The first thing to understand is that when grabbing tickets, the system will first verify the inventory and determine the payment after the ticket is available. Therefore, if there is a prompt that the credit card is being swiped, it may be that the system detects that your credit card is being paid, but it has not been completed yet. At this time, you need to wait for a period of time and re-enter the ticket grabbing process to submit payment after the payment is completed. At the same time, you can also contact the bank customer service to check the payment situation, ensure that the credit card account has enough balance, or check whether there are any abnormal operations that lead to payment failure. It is suggested to make preparations before payment when grabbing tickets, including maintaining good network stability, ensuring the accuracy of credit card authorization and payment password, and avoiding unnecessary payment problems.
