More money was withdrawn than the amount I tried to charge.

When you charge points using simple payment services like Toss, Naver Pay (Npay), or Kakao Pay, you might see a withdrawal that’s larger than the amount you intended to charge. This is not a payment error, but a situation where points were charged using the service’s prepaid top-up method.

• If your balance within the service is insufficient at the time of payment, a preset minimum amount (e.g., 10,000 KRW, 50,000 KRW) is automatically topped up first, and then the payment is made.
• The remaining money after the payment does not disappear; it is stored as a balance within the simple payment service. 

Please check the remaining balance within each service after top-up by referring to the information below.

Toss Pay

• After accessing Toss, go to [All Accounts] > [Points/Pay Money] and check whether the remaining amount after charging POSTYPE points is stored as Toss Pay Money.
• If the balance is insufficient, 50,000 KRW will automatically be topped up and then used for payment, and any remaining amount after the top-up is kept as Toss Pay Money.
• From Toss Home > top right [Payment] > [Payment Methods] > [Settings] next to Toss Pay Money > [Transfer], you can select the account and amount to withdraw the remaining balance.
• For more details, please contact the Toss Customer Center directly. 

Naver Pay (Npay)

• On Naver, go to [Npay] > [Points] > [Money] and check whether the remaining amount after charging POSTYPE points is stored as Npay Money.
• If you use the ‘Scheduled Top-up’ feature of Npay Money and your Npay Money is insufficient, Npay will automatically top up the designated amount from the linked account and then use it for payment.
• If a top-up payment is canceled, it is refunded as Npay Money, and the refunded Npay Money can be withdrawn to your bank account without any fees.
• For more details, please contact the Npay Customer Center directly.

Kakao Pay

• In the KakaoTalk app, go to the bottom [···] (More) > [pay] > tap [Money Balance] > [Money History] and check whether the remaining amount after charging POSTYPE points is stored as Pay Money.
• According to Kakao Pay’s policy, if your Pay Money balance is insufficient and a bank account eligible for top-up is registered, Kakao Pay will automatically top up Pay Money in units of 10,000 KRW and use it for the payment.
• For more details, please contact the Kakao Pay Customer Center directly.
