Quick answer
Sometimes, but not by default. Passport acceptance, phone-number eligibility, card linking and wallet funding are separate checks. Confirm each one in the official onboarding flow before transferring money.
1. Separate identity from funding
An app may verify a foreign passport yet still require a supported local phone number or bank account. It may accept a card for one purpose but not allow that card to top up a wallet balance. Treat each requirement as independent.
Use the exact country of card issuance and residence when checking eligibility. Rules for a UK-issued card may not apply to a card issued in Japan, Australia or another market.
2. Registration checklist
| Question | Evidence to find |
|---|---|
| Is my passport accepted? | Official verification page or in-app flow |
| Is my phone number accepted? | Country-code selector and OTP test |
| Can my card fund the wallet? | Named funding method and issuer-country rules |
| What are the fees and limits? | Confirmation screen and current fee page |
| How do refunds work? | Official support or product rules |
3. Safer funding steps
- Install only from the official store or website.
- Complete verification before moving a large amount.
- Make one low-value funding test.
- Check the wallet balance and transaction record.
- Keep a card and some cash available.
Where BKJ QR Payment fits
BKJ QR Payment is most relevant when you already hold USDT or USDC and the merchant displays a code recognised by the BKJ App. A verified user scans inside the official App, checks or enters the VND amount, selects the stablecoin, reviews the displayed fee and final debit, and approves. The merchant remains in the local fiat payment flow rather than accepting stablecoins directly.
BKJ lists a 1% QR payment fee, but the confirmation screen is the final place to check the amount and fee. Registration, identity verification, sufficient balance, service availability and a supported code are still required. Keep a card or some VND as an independent backup.
Final recommendation
Do not rely on a payment app because it appears in an app store or accepts your passport. Rely on it only after the complete identity, funding and merchant-payment path works for your account.
