The benefits of credit cards are:

The first benefit is that cardholders can overdraft in advance, which means that sometimes they can use it when they need money urgently but have no money. A credit card overdraft has a certain amount, and as long as you pay it off within the agreed time, it is equivalent to an interest-free loan, which is often useful when buying large items, such as buying a car or a house.

The second advantage is that cardholders can make purchases without using cash. Of course, this advantage no longer has any advantage, but in the era when credit cards became popular, there was no Alipay and WeChat payment, so credit cards also seemed More convenient.

The third advantage is that if you travel abroad, it is much more convenient to use a credit card than to carry a large amount of cash. Even if you go to withdraw money locally, it is far less convenient than swiping the card directly.

The disadvantage of credit cards is that if the cardholder's consumption exceeds his repayment ability, he will easily become a defaulter and all future consumption will be restricted.

Therefore, only if the cardholder is a rational consumer, can he give full play to the benefits of credit cards and avoid the disadvantages of credit cards.
