In contrast, signature is more secure, because the password is at risk of being stolen and the handwriting of the signature is difficult to imitate. Domestic credit card payment generally does not require a password, of course, using a password is more reliable. When you use the password, the merchant will also ask for your signature, which is equal to double insurance. When you use a credit card abroad, you don't need a password, but you need the cardholder's signature, so you can't tell others your signature to avoid being imitated.

Precautions for credit card use

1. If you receive the issued credit card, please sign it as soon as possible, and please note that the signature on the back of the card must be consistent with the signature of the application form and the signature of the future consumption bill.

2. You can use "signature" or "password+signature" to swipe your card at will. It is recommended that you choose a more secure "password+signature".

When you make a transaction with a credit card, once you confirm your password, it will be regarded as my transaction. Therefore, when you need to enter a password for credit card consumption or cash withdrawal, you should cover your operation posture with your body or your other hand as much as possible to avoid being snooped by criminals and causing the danger of misappropriation.

When pressing the card, please be sure to verify the stamp and handwriting on the card pressing form. Don't sign the blank or incomplete information card form.
