Quizplus · Accepted Answer

Scanners and the UPC (universal product code) have made it easier to track sales and gather data on product purchases. This technology allows for more accurate and efficient collection of sales data, which makes it easier to measure the impact of marketing campaigns. While commercial database services, the power of retailers to control sales data, and internet technology may also provide useful data, scanners and the UPC are specifically designed for tracking sales and are therefore the most relevant choice.
