I bought a train ticket online, and the mobile phone bound to online banking received 7 verification codes. What happened?

Is your computer slow? Then when you click online payment, the phone keeps receiving the verification code because the button didn't come and was released?

You try this. Enter the last mobile phone verification code. If the payment is successful, your mobile phone will prompt you. Then, when you pay at midnight, the order number of the train ticket is formed. . . . .

One of the seven verification codes must be correct. It should be possible to enter the last one.
