What are credit cards used for?

Using credit cards can help accumulate personal credit and facilitate people's daily life. Spending with a card allows us to enjoy the discounts provided by the bank's special merchants, which brings convenience to our consumption. In addition, credit cards can also provide us with the convenience of overdraft consumption, allowing us to satisfy our own consumption desires and flexibly circulate funds.

However, we must repay the credit card on time after using it. Most banks will provide a repayment grace period of 3-7 days. You only need to repay the outstanding amount within the grace period without any impact. However, failure to make timely repayments can have serious consequences. Therefore, we should maintain good repayment habits and ensure that we pay off our debts on time.
