Although many people have passwords in daily credit cards, the risk of password leakage will increase with the increase of credit card usage. Therefore, credit card endorsement should be a more important security measure than password. However, in real life, most merchants do not carefully check the endorsement, and cardholders do not pay attention to it, which brings hidden dangers to the safety of credit card consumption.

Here, we suggest that you should sign a back signature before using the credit card. In this way, if the credit card is stolen in time and the merchant settles the account without checking the signature, the seller will bear the risk of stolen credit. If it is stolen without signature, the responsibility lies with the cardholder. At the same time, I also suggest that you use your credit card reasonably and don't overdue it, so as not to affect your credit history.
