First, the cardholder's personal behavior, the cardholder plays the trick of "others spend their own cards", swipes other people's shopping accounts into their own cards to increase points, and at the same time, the shopper returns the cardholder's cash, which can kill two birds with one stone for the cardholder. Because many banks launched value-added services while issuing credit cards, and carried out activities such as exchanging consumption points for gifts to stimulate people's enthusiasm for card consumption.

Second, cardholders cooperate with merchants or some "loan companies" and "intermediary companies", and cardholders get cash by paying fees to merchants. Generally, the merchant's POS machine is used to make false transactions, and the amount on the credit card is crossed out. Merchants or "loan companies" and "intermediary companies" pay cash on the spot (paying cash to cardholders), and the handling fee paid by cardholders to merchants is lower than that of banks.
