Cardholder authentication failure means that the cardholder authentication fails when swiping the card. Generally, this situation will result in the inability to swipe the card and complete the payment.

Authentication failure may be caused by two reasons. On the one hand, it is the card swiping POS machine, which needs to be replaced. On the other hand, the status of the bank card itself is abnormal, such as the card being degaussed, the card not being activated, and the password being entered incorrectly too many times.

1. Problems with POS machines. Nowadays, more and more POS machines require credit card authentication when you swipe your card. If you do not authenticate when you swipe your card, it will prompt that the authentication failed, and you need to authenticate. It can be used. Many merchants don’t understand what this problem is. In fact, it is to submit a credit certificate to make it safer when you swipe your card.

Why is it prompted that cardholder authentication failed?

1. It is caused by the merchant not submitting the authentication in the background.

2. The authentication process also prompts the same.

2. The problem of your own card. Nowadays, everyone has more than one credit card, so many times our own card expires or has not been used for too long, resulting in abnormal status. But have we discovered it in time? As a result, when we swipe the card, it prompts authentication failure and so on.

Also, the validity period of our certificate has expired, causing the status of the card to be abnormal. If you encounter this problem, please contact the customer service of popular cards immediately. Just follow the instructions and continue using it.
