Credit cards can be swiped without password in the bank, so that after swiping the card, you can directly press the confirm key (you can also enter the password at this time, you can enter it or not) and then sign it.

You can also set a password when you swipe your card at the bank, so you must enter the password and sign it after you swipe your card.

You can also set the amount of money in the bank to more than 1000 yuan. For example, if the consumption is less than 1000 yuan, you can press the confirm key (you can also enter the password at this time, that is, you can enter it). If it exceeds 1000 yuan, you must enter the password.
