Benefits of credit cards
The biggest function of credit card is to spend in advance, which allows you to spend first and then repay, and there is a long interest-free period. Different banks have different interest-free periods, generally 26-56 days. During the interest-free period, the money can be used to make financial investment and earn interest, and there is no need to feel pressure for a large expenditure. Some people say that this earns less, but it earns less. The bigger the amount, the more you earn.
The whole process can be completed quickly with a credit card, without entering a password or taking out a mobile phone. At the same time, it is more comfortable to spend abroad. Credit cards with VISA or MASTER logo don't need to exchange foreign currency when going abroad, which saves the time and cost of going to the bank to queue up for foreign currency exchange.
