The reason why a credit card can only swipe 500 yuan at a time is: the credit card’s single consumption limit is set to 500, and users can try to change the single consumption limit; the merchant’s static QR code limits the consumption limit to 500 yuan. Users can use POS machines to swipe their cards for consumption, or go to different places to swipe their credit cards for consumption, so that the limit will be lifted.

Therefore, the credit card limit of 500 can be lifted at a time. As long as the user knows what causes the limit, the solution is relatively simple.
