Why can't I find the pos machine of Zhongyintong payment card?

The reasons why the pos machine of Zhongyintong payment card cannot be found are as follows:

1, network reasons, when swiping the card, because of network reasons, the transaction actually didn't succeed. You can go to the issuing bank to see if there is running water, or directly check whether there is this bill on the mobile banking APP.

2. The data did not return to the POS machine. That is to say, although they all received the information of deduction, but the actual transaction settlement was unsuccessful, the deduction will be returned to the user's original account within one hour.

3. The payment was unsuccessful. Although the notice of deduction has been received, it is actually an unsuccessful payment. The money withheld by all of us was temporarily left in the bank, and now it is handled through the bank.
