Saved Payment Methods & BDX Wallet Integration

The Saved Payment Methods & BDX Wallet System provides Bangladeshi buyers with a fast, frictionless checkout experience. Built specifically for local financial channels—including Mobile Financial Services (bKash, Nagad, Rocket), local debit/credit cards, and BDX’s instant internal ledger (BDX Wallet)—the payment infrastructure minimizes checkout steps while maintaining strict security and buyer protection.

This document details saved payment methods, wallet balance usage, 1-tap checkout workflows, and account security protocols on BDX.market.

1. Supported Payment Channels​

BDX.market supports Bangladesh's dominant payment channels, ensuring every gamer across the country can complete transactions using their preferred financial method:

  1. Mobile Financial Services (MFS): bKash, Nagad, and Rocket account integration for direct manual proof submission or automated gateway settlement.
  2. Cards & Electronic Payments: Local bank card processing supporting VISA, Mastercard, UnionPay, and DBBL Nexus cards.
  3. BDX Wallet Balance: Instant 1-tap internal balance settlement funded via refunds, earnings, or direct top-ups.

2. Security & Payment Data Protection​

To protect buyer financial data, BDX.market never stores raw credit card numbers, CVVs, or MFS PIN numbers on its servers:

  • Tokenized Credentials: Financial accounts use secure payment tokens provided by payment partners.
  • Masked Display: Account identifiers display in masked formats (e.g. 017****8819 or Visa ending in 4920) for recognition without exposing sensitive details.

3. BDX Buyer Wallet Integration​

The BDX Wallet is an internal balance system that provides zero-fee, instantaneous payment settlement for buyers:

  • Instant Dispute Refund Credit: When a dispute resolves in favor of a buyer, funds credit to your BDX Wallet balance immediately, bypassing multi-day bank processing delays.
  • Pre-Funded Top-Ups: Buyers can top up their BDX Wallet balance via bKash/Nagad in advance, enabling 1-click purchases for flash sales and limited game key drops.
  • Zero Processing Fees: Transactions paid using BDX Wallet balance bypass third-party payment gateway surcharges.

4. 1-Tap Quick Checkout Experience​

Saved payment methods enable a frictionless 1-Tap Checkout experience:

  • Select your preferred saved payment method or BDX Wallet balance at checkout.
  • Click Pay & Unlock to complete your order instantly.

Security Re-Authentication Safeguards​

Even with saved payment methods, 1-tap checkout enforces secondary verification under specific conditions:

  • High-Value Orders: Large checkout totals require dynamic OTP verification.
  • New Device or IP: Initiating a transaction from an unrecognized browser or location triggers a security verification prompt.

5. Managing Saved Payment Methods​

Buyers retain full control over saved financial details:

  • Default Payment Choice: Toggle your default payment method anytime under Account Settings.
  • Instant Revocation: Remove saved payment options with a single click.
  • Data Cleanup: Removing a saved method permanently unlinks payment tokens from your account profile.
