PromptPay with Krungsri
Krungsri, ธนาคารกรุงศรีอยุธยา, is the yellow one, formally the Bank of Ayudhya, and its app is KMA. PromptPay behaves exactly as it does elsewhere: one identifier registered once, payable from any Thai banking app.
Registering the identifier
A mobile number or a Thai national ID number is bound to one Krungsri account, in KMA, at an ATM or in a branch, once per identifier.
Look for the PromptPay entry in the app's services or settings rather than following an old guide: the names of menu items change with updates, while the requirement does not. Confirmation goes to the number being registered.
Your QR code in KMA
The app shows a code for your account, which covers the person standing in front of you. For a chat, a card, a counter or an invoice you want the code as an image you keep, which is possible because the payload is a national standard.
A code with your photo or your logo in the middle also stops the common mistake in a group chat, where three codes look identical and one of them is not yours.
Reading a Krungsri slip
Yellow branding, then amount, receiver with part of the name hidden, date and time to the second, and a reference number.
Read the receiver line as carefully as the amount. A genuine transfer to the wrong account produces a flawless slip, and that is the case that catches people who only check that the picture looks real.
Across banks and limits
Any Thai app can pay a Krungsri code and a Krungsri customer can pay any Thai code; the scheme does not care who banks where.
Your daily transfer limit is set per customer in the app. Checking it in advance is the difference between a deposit paid on time and an evening spent on the phone.
Using it with SlipDee
SlipDee builds the code from your registered identifier with your picture in the middle and keeps it in a labelled album.
The slips KMA produces are read in the gallery where they already are and filed against the bills they settle, which is how a split finishes without anybody chasing.

- Add your photo or logo to make it recognisable.
- Check your daily limit before a big transfer.
- File slips against what they paid for.

Open SlipDeeFrequently asked questions
Can I pay a Krungsri code from another bank?
- Yes. Every Thai banking app can pay every Thai PromptPay code.
Where is PromptPay in the KMA app?
- Under services or settings, with wording that shifts between versions. An ATM or a branch can also register it.
Can I move my number from Krungsri to another bank?
- Yes, by registering it there, which releases it here. An identifier has one destination at a time.
Does a Krungsri slip prove payment?
- No. Your own account does, and instantly.
Can I use the code for a small business?
- A personal code receives money, which is enough for a stall. With books to keep, a business identifier separates the two.
