Because that Tmall seller doesn't have a credit card payment function, and your credit card exceeds the monthly free quota, a 1% handling fee will be charged for the excess amount. On the Alipay payment confirmation page, you will be prompted with the option of "Agree to pay 1% handling fee". If you don't check it, you can't use the transportation credit card to pay.

not all tmall sellers support credit card payment. most tmall sellers support credit card payment, and a few tmall sellers do not. Tmall sellers who do not support credit card payment generally do not provide regular machines to invoice buyers.

Pay by credit card. If the seller doesn't activate the credit card payment function, the buyer can enjoy a free monthly 5 yuan/card limit, and spend within the free limit without handling fee. If you spend more than the free amount, you will be charged a 1% handling fee if you don't have a replaceable credit card to pay.

therefore, if the free credit card payment quota is used up, please choose Alipay or savings card to avoid handling fees.
