Why do some POS machines swipe their cards and don't receive information?

The receipt inquiry is conducted through the online banking process. Sometimes UnionPay will occasionally transfer money or delay for a long time without SMS reminder. You can't judge whether the funds are in place in full by SMS. You can check the flow of your account in the bank official website or in the background of the APP.

2. The 2.POS machine failed to issue a receipt, and the transaction was unsuccessful:

After swiping the card, occasionally the POS machine does not send a receipt, and the cardholder receives a debit message from the bank. In fact, as long as the POS machine does not issue a receipt, the whole transaction will not be completed, and the cardholder's deduction will be returned to the account within 48 hours. In other words, the customer did not succeed in spending on the POS machine at all.

3. Distinguish settlement time:

If the settlement method is T 1, it will arrive on the next working day. Note that it is a working day, that is, Friday, Saturday and Sunday transactions arrive on Monday, and holidays are postponed. In addition, the post-holiday settlement volume is relatively large, and the account will arrive later than usual.

In addition, whether it is swiping the card to t0 or T 1, if the swiping time is very late, this transaction may be counted as the next day's transaction, so you can wait patiently for its arrival.

4. Error in binding settlement card:

This situation is very rare, because if the settlement card is incorrectly bound, the first transaction can be found. This situation can be eliminated as long as it is successfully received. For the background operation problems raised by customers, if it is a clearing platform, regular agents can provide the background for customers to inquire. In the background, you can clearly see who the bound bank card number is.

5. Calculation error:

This situation is really common. A friend swiped it several times and then miscalculated the account. They think there is something wrong with the arrival of the account. Therefore, if in doubt, you'd better check the receipt and bank flow to determine whether there are any mistakes.

6. The use of secondary cleaning machine:

The bank has settled the card payment to the payment company, but the payment company has not settled with the merchant and credited it to the bank. This situation only happens in the second payment company, and the first payment company will not happen because it is supervised by the People's Bank of China and UnionPay. If the above reasons can be ruled out, you need to confirm whether your machine has been cleared. The method is simple. Check with the central bank whether the POS payment platform has the receipt conditions, or ask the agent to check the binding settlement card in the background.
