Guangzhou Bank app can now bind credit cards, one is to go to the bank to handle related business, and the other is to actually go to Guangzhou Bank to handle this business in official website. When you go to official website, official website will give you some tips and methods, which will allow you to authenticate your real name, then enter most personal information, and then go through the process. It is better to go to the bank counter for business change than to go to official website. When you go to the bank to handle related business, you can ask many questions. When you go to official website, you can only go through the process. Personally, I suggest going to the bank to handle related business. To bind in official website, Guangzhou Bank outlets can also be used.
