Yes. According to the website of Anhui Quanjiao Rural Commercial Bank Co., Ltd., credit cards have interest-free promotions. In this case, the cardholder only needs to pay back as much as he uses. A credit card is a debit card that can be overdrafted, and you can spend it first and pay it back later. Credit cards are mainly a financial management method that consumes first and then repays, using bank funds to consume in advance and enjoy the interest-free period.
