There are several reasons for not receiving the password letter:
1. The credit card center did not send the password letter. It's been so long. Generally speaking, it is impossible. You can call 8008200588 or 02 1-50504750 to check the delivery of your password letter.
2. The password letter is lost. The postal delivery process may be lost. Please repeat the above steps to confirm whether it is lost. The password letter is a registered letter, and you can check the whereabouts.
3. Being impersonated by others. Call to confirm that the password letter has been sent, and make sure that the registered letter has arrived, but you can't receive it, then it is likely that someone has impersonated you and needs to ask the credit card center to resend the password letter.
The question of password or signature has been debated for a long time, and I don't want to put an end to this debate here. However, from a global perspective, with the promotion of e-commerce, the general trend is that passwords replace signatures, and credit card companies such as MasterCard and Visa are trying to promote password authentication. But in the end, which risk is greater, the situation in each region is different, and personal habits are different. Everyone has a different name in mind. What I can do is to provide as comprehensive information as possible and let you make your own judgment. There are many arguments about such topics, and customers often encounter this dilemma. For example, regarding the validity of the mail delivery contract, I can only say 1) It is better to plan ahead than to seek compensation after suffering losses; 2) Science and technology promote development, and we have to adapt. If the rules do not conform to the development trend, the rules will have to be changed.
In general, you need to enter the password by default when applying for a credit card, but you need special requirements when paying without a password. If the credit card can still be traded with the wrong password, it means that it is set to trade by signature under a certain limit, so when you ask for the password, you can swipe the card successfully by pressing 6 digits casually. If the cardholder feels unsafe, he can call the customer service hotline to make corrections.
In order to avoid this problem, when filling in the column of "Customized Personalized Service" in the credit card application form, pay attention to a small line next to "Consumer Password" below. "If it is not checked, it will be regarded as confidential, and the initial amount will be 0". Just leave it unchecked. If this column is not checked, the payment method is "password+signature" by default. However, if you want to choose not to enter the password, you can check "Yes" and fill in the corresponding number after "Starting Amount", which means that you can complete the transaction by swiping your card within the limit.
