Final answer:
Option (b). A loyalty card system rewards customers for their purchasing behavior by providing incentives and allows for detailed tracking of consumer activity.
Step-by-step explanation:
The system being described is a loyalty card program. A loyalty card system is designed to provide rewards and incentives for consumers. In exchange for allowing the tracking and recording of their purchasing activities, customers earn points, discounts, or other benefits. This system encourages repeat business by rewarding customers for their loyalty.
A payment system plays a crucial role in an economy by facilitating the exchange of goods and services for money or other financial assets. A savings deposit is a type of bank account where funds can be withdrawn at a bank or transferred to a checking account, but cannot be directly withdrawn using a check. A smart card is a card that stores a predetermined value of money, which can be used for transactions, functioning similarly to a loyalty card with stored value features.
