đź’ˇ In a nutshell

You can use debit and prepaid cards on if.

However, because crowdfunding has a unique payment flow,

you may occasionally see duplicate charges or delayed refunds.

For this reason, credit cards are recommended whenever possible.

â‘  Supported Card Types

You can use Visa, MasterCard, and JCB branded

debit cards and prepaid cards on if.

However, since these cards process funds differently from credit cards,

you may experience temporary “double charges” or longer refund times.


② Differences Between Credit, Debit, and Prepaid Cards

Type Credit Card Debit / Prepaid Card
Timing of charge Billed later (after confirmation) Immediately withdrawn
Authorization (pre-approval) Temporary authorization → Final charge later Immediate charge, then later re-authorization or cancellation
Risk of double charge Rare Possible temporarily
Refund speed Instant to a few days Several days to weeks possible

💬 What is “Authorization”?

💡 It’s a temporary hold that confirms the card is valid for the payment.

The actual withdrawal happens later when the payment is finalized.
