Why does the bank card receive the information of deduction?

1. Personal information kept by individuals is incorrect. When we apply for a bank card, we all need to provide personal information such as personal ID card and mobile phone number under our personal name for registration, but some people will change their mobile phone number or personal ID address, so this is inconsistent with the personal information reserved by the bank, so the bank cannot match the correct personal information, so it will send a text message to remind us. At this time, we only need to bring new personal information to the bank counter to change the information. 2. No personal real-name authentication. Before returning to China, a lot of personal information under a person's name was not very clear, so it is possible that he had a bank card under his name, but he was authenticated by his real name. Therefore, in order to reduce risks and improve the security of personal information, banks will remind users to carry out real-name authentication, and only need to bring their ID cards to the bank counter.
