How Credit Cards Work
The issuer of the card will set a credit limit or line of credit to it holders, which determine how much the holders can borrow for payment to merchant or for Cash withdrawal via ATM in the form of cash advance

The issuer will bill the holders at the end on the billing cycle on monthly basis. The card holders must pay the bill in full or at least a minimum payment before the due date as agreed.

However, if John only paid $400 or which mean $100 unpaid, interest would be calculated or charged until full payment or settlement. The interest charges and other details usually can be found in the cardholder agreement documents.

Most of the time, the cards holders will enjoy lower interest rates for the transfer and also can be converted into monthly repayment (tenure). This is beneficial for card holders who has a huge outstanding amount.
