All credit cards are swiped to see if the signature is consistent with the signature of the bank card signature document;

If they don't agree, they will be asked to type a password and provide other valid certificates.

The correct method of credit card consumption:

When you swipe your card, please don't put it away from your sight to avoid misuse or theft of the card;

Don't sign blank or unfilled bills at will;

Before signing, please be sure to confirm whether the card number and amount listed in the bill are correct, and pay attention to whether the consumption currency and the amount expressed in words and figures are correct;

When using a credit card, you must sign to confirm the consumption. Generally, you don't need to show your ID card or enter your password. However, please cooperate in the following situations:

(Due to the operating specifications, POS machines in some cities still need to enter passwords. Please enter 6 digits at will. If you spend a lot of money or buy goods that are easy to realize, it is recommended that you enter an accurate ATM private password. )

When the transaction needs to be rewritten or cancelled due to the wrong signing of the bill, please ask the merchant to tear up all the original bills and keep the return voucher given by the merchant to avoid future disputes;

After signing the bill, please confirm that the credit card returned by the sales staff of the special merchants is indeed their own credit card;

After the transaction is completed, please keep the root contact of the signing cardholder for checking with the credit card statement sent by the bank.
