A loyalty card is a tool used by businesses to reward customers for their repeat purchases. Customers receive a card that tracks their spending and offers points, discounts, or special promotions based on their loyalty. This encourages them to return to the same store or brand, fostering a long-term relationship. Many retailers, such as grocery stores and coffee shops, implement loyalty programs to enhance customer satisfaction and increase sales. By collecting data on customer preferences, businesses can tailor their offerings and marketing strategies, ultimately benefiting both the customer and the company.
