of course, credit cards can't be repaid. If you want to repay them, you can only withdraw cash first and then repay them, but this requires a certain handling fee. You don't have to pay in the postal savings online bank. Alipay, Tenpay and other repayments will not generate fees, but it depends on which bank to remit. There is a time difference < P > and repayment can be made through a third party, which is convenient. At present, Alipay Wallet supports credit card repayment of more than 3 banks, and a "repayment reminder day" can be set.
Lacarra repays. There is a handling fee, 2 yuan/pen.
I hope my answer can help you.
