Make a credit card. You must first have a credit card. Your 30 and 80 refer to your batch number of cards. Each bank has a different algorithm.

Now if you want to be a credit card salesperson and don’t go to work, there may not be any bank. The bank will want you.

If you have a lot of orders on hand, you might as well act as an intermediary yourself and cooperate with the credit card person to get money faster!
