What are the different levels of credit cards available and how do they differ from each other?

There are typically three levels of credit cards: basic, rewards, and premium. Basic cards have no annual fee and offer standard benefits. Rewards cards offer cash back, points, or miles for spending. Premium cards have higher annual fees but offer more perks like travel benefits and concierge services. The main difference is in the rewards and benefits offered, with premium cards providing more exclusive perks.
