Alipay has begun charging service fees for credit card balance payments. For payments under 2000 yuan, it’s still free of charge, but when exceeding 2000 Yuan, a service fee of 0.01% is charged.
For example, if a user repays a credit card balance of 10,000 Yuan by Alipay, after deducting the free-of-charge amount, an additional 8 Yuan will be charged as a service fee.
The free repayment amount of 2000 Yuan is issued according to the natural month, i.e. 00:00 on the first day of each month, and the unused free repayment amount is cleared at 23:59:59 on the last day of each month.
It is worth mentioning, that any remaining free repayment amount does not transfer to a new month, and a user can upgrade the amount by spending Alipay membership points.

Why Did Alipay Start Charging a Fee?
In fact, as early as last July, WeChat Pay announced that starting August 1st, every credit card repayment via Wechat would be charged a service fee of 0.1%.
With regard to the above fee standards, Wechat explained that there was actually a payment channel fee behind every repayment. In order to enable users to enjoy part of the free product experience, Tenpay had been investing in fee subsidies. However, in past years, with the rapid development of the credit card repayment business, the cost of channel charges had begun to rise.
Similar to WeChat, Alipay also explained in February 21st 2019, that the reason for the charge was “the rapid increase in the cost of comprehensive operation”.
