If the landlord is the main card, the credit line is sufficient, or the card status is abnormal, or the credit card network is abnormal, so it is impossible to swipe the card. If the status is abnormal, call the service hotline to confirm the actual situation of the card. If the credit card network is abnormal, we can only wait for the credit card machine signal to recover or the online trading platform to resume normal use.
If the landlord is a sub-card, what you find on this page is the limit of the main card, not the limit of the sub-card, which is probably caused by the insufficient limit of the sub-card (mainly because the main card set a limit for the sub-card when handling the card, and the sub-card almost used up the limit, which has been restored once in a billing cycle and has not been automatically restored yet). In this case, the principal cardholder can call the banking service hotline.
