To achieve cash withdrawal by credit card without charging interest, there are several common methods to choose from: POS machine cash out: Cooperate with familiar friends or shops, consume through credit cards, the shop pays in cash, and pays 1 -2 handling fee, but the cost of this method is relatively high. Cash out in shopping malls: Scalpers look for opportunities during shopping mall activities. They will help you settle the bill in cash, and you only have to bear the loss of a fraction of the bill. This is a convenient method but may involve gray areas. Cashing out online: requires cumbersome operations, such as first recharging credit card funds to Alipay A, then transferring to account B, then transferring account B back to account A, and finally withdrawing funds to a savings card. The process is complex and potentially risky. Pay for a friend: This is a relatively low-risk approach. You can take advantage of the interest-free period on your credit card, spend the day after the bill date, and then have your friend pay with your card. Although it is not a direct cash withdrawal, it achieves a similar effect.

Please note that these methods may violate your credit card's terms of use and carry risks, including possible additional fees, damage to your credit history, or legal issues. When considering these methods, it is recommended to carefully weigh the pros and cons and try to abide by the credit card usage regulations of formal channels.
