A charge card is a type of payment card that allows you to make purchases without a preset spending limit. Unlike credit cards, which let you carry a balance and pay interest, charge cards require you to pay off the full balance each month. This encourages responsible spending and helps you avoid debt. Many charge cards also offer rewards, such as travel points or cash back, making them appealing for frequent shoppers. One popular example of a charge card is the American Express Green Card. This card is known for its travel benefits and exclusive offers. Users appreciate the flexibility of spending without limits, as long as they can pay the balance in full by the due date.
