Bakong: the rail under every deposit you make

Bakong is a rail, not another app to install

Ask someone in Phnom Penh how they paid for something and they will name an app: ABA, ACLEDA, Wing, TrueMoney. Ask what happened underneath and the answer is almost always បាគង, the rail carrying it. Bakong is a mobile payment and banking system initiated and operated by the National Bank of Cambodia, and it has run as a consumer app since 2020. It gathers e-wallets, mobile payments, online banking and financial applications into one interface, and it moves money three ways: by scanning a QR code, by keying in a phone number, or by picking a name out of a contact list. Sixty-three institutions are official members with seven more mid-integration — ABA Bank, ACLEDA, Wing Bank, Canadia and Sathapana among them, on the same list as e-money operators including TrueMoney Cambodia, eMoney, Pi Pay, Ly Hour Pay Pro, BongLoy and U-Pay Digital. That mixed list is the point: bank accounts and wallet accounts are interoperable on one rail, which is why money out of a wallet lands in a bank account without anybody thinking about it.

One correction is worth making early because it circulates constantly: Bakong is not a central bank digital currency. Around 80% of the payments crossing it are in US dollars, and the balances behind them are commercial-bank money rather than central-bank liabilities — a tokenised deposit and settlement platform is the accurate description. That distinction is not academic for anyone funding an account. The money in your app is your bank's money, your bank's limits apply to it, and your bank's fee table is the one to read before you press send.

The wallet and the rail are two different products

Most of the confusion on this subject comes from one name covering two things. There is the Bakong rail, which your ABA, ACLEDA or Wing app rides on whenever you send money to another institution. And there is the Bakong wallet, the National Bank's own app account, held directly rather than through a commercial bank. They do not behave the same way, and the gap between them is a hard number: the Bakong wallet has a balance ceiling of 10,000,000 riel or 2,500 US dollars. A bank account on the rail has no equivalent ceiling.

That ceiling cascades downstream. Topping a Bakong wallet up from an ABA account is capped at 4,000,000 riel or 1,000 dollars in a single transaction, 10,000,000 riel or 2,500 dollars in a day, and 80,000,000 riel or 20,000 dollars in a month. Send from an ACLEDA Bakong account instead and you get 2,500 dollars a transaction and 10,000 a day, free of charge. Send bank-to-bank across the rail and the room is a different order of magnitude: an ABA customer can move up to 240,000,000 riel or 60,000 dollars per transaction and per day to other members. The practical reading is short — use the bank account, not the wallet.

The rule that decides whether your transfer lands

We run Cambodian balances in US dollars, and we would rather say so above the instructions than underneath them. Our platform carries two internal codes for this market, KHUSD and KHEUR, both labelled Cambodia, resolving to dollars and euros, and our registration configuration restricts the Cambodia region to a single currency: USD. There is no riel balance in that configuration at all — no KHR account waiting to be opened, and no quiet conversion hiding inside the cashier. Now put that beside the rail's own constraint, which is just as absolute: Bakong does not do cross-currency. The currency of the transfer and the currency of the receiving account must match, with no in-app FX anywhere in the chain.

Sending a Bakong transfer into your BK8 account

Do the whole thing in one sitting with the phone in your hand. The sequence below is written around ABA Mobile because it is the app most Cambodians already have open, but the shape is identical from ACLEDA or Wing — source account, destination, currency, confirm. The only screen worth slowing down on is the currency selector. Three bank codes are configured on our side for Cambodian deposits: ABA, ACLEDA and Maybank. Our ABA Pay walkthrough covers that app screen by screen.

1. Check which side of the app the money is on. Riel and dollars are separate balances and nothing on this rail will bridge them for you.
2. Finish verification first. A Cambodian account with us needs a mobile number under the 855 country code and an email address, both confirmed — no birthdate or bank check at that stage.
3. Decide the amount before you start, not during. The welcome match is measured against the first deposit that lands, and there is only ever one first deposit.
4. In ABA Mobile the path is Transfers, then Transfer to Local Bank - Bakong, then your source ABA account, then the recipient bank and account number.
5. Choose KHR or USD, then enter the amount. If that selector does not read USD, stop and fix it rather than sending and hoping.
6. Confirm with your ABA Mobile PIN. That screen is the last one; there is nothing after it to approve.
7. Watch for the confirmation in your own bank app, then check the cashier. Once it posts, claim the offer: +1500% on that first deposit and 250 free spins on slots.

What it costs, and who is actually charging you

Fees here are small, banded and published — but no single institution publishes all of them, which is why people assume they are hidden. The National Bank sets the rail and does not cap how many transfers you make in a day; each member sets its own amounts and its own pricing on top. So the question is never what Bakong charges. It is what your bank charges to put money on Bakong.

A pattern falls out of that table. Money coming out of a Bakong account is generally free; money pushed into one costs a few cents above a threshold. None of these figures changes a decision — the largest charge on the list is a dollar fifty — but they explain why a 500-dollar transfer sometimes shows a fifty-cent line and a 40-dollar one does not.

Who can register for Bakong, and what visitors do instead

Registration is deliberately light — the rail exists because the National Bank wanted to bring the roughly 70% of the population outside the banking system into it — but it is not open to every person or every account. You need a National ID card or a passport plus a local valid phone number, and the account you attach has to be an individual savings or current account. Joint accounts and fixed-deposit accounts cannot register, which surprises couples who share a book at the branch. Visitors go through a separate door called Bakong Tourists.

• Residents: a National ID card or passport, a local phone number, and an individual savings or current account. Joint and fixed-deposit accounts are excluded.
• Visitors: Bakong Tourists registers by email and one-time code, personal details, a username, a password and a recovery QR code you must save somewhere safe.
• Verifying a tourist profile is a separate step — passport photo plus a selfie — and it is what unlocks a linked Visa or Mastercard and a higher daily limit.
• Once verified, a tourist can cash in at any Wing Bank branch, pay by KHQR at merchants, and cash out at a Wing branch or agent.
• On our side: a phone number under country code 855 and an email address, with Sumsub handling identity checks for both Cambodian currency codes.

KHQR is the other half of this story and usually the half people see. It is the single national QR standard, launched in early July 2022 with all 37 Bakong participants supporting it on day one, replacing roughly fifty incompatible bank QR codes at checkout. Scan one and the payment routes through Bakong underneath, whichever bank app you used. The KHQR page covers the code itself.

Getting cash into Bakong, and out of it, without a card

Cambodia solved the cash problem with people rather than machines, and the agent networks are the most useful thing about this rail. Wing publishes free cash-out at more than 12,000 agents nationwide with no fee and no minimum — its own description of the range is from 2,000 riels to millions. Open the Wing Bank App, tap QR Scan, scan the code at any agent displaying the Bakong Cash-Out sign, take the money. TrueMoney runs the same idea from the other side. Its agents handle cash-in and cash-out for accounts at more than 60 Bakong member institutions — not only TrueMoney wallets — by scanning the KHQR code in your app, across 10,000 locations, in riel or dollars, with a push notification and a paper receipt. The Wing route is written up here.

Physical cash into a Bakong wallet is narrower than people expect. At ABA it happens in exactly one building — the Head Office Operational Hall on Preah Sihanouk Boulevard — where cash-in runs 2,000 to 6,000 riel or 50 cents to 1.50 dollars by band and cash-out is a flat 2,000 riel or 50 cents. Set any of that against an ATM and the agent network wins on every axis: Cambodian ATM operator fees run roughly 4 to 10 dollars a withdrawal, with Vattanac at the low end and ABA commonly cited at 6 to 10, a standard 500-dollar per-transaction limit, and machines that hand you fifties and hundreds whether you wanted them or not.

Riel, dollars, and taking the money back out

None of the currency discipline above is us being awkward — it is how the country already banks. At the end of 2025, 83.4% of broad money in Cambodia was denominated in US dollars. Everyone here lives with two currencies at once and works from the 4,000-riel convention, with riel handed back as change for anything under a dollar, while the market rate sits slightly above it: ACLEDA's board on 10 September 2026 read 4,048 riel buy and 4,062 sell. That riel became sub-dollar change is structural rather than cultural. From June 2020 the National Bank moved to phase 1, 2 and 5 dollar notes out of domestic circulation, having banks collect them and ship them abroad; small notes were never banned, banks simply stopped handing them out.

Money leaves the way it came. A withdrawal is the same rail run backwards — dollars out to a dollar destination, no conversion in the middle — and any Wing or TrueMoney agent counter turns it into notes without a card. Our withdrawals page covers what we ask for before the first payout clears. If Bakong is not the door you want today, the others open onto the same cashier.

One last thing, and it matters more than any fee band above. A Bakong transfer asks for nothing but a PIN, which is exactly the quality that deserves a limit attached to it. Set a deposit cap and a session length while the account is still empty; it is a five-minute job then and a much harder conversation later. The tools sit here, and setting them costs nothing but the five minutes. When you are ready, open the cashier — the first deposit carries +1500% and 250 free spins, and it is the balance that first transfer lands on that the match is measured against.
