I'm not sure how it works for Bank credit cards, but probably about the same as it did for a store credit card. I had to apply for the credit card at the cash register. The cashier had me fill in some stuff and then you are either accepted or denied. I was denied, so I paid with another card and went home. Ten days later, I got my card in the mail. I had to take the card to the store and buy something with it and upload the receipt. I also had to upload copies of the credit card agreement, the envelope the card came in and a lot of other stuff from that envelope. I had to charge something online on the store's site, I had to call customer service and ask a question, and the next day, send an email to customer service asking a question. I had to upload my first bill, return something and then upload a copy of the statement showing the return.
It took about 6 weeks total, and it was a little tedious, but the pay was really good and the work was minimal when broken over that much time.
