In the Internet of Things example, which application provides insights into spending patterns?

• A. Tesco Clubcard usage providing insights into spending habits
• B. A standalone cash register with no network
• C. A mechanical scale without sensors
• D. A manual ledger on paper

Answer: (A)

The key idea here is that IoT-enabled systems gather data from connected devices to feed analytics that reveal how customers behave, including how they spend. Tesco Clubcard usage collects purchase data across shoppers and transactions, creating a rich dataset about what people buy, how much they spend, when they shop, and which categories they prefer. Analyzing this data uncovers spending patterns such as average basket size, frequent product sets, and seasonal trends, which can drive targeted offers and inventory planning. The other options lack connectivity, sensors, or digital data flow, so they don’t generate actionable insights about spending in an IoT context. So Tesco Clubcard usage provides the relevant spending-pattern insights.
