When you apply with a credit card, an authorization capture will be performed to check whether the credit card has enough credit for payment. If the credit is enough, it will temporarily insure the credit of the total price.
You might receive a notification about the authorization capture, however, no payment will be made at that time. Payment will only be processed once you win the lottery. If you do not win the lottery, the insured credit will be released within 4 days after the announcement of the result. Depending on the card company, it may take some time. Please contact your credit card company for details.
