For today's young people, almost everyone has a credit card, and people have already enjoyed this process of enjoying first and paying later. Because credit cards are not only simple and easy to operate, but also do not occupy funds. With the progress of the times, credit cards are getting worse and worse. How to prevent credit card passwords from being leaked? Do you know that?/You know what? Do you know that?/You know what?

1, don't use easily cracked numbers such as birth date, home phone number, mobile phone number, etc., and it's best to change the password regularly.

2. When spending money by swiping your card in public places, you must get into the habit of using your hands and fences to protect your password when you withdraw money from the bank. At the same time, you should be alert to someone peeking behind you.

3. When handling banking business at the bank ATM, always pay attention to whether there are suspicious devices at the ATM card insertion place, the cash outlet and the top of the ATM. If yes, please do not enter the password, continue to operate, and report the case to the bank and the public security organ in time.
