What do you mean, the credit card chip can't get electricity? If the IC card of the credit card shows power failure when operating and trading on the POS machine, it is probably because there is something wrong with the chip of the card, which makes the POS machine unable to read the information and conduct the transaction. Customers are advised to contact the issuing bank to solve the problem and reissue a new card.

Of course, it may also be caused by customer operation errors. You should insert an IC chip card in the transaction, and you can't swipe your card like a magnetic stripe card. If the IC chip card is swiped for transaction, it is not easy for the POS machine to read the information, and there will be a situation in which the transaction cannot be conducted due to power failure. In this regard, customers can try to swipe their cards again.

In addition, it is also possible that the POS machine is out of order or the signal is not good, which is caused by communication. After the information is transmitted to the UnionPay server, it cannot be successfully returned to the POS machine, so the transaction fails. You know, under normal circumstances, after the card is inserted into the POS machine, the POS machine reads the information, uploads it to the UnionPay server, and finally feeds it back to the POS machine, so that the transaction can be successfully completed.

In this case, the customer can switch to a POS machine to operate, or go to a place with good signal to trade and change the payment method.
