Small transactions, such as 1 JPY or 100 JPY, are processed in accordance with the "1 JPY authorization" policy of the payment service provider.
"1 JPY authorization" is conducted to verify if the registered credit card (including debit and prepaid cards) can process payments by debiting small amounts like 1 JPY or 100 JPY.
This method is solely used to verify the validity of the registered card, including checking for sufficient balance and expiration date. There are no actual charges incurred by the user.
*However, for debit cards and prepaid cards, the amount will be deducted from the card balance as "1 JPY spent" and automatically refunded shortly thereafter, typically within a few days or months.
