Fake Transfer Slips: How to Verify a Payment Before You Hand Over the Item
Updated 2026-08-13
A seller's guide: how the fake-slip scam works, how to confirm money actually arrived, the warning signs that show up first, and how to remove this risk entirely.
How the scam actually works
The common version: the buyer sends a screenshot in chat that looks like a bank transfer receipt and pushes you to ship immediately — they're about to travel, or the bank is running slow, or something similar. The slip usually looks convincing, because it came out of a photo editor or a site built specifically to generate fake receipts, complete with account name, amount, timestamp, and a reference number.
The other version: they genuinely transfer, but overpay, then urgently ask you to send the difference back before the original transaction is reversed or recalled. You end up out both the item and the refunded difference. What both versions share is urgency — the scammer needs you to decide faster than you can verify.
Verify in your account, never on the slip
One rule covers this: a slip is not proof of payment. The only proof is the balance in your own account. Open your own banking app, look at the transaction history, and confirm the agreed amount actually landed. Don't rely on an SMS alert alone — those can be faked too — and don't trust a screenshot the buyer sent you, however real it looks.
If the buyer claims the bank is delayed and asks you to ship first, the correct answer is to wait. PromptPay and interbank transfers in Thailand almost always land within seconds. A delay measured in hours is abnormal, and when that excuse arrives packaged with urgency, it is the warning sign itself.
The warning signs that come before the fake slip
Scammers tend to behave the same way before the slip ever appears. Be wary of a buyer who accepts full asking price instantly without negotiating or asking a single question about the item — unusual in secondhand, where haggling is the norm. Be wary of anyone insisting on moving off-app in the first few messages. And be wary of brand-new accounts with no transaction history and no verification.
Another sign is oddly specific time pressure: it has to ship within the hour, it has to arrive before noon, it's a gift needed today. Manufactured urgency is the core tool of this scam, because it's what makes you skip the check you'd normally do.
How to remove the risk entirely
The most effective fix is simply not to accept direct bank transfers from strangers. Close the sale through SOI Pay instead: the buyer's money is captured at checkout, so you see the paid status in the app itself rather than relying on an image someone sent you. The money is released to you after the buyer confirms receipt, or after the 72-hour auto-release following successful delivery.
The fake-slip scam simply doesn't work against this, because payment status comes from the system rather than from what the buyer tells you. If a buyer insists on transferring directly to your account and refuses to pay through the platform without a reason that holds up, treat that as the answer.
What to do if it already happened to you
If you've already shipped and the money never arrived, preserve everything immediately: the full chat, the slip image you received, whatever account details the buyer gave you, the tracking number, and the timestamps. Don't delete the conversation or block the user before you've saved it — you'll need all of it both for the in-app report and for a police report.
Then report the user in the app so they can't run the same play on the next seller, contact your bank to flag the incident, and file a report at a police station or through the online channel for technology-related crime. The faster it's reported, the better the odds the receiving account can still be frozen.
Frequently asked questions
Can a slip with a reference number and a verification QR be faked?
Yes. Every visible element on a slip can be reproduced, including reference numbers and QR codes that look like verification links — those can point at a fake page the scammer built. Never treat anything printed on the slip as confirmation. Open your own banking app and read your own transaction history.
If we meet in person and they transfer on the spot, am I still at risk?
Yes. The most common in-person version is showing you their banking app screen and taking the item while you're still looking. Open your own banking app in front of them, wait until the credit actually appears in your transaction list, and hand over the item after that. Waiting an extra minute isn't rude, and an honest buyer won't have any problem with it.
A buyer overpaid and wants the difference back — what should I do?
Do not send it back. This is a standard scam pattern — the original transaction can be recalled or reversed later, leaving you out both the refund and the item. Contact your own bank and let them handle the misdirected-payment process, and tell the buyer to raise it with their bank too. Don't settle it privately between yourselves.
Is there any fake-slip risk when selling through SOI Pay?
No, because you never look at a slip. Payment status is shown in the app and comes from the payment system, not from an image the buyer sent. Fake-slip risk exists only with direct bank transfers outside the platform.
