Why can't I use a credit card?
1 The status of the main card is abnormal.
The secondary card is attached to the primary card. If the status of the main card is abnormal, such as the credit card being blocked, frozen or stopped by the bank, then the secondary card can no longer be used for credit card consumption.
2 Credit card merchants are limited
If the secondary card is swiped to the merchant on the bank blacklist, it means that the consumer merchant is limited and cannot swipe the card normally. In this case, it is best to change the consumption of another type of merchant or change the payment method, and the transaction may be successful.
3 Insufficient available quota
The secondary card and the primary card share a line. If the main card has no available quota, such as credit card consumption or installment payment, it is naturally impossible to use the secondary card consumption for trading. If you want to spend by credit card, you can only ask the main cardholder to apply for withdrawal from the bank, or repay the credit card and restore the limit before spending by credit card.
Generally speaking, the failure to swipe the credit card secondary card is mainly caused by the above reasons, which can be solved according to the above reasons. In addition, if you still can't solve it, you can call credit card customer service for help.
