong product, where may the problem be?

Answer and explanation

Correct answer: An incorrect mapping in the product database

Reading the barcode successfully shows that the scanner is capturing and transmitting the code. If the displayed product is wrong, the system may be matching that code with an incorrect record, such as a mistaken database entry or product-code mapping. Option A is correct. Monitor power, the scanner’s colour, and the computer fan do not determine which product record is selected.
