The answer is yes. Credit cards don't need a password.

A credit card can be used without a password, but the following matters should be noted:

1. In international practice, it is common to use my signature instead of a password. Because the password can be stolen but the signature is unique, foreigners are used to using a credit card in the form of a signature.

2. When applying for a credit card in China, you can choose a signature instead of a password on the application form, but the general bank will prompt you to set a password, because it is a common practice to use a card with a password in China. When using a credit card in a card-using environment such as banks, self-service banks, shopping malls, hotels and supermarkets, the staff will prompt you to use your password. Using the card only by signing it may lead to the inability to check, which will lead to great risks during the card use.

To sum up, although credit cards can be signed without setting a password, it is recommended that you set a password in the market environment of China.
