NADD Pay QR Payments on WhatsApp

Scan. Review. Authorize. Pay in NADD.

NADD Pay QR Payments brings QR-based payment requests directly into WhatsApp. Users can display a reusable personal QR, create a single-use NADD payment request, scan another user's QR, review the recipient and amount, and authorize the payment with their own PIN before funds can move.

Simple User Flow

From QR scan to authorized NADD payment.

NADD Pay turns a QR scan into a guided WhatsApp payment journey. The QR provides the payment reference; the user still controls the payment decision.

How to pay a NADD Pay QR

1. ScanScan the recipient's or approved business QR.
2. Open WhatsAppThe QR opens the official NADD Pay WhatsApp flow.
3. Send QR MessageSend the prepared QR message exactly as shown.
4. ReviewNADD Pay resolves the recipient and payment request.
5. ConfirmReview the amount, recipient and reference before continuing.
6. AuthorizeEnter your own PIN before the payment can execute.
Important:

A QR code is not a payment authorization. No NADD should move merely because a QR was scanned. The payer must review the payment details and enter their own PIN before execution.

QR Payment Types

Reusable identity and single-use payment requests.

NADD Pay supports different QR purposes while keeping the authorization step with the payer.

Personal QR

My QR

Creates or displays a reusable personal NADD Pay QR. The QR identifies the recipient but does not contain a fixed payment amount.

Reusable
Payment Request

Request NADD by QR

Creates a single-use payment request for a specified NADD amount. The request expires automatically and is intended for one completed payment.

Single Use
Credential Lifecycle

Reissue My QR

Revokes the current reusable personal QR and issues a new one, allowing users to replace an existing QR without changing their NADD Pay account.

Revocable
Business Acceptance

QR payment acceptance for approved businesses.

Approved NADD Pay businesses can use business QR payment flows designed to identify the business receiving account while preserving payer confirmation and PIN authorization.

Business QR flow

1

Display QR

The approved business displays its NADD Pay Business QR or creates a payment request for a specific amount.

2

Customer scans

The customer's phone opens the NADD Pay WhatsApp payment handoff.

3

Customer reviews

NADD Pay presents the business identity, amount where applicable, and payment reference.

4

Customer authorizes

The customer enters their own PIN. The business QR itself cannot authorize the payment.

No dedicated card terminal required

A NADD Pay QR can provide a simple acceptance interface for supported payments using a printed or displayed QR and WhatsApp-capable phones. The payment decision and authorization remain inside the payer's NADD Pay interaction.

Business QR availability is subject to approved business status, live NADD Pay controls, account status, applicable limits, and any compliance requirements in force at the time of payment.

WhatsApp Handoff

The QR code carries a secure payment reference into WhatsApp.

The QR does not expose the user's PIN or instruct the blockchain directly. It carries an opaque payment code that NADD Pay resolves on the server before presenting the payment flow.

What the user sees after scanning

Send to NADD Pay QR: <secure QR payment code> Please send this message as shown. Do not edit or delete the QR payment code.

The long code is a secure payment reference used by NADD Pay to identify the intended QR request. Users should send the message exactly as prepared.

What happens behind the scenes

  • NADD Pay validates the QR payment code.
  • The server resolves the intended recipient or approved business.
  • The payer sees the recipient and amount before authorization.
  • The payer enters their own PIN.
  • NADD Pay then processes the authorized payment through its supported payment infrastructure.
Security Architecture

QR identification is separated from payment authorization.

The design intentionally separates scanning, recipient identification, payment review and PIN authorization so that possession or scanning of a QR code alone is insufficient to move funds.

Opaque QR Code

The QR uses a secure payment reference rather than exposing a PIN, wallet credential or recovery phrase.

Server-Side Resolution

NADD Pay resolves the payment request within controlled backend infrastructure before presenting the payment flow.

Payer Review

The payer is shown the intended recipient and payment amount before being asked to authorize.

PIN Authorization

The payer's own PIN is required before the transaction can proceed to execution.

Revocation

A reusable personal QR can be revoked and replaced through the Reissue My QR function.

Single-Use Requests

Amount-specific QR payment requests are designed for one payment and include an expiry lifecycle.

Payment State Controls

The WhatsApp flow tracks payment stages such as amount entry, confirmation, PIN authorization, processing and completion.

User Control

Users can cancel or go back during the guided payment flow before authorization and execution.

Payment Infrastructure

A conversational QR payment layer for WhatsApp.

NADD Pay combines physical QR discovery with a conversational payment interface. WhatsApp is the interaction channel, while payment resolution, authorization controls and transaction processing remain within NADD Pay infrastructure.

Architecture

1

QR Payment Intent

The QR identifies a reusable recipient or an amount-specific payment request.

2

WhatsApp Interaction

The scan opens NADD Pay and transports the secure payment reference into the conversation.

3

NADD Pay Control Plane

The backend validates the code, resolves the recipient, manages the payment state and applies account controls.

4

Payer Authorization

The payer reviews the payment and enters their own PIN before execution.

Plain meaning

Users do not need to understand wallet IDs, blockchain addresses, QR payloads or payment protocol terminology. They scan, follow the WhatsApp instructions, check who they are paying, confirm the amount and enter their PIN.

This design is intended to make digital payment infrastructure understandable to everyday users while preserving explicit payment authorization.

Questions & Answers

Clear answers for users, businesses and partners.

These explanations are intentionally simple so that users do not need technical knowledge to understand NADD Pay QR Payments.

NADD is not legal tender, not a Central Bank Digital Currency, and is not issued, guaranteed, affiliated with or endorsed by the Bank of Namibia or the Namibian Government.

NADD Pay QR codes identify an intended recipient, approved business or payment request. A QR code does not authorize a transfer by itself. Users should verify the recipient and payment amount shown inside NADD Pay and enter their PIN only when they intend to authorize the transaction. Service availability, fees, limits, account controls and compliance requirements may apply.

NADD Pay representatives will never ask users to disclose a private key, recovery phrase, seed phrase or full wallet password. Users should access NADD Pay only through official channels.
