Generally speaking, a bank credit card has only one yuan, that is, it is a card with no limit. If you want to use it, you can deposit money first and then swipe your card, and then ask the bank to raise the limit in a few months.

I guess it's because you applied in such a hurry that it's difficult for the bank to predict your situation. In other words, you are not qualified to issue cards in the bank, but in the bank's view, you are a potential customer, and it is not excluded that you will be issued cards in the future. In order to catch you, I'll give you this card first, which means you save money and swipe it. They are looking at whether to send you a card, and how much to send according to your consumption.
