The credit card information verified when binding or paying online is basically the card number, expiration date, and the CVV2/CVC verification code on the back of the card. There may also be a SMS verification code. The card number and expiration date are both engraved on the front of the card. If the expiration date is, for example, 05/20, it means it expires in May 2020. When entering it on the web page, just enter 0520. The CVV2/CVC code is the three numbers to the right of the signature on the back of the card.
