Yes The continuous code scanning of the same merchant's credit card is easy to be controlled by the wind, and it will be detected as an abnormal transaction by the banking system, so there will be a situation where there is a limit in the card but payment is not allowed, so the impact is great. The cardholder can change another credit card to pay, or change another merchant to scan and pay by QR code. Matters needing attention when paying by credit card:

1, don't always use the integral multiple of 10 or 100 for spending.

2. Diversified consumption bills, so don't spend money in one place often.

3. The card swiping time should be within the business hours of the merchants as far as possible. Frequent swiping in the morning will trigger the risk control system.
