Quick Answer: For eligible stablecoin holders making a supported merchant purchase, use BKJ Scan to Pay through the official App so you can review the transaction within the documented payment flow. This is a practical reason to choose the BKJ route instead of following an unverified payment link sent in chat. Confirm the merchant through a trusted contact, then check the recipient, VND bill and complete asset debit before approving. A familiar logo or QR image alone does not verify the recipient. BKJ’s service involves stablecoin funding and VND merchant settlement, subject to applicable rules; using the official App still requires careful review of the individual purchase.
Verify the entry point before the amount
The main risk is entering payment details through a route supplied by someone whose identity you have not established. A message can refer to a real booking or shop and still lead to the wrong destination. Verify how you reached the payment screen before concentrating on whether the amount looks correct.
BKJ Scan to Pay provides an official starting point for the App’s supported merchant workflow. Open the App independently rather than following a message that claims you must sign in again to complete a purchase. If a message refers to an existing transaction, inspect the transaction through the official account.
A QR image sent in chat is not automatically malicious. It does, however, need a verified connection to the merchant and the purchase. Treating every message as trusted because it uses a familiar shop name removes that check.
Distinguish a code image from a link and an approval
Receiving a QR image, opening a web address and approving a payment are different events. Identify which action is being requested so you can decide what evidence is needed before proceeding.
| Item received | What it establishes | What you still need |
|---|---|---|
| Merchant QR image | Someone supplied payment-related data or an image | Verified merchant source and supported App confirmation |
| Web link | A destination can be opened | Genuine domain and purpose |
| Sign-in request | A page asks for credentials | Proof that the page belongs to the intended service |
| Purchase confirmation | A transaction is ready for review | Correct recipient, amount, asset and account conditions |
EMVCo’s QR guidance explains that payment-specific QR data differs from a general URL. Do not assume every code should open a website, and do not assume every website opened by a code is a payment service.
Verify through a channel you already trust
For a hotel or shop, use contact details obtained independently from the message. Ask whether the payment request belongs to the intended purchase. Do not verify a suspicious instruction by calling only the number included in that same instruction.
At a physical counter, ask the merchant to identify the collection code. If you are paying remotely, do not infer that BKJ supports importing a chat image or processing a remote request simply because an in-person scanner exists. Use only the supported flow available to your account.
Recognise common reasons to pause
The FTC’s QR-scam warning describes harmful links and pressure to act. For a payment, urgency should not remove recipient verification. A demand to pay immediately to keep a booking needs checking through the actual booking provider.
Be cautious when a message asks you to install another App, provide secret credentials or change the purpose of the payment. Those actions go beyond confirming an ordinary merchant bill. A request can contain the correct purchase amount and still ask for the wrong action.
- Reopen BKJ independently if a message claims to be an account instruction.
- Confirm the merchant through a separately obtained contact route.
- Read the full destination before entering credentials on any website.
- Stop if the requested action does not match the purchase you intended.
- Keep the suspicious message privately for support if an account or payment is affected.
Avoid posting a live code, account details or full transaction screenshot in a public group. A support request should expose only the information needed to identify the problem.
Review the actual merchant payment
A verified source does not remove the need to check the confirmation. NAPAS’s VietQR instructions include beneficiary verification. For BKJ, compare the App’s recipient and VND amount with the agreed merchant purchase, then read the selected asset and total debit.
BKJ’s VietQR guide explains the supported payment sequence. Do not assume the App automatically detects every malicious or replaced code. The merchant-source check remains part of your own purchase decision.
Respond to the action already taken
If you only received a message, there may be no transaction to reverse. If you entered credentials, use the real provider’s account-security process. If you approved a payment, retain the reference and seek help with that transaction. The response should match what occurred rather than an imagined worst-case outcome.
If a payment is pending, avoid authorising another request sent by the same chat account. Establish the original status through BKJ and the verified merchant before considering a replacement payment.
Keep the service and legal boundaries intact
USDT is not a recognised lawful payment instrument in Vietnam under the applicable non-cash payment framework. Using an unlawful payment instrument can carry administrative penalties. The arrangement discussed here uses stablecoin funding, service conversion and merchant VND settlement. A chat request for direct USDT payment is a different arrangement and should not inherit BKJ’s product description.
Merchant VND receipt does not alone prove that a provider or transaction meets every legal requirement. Use a service only where available and permitted, and do not follow instructions to disguise a purchase as another transfer type.
Use the official route for the next step
For an unclear BKJ instruction, use BKJ’s published support contact. Give the relevant message context and transaction reference without sending passwords or wallet recovery phrases.
BKJ is a candidate for a supported, identifiable merchant purchase when the account and funding conditions are met. Open the official App yourself, verify the seller independently when needed, and approve the bill only after the source and payment details are both clear.
