Reasons for failure of verification of four elements of bank card:

The main reasons for the failure of bank card four elements verification are as follows.

1, bank card information input error, this situation is generally caused by bank card information input error or fill in the wrong reasons.

2. The bank card is in an abnormal state, and it cannot be checked if it is expired, frozen or cancelled.

3. The bank card does not exist. In this case, the bank card may be forged, and the UnionPay system database does not have this record. That is to say, the bank has no card data record of this card.

4. The data source network changes, and the network changes are various, which are related to factors such as machinery room, database and operators. The network changes are small probability events.

5. The data has not been updated to the general database. After the cardholder changes the information, the banking system has not updated the data to the UnionPay General Administration, so it is necessary to contact the person in charge of the platform for handling.
