Credit cards operate differently from other loans both in the way they are paid, but also in the terms they use. For a car loan example, the payment due date will advance as soon as a payment is made to the next projected payment date. This is known ahead of time because the loan is a monthly recurring payment for the same amount. Credit cards, however function a bit differently because the payment is going towards the balance owed 'after the fact' and the amount due will fluctuate every month based on use.

With an amortized loan, the payments are going towards the next payment before it is due. With a credit card, the payment is applying to activity that has already occurred, but given a specific deadline and amount to fulfill.

The due date on the card is a specific date of any given month and remains constant. That is to say that even if a payment is made, the minimum amount was still due on or before the date shown. This field will instead change as soon as the next VISA statement comes out. The next statement is also where the payment is documented - it is occurring in the next statement period. When that next statement comes out, the due date will advance and the new minimum will be calculated based on any payments made and the new card balance.
