The most important characteristics of a credit card are the card's interest rate, spending limit, and customer service. The interest rate is the amount of money charged by the credit card company on top of the amount of money spent on the credit card. The spending limit is the maximum amount of money available for spending on the card. Finally, customer service is the level of support available from the credit card company in the case of disputes or other customer service related issues.
