Scanner technology has enabled retailers to do what with sales data?

The selection highlights how scanner technology empowers retailers to share valuable sales data with suppliers. This exchange is crucial in today's retail dynamics, as it facilitates improved supply chain management, allowing suppliers to adjust production based on real-time demand insights provided by the retailers. Accurate sales data helps suppliers understand trends, stock levels, and customer preferences, leading to better inventory management and more informed decision-making.

Meanwhile, the other options, although they describe potential benefits of scanner technology, do not capture the primary advantage in the context of the question. Storing data, while important, does not convey the immediate impact on retail-supplier relationships. Eliminating manual inventory management is a useful application but does not specifically address the data-sharing aspect. Instant analysis of customer behavior represents a benefit of data processing but does not encapsulate the core advantage of facilitating supplier collaboration through shared sales insights.
