Loyalty cards are an incentive for a customer to keep coming back to the same business. In exchange for their loyalty, customers are offered special product discounts, coupons, and points for merchandise and other rewards. Loyalty card programs are a great way to build trust between you and your customers, which is good for your customer retention. Furthermore, you can keep track of what your customers buy and which products they are interested in.
Customer satisfaction is worthless. Customer loyalty is priceless.
