In Alibaba, different banks have different regulations on the use of credit cards, but the general limit is more than 5,000 yuan. Reasons for limiting 500 yuan:

1. There is a bank card icon (credit card payment) below the goods you buy now, indicating that credit card payment is supported. No matter what the price is, you can pay by credit card as long as it does not exceed the limit set by the bank.

2. There is no bank card icon (credit card payment) under purchase now. Pay by credit card, up to 500 yuan, beyond which you can't pay.
