What is the significance of scanning all items during checkout?

Scanning all items during checkout is crucial because it ensures that every purchase is accurately tracked and priced. This process helps maintain inventory control and financial accuracy, allowing the store to know exactly what items are sold and how much revenue is generated. It also prevents discrepancies that could lead to financial losses or customer dissatisfaction if they find that they were charged incorrectly or if stock levels do not match actual sales. This practice ultimately enhances the overall shopping experience for customers, as they can trust that they are being charged correctly for their purchases.
