The cardholder's identity authentication failed probably because your card has been degaussed. Try another card.

First, the identity authentication of the credit card holder failed

This situation often occurs when swiping a card on a pos machine. The cashier needs to verify the identity of the cardholder when operating our credit card at POS. Only after the authentication is successful can the credit card be used for consumption. However, the POS machine prompts the cardholder that the authentication failed, which means that your credit card cannot be swiped and the payment cannot be completed. You need to change other credit cards or pay directly in cash.

second, we need to find out the reason of authentication failure, and then solve it.

when swiping the card, the machine displays authentication failure. In this regard, we should consider whether your card is abnormal, whether the new card is not activated, whether the consumption authority has not been opened, or whether the old card has expired. The failure of cardholder authentication should be a problem when swiping the card. At this time, we can see from these aspects:

1. This is the error code returned by UnionPay. Generally, you can only change your card.

2. Check the card status, whether the magnetic stripe card is often placed with the metal mobile phone, whether it is an inactive card (here refers to the credit card), whether the password on other machines on that day is locked due to too many mistakes, and finally whether the check card has expired (here refers to the credit card). Finally, you need to call the bank customer service to confirm.

3. Check the card swiping machine. Traditional machines are also connected through mobile networks. If it is in a place with poor signal, it will also fail if the returned data is not received.

4. Check whether the card is a single currency overseas card. Some cards issued by banks have no UnionPay logo, only visa or MasterCard logo. This card can't be used on home machines.

if the above four conditions do not exist, it is recommended to change the machine and swipe the card. If not, apply for a new card.
