Which of the following describes a method that is not used to track transactions today?

• A. Cash handed to a representative in the store
• B. Self-checkouts
• C. Mobile tablets
• D. Handheld devices

Answer: (A)

In modern retail, tracking a sale relies on electronic point-of-sale systems that log every transaction as it happens. Cash handed to a store representative doesn’t automatically generate a digital record or receipt in the POS, so there isn’t an immediate, auditable trail unless someone later enters the details manually. Other methods—self-checkouts, mobile tablets used as POS devices, and handheld devices—are built to capture and record transactions in real time, print or send receipts, and update inventory. So while cash payments can occur, they aren’t a built-in, trackable method for recording transactions today, making them the one that isn’t used for that purpose.
