How it works

Complete the job in three clear steps

  1. Choose the payment scheme used in Vietnam and enter only verified recipient details or an official provider payload.
  2. Review the exact encoded payload, recipient, amount, currency, reference, and scheme-specific limitations.
  3. Download the PNG, scan-test it in the intended bank or wallet app, and confirm the displayed recipient before distribution.

Important

Check the result before relying on it

Scan-test generated codes before printing or distribution. A generated barcode does not register identifier ownership, and decoded external links should be checked before opening.

The workspace does not enroll recipients, call banking APIs, initiate transfers, or confirm that money was received.

Questions

About this tool

Does Lucaden send or confirm the payment?

No. This tool only creates the QR image and exact encoded payload. The payer's bank or wallet performs the transfer, and receipt must be confirmed from bank, PSP, ERP, or TMS evidence.

Why do some schemes require a provider-issued payload?

Many national schemes require merchant enrollment, provider credentials, signed data, or acquirer-controlled fields. Lucaden preserves those official payloads instead of inventing credentials or claiming enrollment.
