Credit card rewards programs are incentives offered by credit card companies to encourage card usage. These programs allow cardholders to earn points, cash back, or travel miles for every dollar spent on purchases. The rewards can be redeemed for various benefits, such as gift cards, merchandise, or travel expenses, depending on the specific program. Many credit cards have different types of rewards structures, including flat-rate rewards or bonus categories for specific spending, like dining or groceries. Some popular rewards programs include those from American Express, Chase, and Discover. Cardholders should compare options to find the program that best suits their spending habits.
