Cash cannot be deposited directly into a credit card, but the money on the credit card can be transferred into cash through some channels.

One way is to use an ATM machine, which allows you to transfer money from your credit card to a bank account and then withdraw cash from the bank account. However, due to the credit card's withdrawal limit, the amount of each withdrawal is limited, and a certain handling fee will be charged for each withdrawal.

Another method is through online banking, where you can transfer money from your credit card to a bank account and then withdraw cash from the bank account. This method is more convenient than an ATM machine and has no withdrawal limit, but it will also charge a certain handling fee.

In addition, you can also transfer money from your credit card to Alipay or WeChat wallet through a third-party payment platform, and then withdraw cash from Alipay or WeChat wallet. This method is more convenient than ATM machines and online banking, and there is no withdrawal limit, but it will also charge a certain handling fee.

In short, credit cards can transfer money into cash through ATM machines, online banking and third-party payment platforms, but a certain handling fee will be charged for each transfer.
