If Money Sent Through a Quick-Transfer App Was Voice Phishing, Ask the App Operator as Well as the Bank for a Payment Freeze
If money you sent through a quick-transfer app such as Kakao Pay or Toss turns out to be voice phishing, who do you contact first? Thinking only of bank transfers makes this confusing. Recent reports said that payment freezes on voice-phishing money routed through quick-transfer services at the five major banks reached about 3,000 cases in the first half of this year, 3.5 times last year (a 250% rise), and that the "small amounts, many times" method is spreading. Based on the relief procedure set by the Telecommunications-Based Financial Fraud Act, this post lays out the order of reporting for money sent through quick-transfer apps. Amounts and processing times vary by case, and this is not legal advice.
Why quick transfers are so often used in voice phishing
Quick transfer lets you send money with only a phone number or a link, with no certificate, which is why scammers like it. Victims often open the app and follow instructions to send money to a "safe account," and the money then passes through a prepaid-service provider (the app operator) and bank accounts and is scattered quickly. Splitting the money into small transfers also helps it slip under single-transfer limits and abnormal-transaction detection.
Since August 28, 2024, prepaid providers have had to share information too
According to the Financial Services Commission's guidance, the amended Telecommunications-Based Financial Fraud Act took effect on August 28, 2024 and created an obligation for financial companies and prepaid-service providers to share information on accounts used for fraud. Before, it could take one to two months after a relief application for information to move between them; now it is meant to be processed faster. In other words, going through a quick-transfer service does not take you out of the relief system.
Small amounts, many times are easy to miss one at a time. The "small amounts, many times" method the reports highlighted means being made to send tens of thousands to a few hundred thousand won in several rounds rather than one large sum. Victims do not feel a big loss on any single transfer, so reports come late, and in the meantime the money is moved to other accounts. If several transfers went out, do not treat them one by one; group them as one case and report them all on the same day. Giving the time of the first transfer, the time of the last and the total amount speeds up intake.
The order of reporting: ask for the payment freeze first
The first thing to do is tell the customer center of the place the money left from, "I suspect voice phishing and request a payment freeze." If you sent it from a quick-transfer app, notify that app's operator; if it left from a linked bank account, tell that bank as well. If you do not know whom to call, you can ask the Financial Supervisory Service at 1332 or the police at 112 and be connected. Time matters most for a freeze, so call first and gather documents afterward.
After the freeze, the steps are the same as for bank transfers
After a freeze is placed, the order of filing a damage-relief application, the public notice on extinguishing the claim and the refund decision is the same as for a bank transfer. The deadlines for each step are laid out in our guide to refunds after a voice-phishing freeze, so read that first. This post concentrates on what differs for quick transfers: whom to contact and how the accounts are structured.
What to know if your own account is suspected of being a fraud account
Sometimes you receive money in a second-hand sale and your account is suddenly blocked. If you submit supporting documents, the guidance says you can find out whether the freeze is lifted within five business days. Keep the transaction chat, the transfer records and photos of the item.
Records financial companies keep and documents victims should save
Financial companies must keep records of temporary measures and identity-verification measures for five years. As a victim, collect screenshots of the transfer screen, the other party's number and the messages or chat, and your report reference number. A police report confirmation makes later applications easier. App transaction history can become hard to look up as time passes, so saving it the same day is safer.
What victims should not do before reporting. Secondary harm is common, with scammers demanding that you install an app so they can "return your money" or pay a "refund fee" first. If you feel you have been deceived, end the call and make no further transfers or app installs. Calling the other party back to argue also risks erasing evidence. Contact only the app's official customer center, 112 and 1332.
Prevention: transfer limits and account settings
In quick-transfer apps, lower the per-transfer and daily limits, and never open links sent from unknown numbers. To check whether a line was opened in your name without your knowledge, see the mSafer guide, and for mobile micropayment problems see blocking the carrier-billing limit.
Summary of the order
1) Immediately ask the app operator and the bank for a payment freeze. 2) Report to 112 or 1332. 3) Keep screenshots and chats. 4) After the freeze, file the damage-relief application. 5) Apply for the refund according to the procedure the financial company gives you. The figures in the reports come from Yonhap News and Maeil Business articles of October 2026, and the law and procedure follow the Financial Services Commission's guidance. This is not legal advice, so confirm specific cases with the Financial Supervisory Service and the police.
