Are you going to start this business? Or go to the bank to get a credit card?

First of all, if you are a bank clerk, you need to develop this business, so it is very simple. Every bank's bank card center will have a credit card department and its own team. Someone will teach you when you go in, and you will learn quickly. It would be much easier if you just have a headache and don't know where to start this business. Go where there are many factories, where there are many office buildings, and to the gate of the industrial park. There's a lot of people there. You can set up a booth and start work first.

If you want to ask what to do with credit cards. That's easier. Go directly to the bank and provide proof of salary (income). Employment status, social security certificate, ID card and other documents will do. Banks have certain procedures for opening bank cards. After the information is delivered, it needs to be reviewed. After the bank reviews, the card can be issued. After you get the card, you can open it step by step according to the instructions. No trouble.
