Postal credit card reservation information is the information you left in advance. Its purpose is to help effectively identify bank websites and prevent criminals from using fake bank websites for online fraud. First of all, you need to record a paragraph in the bank in advance (that is, "reserved information"), and then you can log in to the bank's personal online banking, make payment on the shopping website or sign an entrusted payment agreement online. At this time, the reservation information will be automatically displayed on the webpage, which is convenient to verify whether it is a real bank website. If you don't reserve information, the system will automatically prompt you to set it when logging in to personal online banking. After setting up, you can log in to the website again.

Reserved information can improve security, which is a means for banks to improve the security of online banking. Mainly set a paragraph of text as anti-counterfeiting verification information to prevent hacking attacks such as phishing and fake websites. As long as you have reservation information, you can see your reservation information by paying on the default homepage of personal online banking or online shopping.
