If you swipe your card continuously or spend too many times in an hour, the bank will think that there is a risk of cashing out or fraud, so as to control the risk, reduce the credit card limit or seal the card. The solution to frequent credit card swiping transactions is as follows:

1, offline POS machines can swipe their cards no more than three times a day, and they can swipe their cards at different merchants. The interval between swiping cards should not be too short, at least twice every half hour.

2. Brush UnionPay POS machines as much as possible, and use less third-party payment POS machines.

3. Keep the consumption voucher at any time after swiping the card. As long as it is a real transaction, even if the bank has any objection to the transaction, as long as the user can provide the consumption voucher, the suspicion can be ruled out.
