After applying for a credit card, we can swipe the card for consumption, which is very convenient. However, if there is still a balance on the card but the card cannot be swiped, there may be the following reasons.

1 The card is not activated: When we apply successfully or replace the card, we need to activate the card. Without activation, it cannot be used.

2 The chip is damaged: We can go to the counter of the card-issuing bank's branch to try the card. If it is confirmed that the chip is damaged, we can go directly to the counter or call the bank's credit card hotline to apply for a card replacement.

3 Card freezing: The bank system monitors credit cards. If any abnormalities are found in the credit card, the system will freeze the credit card to reduce the cardholder's losses. You can call the customer service hotline or bring your ID card to the bank for unfreezing procedures.

4 Card expiration: The validity period of a credit card is generally displayed on the card. If it is found to be expired, we can directly call the bank's credit card hotline to renew the card.

5 Transaction risk: When swiping a credit card for consumption, if the bank detects that the transaction is risky, in order to prevent the risk, the bank will not allow the credit card to complete the transaction, resulting in the credit card being unable to swipe the card for consumption.

6 Transaction limits: Credit cards have daily transaction limits. If the card is swiped too many times that day and the daily limit of the credit card is reached, the credit card will not be swiped when the card is swiped again.

7 Machine failure: When the POS machine line is busy or fails, we can try again later, or use other methods to pay.

The above is about the reasons why the credit card cannot be charged and the corresponding solutions. We can investigate based on the above reasons. If we cannot confirm, we can also directly call the customer service hotline of the card issuer for consultation and help.
