Why shops use it
Catches edited slips
Every slip QR carries a checksum. A QR that was changed or made by hand fails it.
Warns about re-used slips
The transaction reference is remembered, so the same slip sent twice is flagged at once.
Private by design
The picture is read in your browser. Only the QR text is checked — the slip image is never uploaded.
Free, every bank
Works with slips from KBank, SCB, Bangkok Bank, Krungthai, Krungsri, ttb, GSB and other Thai banks.
How to check a slip
Save the slip picture
Use the original screenshot the customer sent, not a photo of a screen.
Drop it on this page
Choose, drag or paste one or more slips. Each one is read in a second.
Read the result & check your account
Green means the QR is genuine and new. Then confirm the money arrived in your bank app.
What a slip check can and cannot prove
A Thai bank slip has a small verification QR with the sending bank and a transaction reference. Reading it shows whether the QR is untouched and whether the same slip was seen before — the two most common tricks with fake slips.
Only the bank can confirm the amount and names. Shops with a SlipOK account can add their key in Dashboard → Payments to have each slip confirmed with the bank. Either way, the money showing in your own account is the final proof.
Questions
Is the slip checker free?
Yes. Reading the QR, the edit check and the re-used slip warning are free. Bank confirmation uses your own SlipOK account.
Can it tell me the amount on the slip?
The slip QR does not contain the amount. To get the real amount from the bank, add a SlipOK key in Dashboard → Payments.
Do you keep my slip pictures?
No. The picture is read inside your browser. For members only the transaction reference is kept, to warn about re-used slips.
Why does it say no QR was found?
The picture may be cropped, blurry or photographed from a screen. Ask for the original slip. A slip without any QR is a warning sign.
Does a green result mean I got paid?
It means the slip looks genuine and is new. Always confirm the money in your bank app before handing over goods.
