What is a Cardmember Agreement?

Also known as a "cardholder agreement," this is the legal document containing the terms and conditions of the contract between the card member (cardholder) and the credit card issuer. It explains the details of the credit card, including but not limited to the card's APR, how interest is calculated, how the minimum payment due is calculated, and, if it's a rewards credit card, which purchases are eligible for rewards, how rewards are earned, how they're redeemed, and more.
