Major credit cards, such as a MasterCard, usually are issued by banks and have pre-set credit limits. The cards allow card holders to charge up to their credit limit, and pay the balance in full--or make a minimum payment--when they receive their monthly statements. Credit cards are often confused with charge cards, such as the American Express Platinum Card. Charge cards generally must be paid in full each month and don't offer the flexibility of making payments over time.
Visa and MasterCard
Visa and MasterCard are two of the best-known credit cards available. They are accepted around the world for goods and services. Credit limits on the cards can vary widely, from as little as $200 to more than $25,000, depending on your credit score and qualifications.
American Express Blue
American Express is most known for its charge cards, but it does offer credit cards to compete with MasterCard and Visa. The American Express Blue card is an example.
Discover also competes with MasterCard and Visa. Like many other credit cards, it offers amenities such as rewards programs that can lead to free airline tickets and hotel stays, based on how much you charge on the card.
