MothCard is a virtual payment card funded from a crypto balance, built for people who cannot get an ordinary bank card to work online. The card settles in US dollars, is issued on Visa or Mastercard, and its stated centre of gravity is online payments rather than cash machines or physical shops. That is a narrow but real use case, and the product does it plainly enough.

What makes it hard to recommend without hesitation is not the design. It is the paperwork behind it. The company behind the app is Hong Kong Yunmo Technology Co., Limited in Tsim Sha Tsui, Hong Kong. The bank or institution that actually issues the card is not named on the public pages, no licences are named, the fee amounts are not published, and the daily and monthly limits are not published either. You find all of that inside the app, which is normal for this category and unhelpful if you want to decide before you sign up.

I scored it 5.4 out of 10. That is a middling mark, not a rejection, and it is not a statement that the card does not work. It reflects a product that does one job competently while leaving the questions a careful buyer asks unanswered in public.

Conditions are current as of October 28, 2026.

The score in full

Here is how the total breaks down, criterion by criterion, so you can see which parts are strong and which are thin.

Two of the six criteria score 6 because the card does what it is meant to do, which is spend online from a crypto balance. The other four sit at 5 for the same underlying reason: absence of published information. Not concealment, as far as I can see — just silence where most competitors publish something.

Who they will give the card to

The starting point is Hong Kong, per section 3.1 of the Terms of Service. From there the site says the card is “accepted worldwide” and immediately adds that “some countries or regions may have restrictions”. Those two sentences together are the honest summary of eligibility: broad in principle, gated in practice.

One detail worth pausing on is that the issuing region varies by card and is visible in the app. In practice that means you may apply, pass the identity check, and find that the card you selected was issued under a different region than you expected. Whether that matters depends on why you want the card. If your concern is a merchant refusing a payment, a Hong Kong-issued card may behave like any other foreign-issued card. More on that below in the section on paying with it every day.

There is no published country list, no statement about your nationality, and no statement about countries you are merely visiting. The site’s own wording — restrictions exist, region varies by card — is the whole of what is on offer before you install anything. If you are in a specific country and want to know before you sign in, the honest answer is that you cannot tell from the public pages, and you would have to look in the app.

One point of general background that bears directly on the “worldwide” claim, since it explains a mechanism rather than a MothCard rule. Every payment card number begins with an issuer identification number, six or eight digits, that identifies the issuing institution; the rest is an account identifier and a check digit. A merchant can look up those digits to see which institution and country issued the card, and some apply extra scrutiny when the issuer country differs from the billing address. That is why a card issued in one country can look foreign to a shop in another. When you read “accepted worldwide”, you are reading about acceptance at the network level. Whether a particular cashier waves it through is a different question, decided at the till.

How to get it

There is a one-time identity check, described by the card as being for AML and sanctions purposes. The material you need is “Just one valid personal ID”, with the accepted types shown in the app for your country. In some cases there is a face scan. Proof of address is not stated. The age requirement is not stated either, though the App Store listing carries an 18+ age rating.

The sequence itself is short, and this is where the product is at its most confident:

• Sign in to the app
• Choose your card
• Verify your identity
• Top up the wallet
• Move funds onto the card

That last step deserves a note, because it is the one that surprises people. Funding is not one action. You top up the wallet first, and then move money from the wallet to the card, and the card spends what is on the card. The card balance and the wallet balance are shown separately. If you deposit and immediately try to pay, the money is sitting one step short of where it needs to be.

What you get is a virtual card — the card describes itself as a “crypto virtual card for global payments” — issued on Visa or Mastercard, settling in USD. Physical delivery is not applicable, because there is no physical card. That is a genuine limitation rather than a missing feature: if your plan involves handing a card to a waiter or sliding it into a terminal that takes plastic, this is not that.

There is nothing on the public pages about tiered verification levels or higher limits for higher-sourced customers. Nor is there any mention of what happens if the identity check fails. In this category a failed check is usually a refusal with no appeal described in advance, so treat the first attempt as the one that counts.

What it really costs: Fees, limits and the price of a coffee

The fee picture is the weakest part of the file, so let me be blunt about it before the details. The card’s own pages say there are fees for issuing and maintaining a card. The amounts are shown in the app only and are not published. Per-operation fees are not stated. Cash machine fees are not stated. The limits are not published. Nothing here is hidden behind a login wall that a competitor would have opened; it simply is not on the public pages.

Three everyday payments, and what you actually know about each:

A subscription in dollars. You pay USD, the card settles in USD, and if your crypto balance is USDT there is no currency conversion in the middle. This is the cleanest case, and it is the one the card is built for. What you still do not know is whether there is a per-payment fee on top of the network cost.

A purchase priced in euros or pounds. Here you cross into the two numbers the card does not publish: the conversion rate and the FX fee. You are converting from a dollar-pegged balance into another currency at a moment when the crypto market is moving, and the spread applied to that conversion is the part that determines what the purchase actually cost. The card does not publish the spread, so I cannot tell you what it is, and I would not guess.

A purchase funded from a non-USDT holding. To pay from, say, BTC or ETH, the balance has to be converted first, and then the card spends the fiat result. The cost is the on-chain network fee for the transfer or swap — charged by the blockchain, not by the card provider — plus whatever conversion spread applies, plus any operation fee the card may charge. The published material does not let me total this for you.

One more general fact that belongs in a costs discussion, because it is the fee people forget: on-chain network fees for your deposit are charged by the blockchain itself, not by the card provider. So when you top up, the amount that lands in your wallet is not the amount you sent. On some networks this is negligible; on others it is not.

Nothing is published about tiers or a monthly-fee waiver, but several cards are selectable in the app with differing issuing regions, so what you pay may depend on which one you pick. And because settlement is in USD with the wallet and card balances shown separately, you end up with two numbers to watch rather than one.

How to top it up

Top up the wallet with USDT, per the App Store listing. Other coins and networks are described as those “you used the network shown in the App” — a list that is not published. Depositing by choosing a network rather than by being told which one is correct is the single biggest practical trap in this product, and I would rather say so plainly than pretend it is a minor detail.

The order of operations is the same as at signup: top up the wallet, then move funds to the card. A deposit fee and minimum are not stated.

On the network question, some general background that will save you money if you read it before your first transfer. Blockchain transfers are irreversible. A deposit sent on a network the provider does not support, or sent to an address belonging to a different network, can be lost or need manual support recovery with no guarantee. So the network you choose is not a technicality — it decides whether the money arrives. Read it out of the app and match it exactly.

If you hold USDC rather than USDT, note that the two major dollar tokens are not always interchangeable across networks. Circle stopped supporting USDC on Tron in February 2024, so “USDC over TRC20” is not a native option. Tether’s USDT, by contrast, has been issued on networks including Ethereum, Tron, Solana, Polygon and Avalanche. And a network with its own fee mechanics can trap you in a different way: on Ethereum, fees are paid only in ETH, so a wallet holding USDT with no ETH cannot send at all. Tron prices fees through bandwidth and energy, often burning TRX.

One more thing to understand before you fund it, because it is not specific to any one card: stablecoins can lose their peg. TerraUSD collapsed in May 2022, and USDC temporarily lost its peg in March 2023 during the US banking crisis. A dollar-pegged balance is a reasonable expectation, not a guarantee.

Paying with it every day

The everyday case is Apple Pay and Google Pay, both supported. Which wallet goes with which card is shown in the app. Blocked merchant categories are not stated anywhere public, and that is worth noticing — because in this category blocks are routine. A merchant category code is a four-digit number classifying a business, and MCC 7995 covers gambling; many issuers block it on specific cards by policy rather than by law, and the blocked list varies by issuer. If gambling or another category matters to you, you will not find out from the site.

Using the card through a phone wallet is also the safer path technically. Apple Pay replaces the card number with a device-specific number stored in the Secure Element, never on Apple’s servers, and each payment carries a one-time dynamic code. The issuer can still restrict a tokenised number — blocking it on magnetic stripe, phone or web use — so this is not a guarantee that every payment will go through.

Other things that routinely go wrong with a card like this, and what is or is not stated:

• Declines on foreign-issued cards. Address verification compares the numeric parts of the billing address the buyer typed against issuer records, and it is mainly offered in the US, Canada and the UK. It is generally unavailable for foreign-issued cards, which can cause declines. Some merchants also decline prepaid or foreign card numbers because the lookup reveals the card type and issuer country. If a payment of yours fails at a well-known merchant, this is the first thing to consider, and it has nothing to do with your balance.
• Authorisation holds. A declined authorisation can leave a hold on the funds that stays for several days, typically up to seven. A card with a modest balance and a large attempted purchase can be stuck.
• 3-D Secure. Online payments can be challenged with a one-time code or biometric. Visa’s brand is Visa Secure, Mastercard’s is Identity Check. Under 3-D Secure, liability for fraudulent online payments can shift, and the direction of that shift is contested.
• Refunds and disputes. The app history lists payments, fees and merchant refunds, which is a useful record. The dispute and chargeback process itself is not stated. A chargeback is a refund ordered by the issuer to settle a dispute, with reason codes such as fraud, duplicate billing or goods not received — and prepaid-card coverage varies and should not be assumed. If a dispute matters to you, ask before you rely on this card for large purchases.
• Cashback and rewards. These are not stated on the card’s public pages. If rewards are the reason you are considering a card, this is not the right choice.

The app is on iOS from 15.6, on Google Play, and as a direct Android APK. It is rated 5.0 on the App Store — from a single rating, read on 2026-10-21, so treat that number as an absence of data rather than a verdict. The Google Play rating was not obtained. The version history shows a first release of 1.0.0 on February 3, with no year shown in the listing, and version 2.1.0 as the recent one. A product that has shipped for some time and is still not much talked about is itself a data point.

What can go wrong

I looked for trouble and mostly found nothing, which cuts both ways. Searching for reviews across the major complaint and discussion sites returned nothing about MothCard, and no Trustpilot or Reddit page was found in a search of 2026-10-21. No official incidents came up either. But a product with one App Store rating and no review footprint does not have a reputation — good or bad. Silence is not a clean record.

The company is Hong Kong Yunmo Technology Co., Limited, Tsim Sha Tsui, Hong Kong. That is a real, named entity, which is more than many cards in this category offer. What is not named anywhere public is the issuing bank or institution, and no licences are named. Here is why that matters more than it sounds. When you hold a card, three parties are involved: the card network routes messages and sets the rules, the issuer is the bank or e-money institution licensed to issue under that network’s licence, and the crypto brand is often only a programme manager or front end. If you do not know which of those MothCard is, you do not know who holds your balance or who answers you when it is wrong.

There is a good example of what a programme ending looks like. In November 2022 Visa said it had “terminated our global agreements with FTX”, and the FTX US debit card programme was wound down by its issuer. Separately, WaveCrest, a Visa issuer that supplied crypto card brands, was suspended by Visa in Europe in 2018, closing all WaveCrest-issued Visa programmes. Closures tend to follow a pattern: a notice period, then spending and loading stop, then users are asked to withdraw what remains. One 2026 closure reported by a secondary source ended new loads on 8 July 2026 and spending on 8 August 2026 — single source, unconfirmed, and included here only to show the shape of the risk rather than to predict anything for this card.

Note also that Visa and Mastercard do not issue crypto cards to consumers themselves. They license issuers, and they can suspend a programme. So the card existing today says little about the card existing in three years.

The custody model is not stated. This is the single most important unstated thing on the page, so let me be explicit about the choice you are making. Control of crypto belongs to whoever holds the private key. With a custodial wallet, the provider holds the credentials and you must trust them completely. A seed phrase, typically 12 to 24 words, is an unencrypted form of that key — anyone who obtains it can restore the wallet and spend the funds. Transfers are typically irreversible, and a stolen key has no built-in recovery: the network cannot freeze or return the money. The historical record of custodial platforms is not encouraging — about US$350 million reported stolen from Mt. Gox between 2011 and 2014, about US$400 million from Coincheck in 2018, and US$625 million from the Ronin Network in 2022. With a self-custody-linked card the funds stay in your own wallet until the moment of payment, but then key loss, phishing and clipboard-hijacking malware become your problem alone. Neither answer is free; one of them is just an unstated choice.

On the practical side, the app does the right things in the right places: card freeze and unfreeze inside the app, and the full card number and CVV viewable after an identity confirmation and then hidden again. Sign-in is by email, Apple or Google, with optional Face ID or fingerprint. Those are the safeguards you would expect — app-based two-factor, instant freeze, spending limits — and their presence is a point in the card’s favour.

What is not stated is the support side. Contact Support inside the app, a Telegram bot, and the email address [email protected] are given; hours are not stated. The site has a language menu with 12 languages, and the App Store listing is in English, Indonesian, Portuguese, Russian, Simplified Chinese, Spanish and Traditional Chinese. Multilingual support matters here for a practical reason: sanctions screening is applied to citizenship and country of birth as well as to the country of address, and if an automated check flags you, the quality of the person on the other end decides how fast you get an answer.

On withdrawals, the material is thin and the advice is worth following anyway. The public pages do not explicitly cover withdrawing from the card; the FAQ advises moving any remaining balance off a card before cancelling it, and funds out of both card and wallet before deleting the account. Fees are not stated. Follow that sequence. If you have ever been told to move money somewhere quickly, that is the pattern a scam uses, and the advice here is the opposite of it.

Regulatory context, briefly, since it explains what a licence would have meant. Under MiCA, the EU’s markets-in-crypto regulation, e-money tokens may be issued only by a credit institution or an electronic money institution. EMIs must safeguard customer funds by segregating them or insuring them, but those funds are not the same as bank deposits and may not sit under a deposit guarantee scheme. ESMA also keeps an interim register of authorised providers, which is a place to check a name. A card, though, is regulated separately from the crypto side — which is exactly why a crypto card often depends on two licences, and why one unnamed issuer leaves a gap.

Finally, taxes, and I will not give advice here, only the mechanic. Digital assets are generally treated as property, so exchanging them for goods, services or dollars produces a taxable gain or loss. For personal or investment holdings that result is a capital gain or loss, short-term if held a year or less, measured in local currency at the fair market value on the transaction date. Each card payment funded from crypto may therefore be a separate disposal. Talk to an accountant in your own jurisdiction before this becomes a large habit.

What to take instead

None of these is dramatically better — my marks for them are 4.7 to 5.6, and MothCard’s 5.4 sits inside that band. The point of the comparison is to show what more disclosure looks like, not to crown a winner.

Read across the rows and the pattern is clear. MothCard is the one that tells you its fee structure exists and refuses to say what it is. CardFlow is the one that names a free action. Cardex is the one that makes a marketing claim about its conversion rate without publishing a percentage — a claim I would treat as unconfirmed until a rate is visible in your own transaction. And all four say “not stated” for rewards, which tells you something about how this category competes.

Two filters matter more than the scores. First, focus. Cardex’s listing is Naira-focused and CardFlow is built for Nigeria; MothCard and HyperCard are the more broadly aimed of the four. Second, the three things that are worth insisting on from any of them, because none of the four publishes them: who issues the card, what the limits are, and what it costs to convert. Ask, and see how quickly you get a straight answer.

Who I would recommend it to

I would recommend MothCard to someone in a specific situation: you need a card number that works at online merchants, you already hold USDT or can get it easily, you are spending small amounts regularly, and you can live with opening the app to read the fee and limit figures before you commit to something. If that is you, the card does its job, and the app’s flow — sign in, choose, verify, top up, move — is genuinely simple.

I would not recommend it as your main card, and I would not recommend it to anyone planning meaningful spend. The reason is not the 5.4. It is that four things you would need before spending real money are absent from the public pages: who issues the card, what the fees are, what the limits are, and how a dispute is handled. You can find all four in the app, and a determined reader could find them in an afternoon. But a card you have to install and fund in order to evaluate is not a card you can evaluate against its competitors.

There is also a specific group I would point elsewhere. If your problem is that a merchant declined your bank card, a crypto-funded card issued in Hong Kong may simply replace one foreign-issued card with another, and address verification is generally unavailable for cards like this — which is a common cause of declines in the first place. If your problem is that you have no banking relationship at all, this card does not create one, and it does not give you a credit line, a deposit guarantee, or a phone number to call.

What would move my mark? Publishing the issuer, the fee schedule and the limits on the website would take three of the four criteria off the table and would put this in the upper half of the category. Until then, treat it as a narrow tool, use it for what it does, and keep the amount you leave on it small.

Frequently asked questions

What is MothCard?

MothCard is a virtual payment card that spends a balance funded from crypto. The card is issued on Visa or Mastercard, settles in US dollars, and the company behind it is Hong Kong Yunmo Technology Co., Limited in Tsim Sha Tsui, Hong Kong. It is aimed at online payments rather than physical shops or cash machines.

How does MothCard work?

You sign in to the app, choose a card, verify your identity once, top up the wallet, and then move funds from the wallet onto the card. The card spends only what is on the card, and the wallet and card balances are shown separately. So a deposit on its own is not spendable money until you complete that second step.

Is MothCard a bank?

Not on the published material. It is a card programme from a Hong Kong technology company, and the bank or institution that issues the card is not named anywhere public, nor are any licences. In a typical card arrangement the network sets the rules, a licensed issuer holds the programme, and the brand is the front end. Which role MothCard plays is not stated.

Is MothCard safe?

There is no obvious red flag, but there is very little to judge. No official incidents were found and no complaint or discussion pages exist, which for a card with one App Store rating means silence rather than a clean record. The app offers freeze and unfreeze, hidden card details after identity confirmation, and optional Face ID or fingerprint — sensible safeguards around an unstated custody model.

Does MothCard require KYC?

Yes, a one-time identity check for AML and sanctions purposes, described as needing “Just one valid personal ID”, with the accepted types shown in the app for your country and a face scan in some cases. Proof of address is not stated and neither is a minimum age, though the App Store listing is rated 18+. Signing in by email, Apple or Google.

What are MothCard’s fees?

The card states there are fees for issuing and maintaining it, but the amounts are shown in the app only and are not published. Sending money carries a service fee and a minimum, shown on the in-app confirmation page. Conversion, foreign exchange and cash machine fees are not stated. Any on-chain network fee for your deposit is charged by the blockchain, not by the card.

How do I top up MothCard?

Top up the wallet with USDT, per the App Store listing, then move funds to the card. Other coins and networks are shown in the app and the list is not published. Choose the network exactly as the app shows it: transfers are irreversible, so sending on the wrong network or to the wrong network’s address can mean the money is lost or needs manual recovery.

Can I use MothCard in my country?

That is genuinely not answered in public. The site says “Accepted worldwide” and also that “some countries or regions may have restrictions”, and the issuing region varies by card and shows in the app. Acceptance at the network level is not the same as eligibility for you, and merchants can decline foreign-issued or prepaid card numbers.

How do I add MothCard to Apple Wallet or Google Pay?

Both Apple Pay and Google Pay are supported, and the app tells you which wallet goes with which card. Using a phone wallet is the technically safer route, since the card number is replaced with a device-specific token and each payment uses a one-time code. The issuer can still restrict a tokenised number to particular channels and refuse a payment.

How do I withdraw money or close my account?

The public pages do not explicitly cover withdrawing from the card. The FAQ advises moving any remaining balance off the card before cancelling it, and funds out of both card and wallet before deleting the account. Fees are not stated. Whatever you do, take the money out first — closed card programmes stop spending and loading and then ask users to withdraw.
