When swiping the medical insurance card, it prompts that the cardholder authentication failed

Hello dear, when swiping the card, it shows that the cardholder authentication failed. There are many reasons why the card cannot be swiped. Generally, there are the following categories: First, the card status is abnormal, such as the card is degaussed or the card is not activated. , the password has been entered incorrectly too many times and has been locked, and the card has expired. It is recommended to call the CCB customer service hotline to confirm; second, there is no problem with the card, but the POS machine signal is not good, and the card cannot be swiped if it is not connected to the network; third, If the cardholder holds an IC chip credit card, because UnionPay has turned off the downgrade transaction function, if the cashier still operates the transaction by swiping the card instead of inserting the card, it will also be unusable.
