How Crypto QR Payments Work: Scan → Pay → Auto Convert to Fiat

QR payments are popular because they’re fast, familiar, and work both in‑store and online. With MuseWallet, the core idea is simple: you scan a merchant’s QR code, pay with crypto, and the system automatically converts crypto to fiat for merchant payments. That means you can spend crypto in a “normal payment” flow, while merchants can settle in fiat.

  1. The 3-step flow (the whole mechanism in one view)

Here’s the complete flow exactly as you should think about it:

  1. Scan the merchant’s QR code
  2. Pay with crypto
  3. Payment successful: the system automatically converts crypto to fiat for merchant payments

If you remember only one thing, remember this: the QR code is just the “entry point.” The real value is that settlement can feel like fiat even when you pay with crypto.

  1. Two QR types you may see (and why they matter)

Not all QR codes behave the same. MuseWallet describes two types:

Type A — E‑wallet QR Code

You scan and pay with the MuseWallet app.

Type B — MuseWallet QR Code

You can scan via MuseWallet app, a browser, or even your camera, and then complete payment on a webpage.

This difference matters for troubleshooting: if your scan opens a webpage, you’re likely dealing with a MuseWallet QR code flow.

  1. Supported “spendable currencies” (and how to stay up-to-date)

MuseWallet lists the following spendable currencies on its QR Pay section:

  • THB
  • VND
  • IDR
  • PHP

More spending currencies may be added over time. For the latest list, always verify inside the app, since supported options can change.

  1. Real-world usage: in-store and online

MuseWallet positions QR Pay as available both in-store and online.

  • In-store: Scan the QR displayed at checkout, confirm the amount, and complete payment.
  • Online: You may scan a QR shown on-screen (for example, on a payment page) and complete payment through the app or a webpage flow.
  1. Common issues checklist (scan worked, but payment didn’t)

If scanning works but payment fails, it’s usually one of these categories:

  • Regional eligibility: Some countries/regions may be restricted or prohibited. Check Supported Regions before retrying.
  • Security and risk controls: Fraud monitoring or verification steps can trigger additional checks in certain situations (high-value, cross-border, frequent activity).
  • Currency availability: Spendable currencies and supported options can change—confirm the latest list inside the app.

If you’re troubleshooting, the fastest route is: confirm eligibility → confirm supported currencies → retry with a stable network connection and correct payment details.
