Credit card authentication is the need of identity authentication. When you use a credit card to swipe your card, you can only spend it after your identity authentication is successful. If the authentication fails, it means that the payment cannot be completed.

There may be two reasons for cardholder authentication failure. On the one hand, it is the reason for brushing the POS machine, on the other hand, the credit card itself is in an abnormal state.

First, the reason for the POS machine:

1. At present, most pos machines of many merchants are dial-up connections, so it is impossible to conduct consumer authentication if the network is disconnected or the signal is bad.

2. Some POS machines do not support certain special card transactions, such as World Cup credit card, Transformers 4 credit card, Olympic dragon card, etc., and cannot be used on POS machines issued by ICBC.

2. Abnormal credit card status:

There are many common abnormal credit card status, such as card degaussing, card deactivation, too many times of wrong password locking, card exceeding the validity period, etc., which will lead to cardholder authentication failure. This situation needs to be solved by contacting the customer service of the issuing bank.

Precautions:

1, the frequency should be high: get into the habit of swiping your card anytime and anywhere, buy cigarettes and drinks, swipe your card where you can, and the more you swipe your card at ordinary times, it means that the types of swiping cards are rich, the traffic is good, the amount is easy to be raised, and it is not easy to be controlled by the wind.

2. The amount of credit card swiping should be in line with the usual consumption habits: if the amount of credit card swiping is tens, a large number of tens of thousands of credit cards will suddenly appear, which is easy to be controlled by the wind, so the credit card swiping should be gradual, and don't jump from several hundred to tens of thousands at once.

3. Don't be too late: Try not to swipe your card after 10 at night, because according to common sense, most shops are closed.

4, don't be too early: try not to swipe your card before 9 am, because according to common sense, most shops are not open yet.
