Write the next sentence in this paragraph:

How to manage your credit cards
Differentiate between charge and credit cards.
Credit cards and charge cards both allow you to charge purchases to the card and pay for it later. However, this is where their similarities end.
Where credit cards allow you a certain credit limit, charge cards have no set limit. Credit cards allow you to carry a balance between months and pay interest on that balance, but charge cards require that the month's charges be repaid in full at the end of each month.
