The credit card swiping machine failed to consume, but the SMS has notified the deduction. What should I do?

If the above methods (re-printing, inquiry process) fail to find the record of bank card consumption at POS machines, then at about 12 in the evening, tell the cardholder as a merchant that the money just spent will be automatically transferred to his bank card (the probability is about 90%, and 10% may be credited to the merchant's account), and this will happen. Or sign in again and swipe your card again, because even if there is a possibility that 10% of the money will be credited to the merchant's account, the cardholder has not signed the transaction receipt. According to the law, the cardholder has the right to refuse to pay if he doesn't sign the receipt. As a cardholder, in this case, you can pay cash instead, or make another payment. If you find that both payments have been transferred to the merchant the next day, you can choose to refuse to pay one (because the receipt has not been signed yet) or go to the merchant to get one back. After all, a business will not close down because it overcharges you.
