If you have run into walls getting an ordinary bank card — a blocked application, a country the bank will not open an account for, a payroll account in dollars you cannot spend locally — then a card like ARQ is exactly the kind of thing you start looking at. ARQ is a virtual and physical Mastercard that spends from a balance of digital dollars held in an app, and it is open to residents of Mexico, Argentina, Colombia and Brazil. That is a narrow door, and if you are not standing inside one of those four countries, everything else on this page is academic.

I went through the card’s own pages and the public record around it. My score is 5.4 out of 10. That is not a scathing mark, and it is not a recommendation either. It reflects one genuinely excellent thing — everyday use, marked 9 out of 10 — sitting next to two thin areas: eligibility and top-ups, both marked 3 out of 10, and a transparency gap around the FX rate that I keep coming back to below.

The conditions described here are current as of October 28, 2026.

Who this suits: residents of Mexico, Argentina, Colombia and Brazil who already hold digital dollars, want a Mastercard for everyday spending and wallet payments, and are comfortable with a balance that is converted rather than a bank account with their own name on it. Who it does not suit: anyone outside those four countries, anyone who needs a card funded directly from crypto coins on a specific network, anyone planning ATM withdrawals from an Argentine-issued card abroad, and anyone who will not read the exchange rate in the app before every payment.

Will they give you the card?

Only in four countries. The country selector on the card’s pages lists Mexico, Argentina, Colombia and Brazil, and the physical card can be sent “anywhere within Argentina, Colombia, Mexico or Brazil” to a valid address in that country. So the eligibility test is not about your nationality, your profession or your income — it is about where you live and where you can receive post. A valid address in one of those four countries is the whole gate.

That is the honest answer to the search question “is ARQ card available in my country”, and it is worth being blunt about the consequence: if you are reading this from anywhere else, there is no reading around this. It is not a card with a long list of countries that varies by tier. It is four, and the shipping restriction matches the issuing list exactly.

One more thing belongs here, because it shapes who gets in and who does not. The card describes itself as a “secured credit card backed by the balance in your ARQ account”, with the balance held in USDc, the digital dollar. So this is not credit in the sense of a line you can exceed — the spend limit equals the USDc balance in the account, which is the safer of the two models. But “secured” is doing work in that sentence, and if you are someone who has had a credit card before, the word will read differently to you than the mechanics justify. There is no borrowing here. You can spend what you have loaded and not one dollar more.

How to get it

The route is short and it runs entirely through the app. Identity verification must be completed in the app — and the card cannot be created while that verification is pending or incomplete, which is the single most important practical fact in this section. Download the app, log in, then go to Home and the card banner and request either the free virtual card or the physical one.

What the app does not tell you is worth knowing in advance. The specific documents you will need, whether proof of address is required, and what the minimum age is: not stated on the public pages. Verification tiers are not stated either, nor are the reasons an application might be refused. What is stated is that account review can temporarily block card creation — so a rejection is not always a decision, and it can also be a pause.

On delivery, the scope again matches the four countries: Argentina, Colombia, Mexico, Brazil only. Time to arrival is given as 2 to 15 business days, and a separate article puts it at 7-10 business days, so treat the shorter figure as the more likely case and plan around the longer one. Shipping is $4.99 USD. What a replacement card costs is not stated, which is a small gap if you lose one abroad.

The virtual card is the sensible first step for anyone testing this, because it is free and instant to create, and it is the one you can push into Apple Pay or Google Pay. Order the plastic once you know the app works for you.

Fees: what it really costs

The headline cost story here is good, and it is good in a specific way: the card charges you for the plastic and for ATM withdrawals, and presents the conversion as a visible rate rather than a hidden spread. Here is what is actually disclosed.

The line that deserves your attention is the one about the buy and sell rates. What the card does not do is disclose a separate FX fee or spread. There is no number on the page telling you what fraction the rate costs you. The defence offered is that the rate is shown in the app before you confirm, which is real — but it means the cost of converting is entirely whatever the two rates are, and you only find out by looking. There is no second figure to compare it against. That is why cost still scores 8 and not 10.

Two or three everyday payments, and which fees actually touch them:

• The coffee. You tap with Apple Pay. There is no monthly fee, no annual fee and no disclosed FX fee, so what you pay is your balance minus the sell rate. If the coffee is priced in dollars and your balance is in dollars, this is the cheapest the card gets.
• The subscription in euros. Your USDc balance is converted at the sell rate, and the app shows that rate before you confirm. This is where the undisclosed spread lives — you are told the rate, not told what the rate costs you against the mid-market figure.
• The cash withdrawal. 1% of the amount, taken by ARQ, on top of whatever the ATM owner charges. With a Premium membership, up to 500 USDc per month of that commission is waived. Do not withdraw in Argentina on an Argentine-issued card: international ATMs are not permitted on it.

How to top it up

This is the weakest part of the product and the reason the top-up mark is 3 out of 10. You cannot load the card directly. The card cannot be topped up directly. What happens instead is that money goes to your ARQ account through the banking details in the app’s “Add” section, and the USDc/EURc balance that results is what backs the card.

So the flow is: bank transfer to your account, then the card spends from the balance that account holds. That is a perfectly normal model, and for someone paid into a local bank account it may be all you need. But for the reader who came here because their money is in crypto, it is the wrong shape. The specific coins and networks are not stated. The fees and minimums for the deposit are not stated either. What I can tell you is that the app converts incoming payments into USDc or EURc — so if you send dollars or euros, the account receives digital dollars or digital euros, and the card spends the digital dollar side.

Money also moves out, with the same asymmetry. Funds cannot be sent to other cards; they must go to a bank account. What that costs, and what happens to a remaining balance at closure, is not stated.

Two practical warnings, both of which come from how this category works rather than from anything ARQ did wrong. First, blockchain transfers are irreversible: a deposit sent on a network the provider does not support, or to an address belonging to a different network, can be lost or need manual support recovery with no guarantee. Second, because the card tells you nothing about supported coins or networks, you cannot protect yourself by checking first — that information is only available inside the app. Read the deposit details there before you send anything.

Paying with it every day

This is where the card earns its best score, and it earns it fairly. You get a virtual and a physical Mastercard. Apple Pay is supported, added from Home > Add to Apple Wallet; Google Pay is supported too, per the card overview. You can use ATMs worldwide with the physical card, subject to the Argentine exception above. The card balance sits in USDc, and payments in any currency are converted at the sell rate.

Between them, Apple Pay and Google Pay are what make this usable day to day. Once a virtual card is in a tokenised mobile wallet, the card number itself is replaced by a device-specific number stored in the phone’s Secure Element, and each payment carries a one-time dynamic code. In practice that means you tap rather than fish a plastic card out of a wallet, and you are not typing your card number into a website — though the issuer can still restrict the tokenised number for certain channels.

What is not stated: which merchant categories are blocked. That matters more than it sounds. A card issuer can block whole categories by policy rather than by law, and the blocked list differs from one issuer to the next. Gambling is the classic example — that merchant category is blocked on many cards by policy, and I cannot tell you from the public pages what ARQ does with it. If you spend anywhere unusual, check it in the app before you rely on it.

On rewards, there is nothing to claim. No reward program is described on the official card pages. The sign-up form says reward details are sent by email, which in practice means: do not count on cashback in your model of this card. Two tiers exist — the free Main Balance and Premium. Premium gives you a free first physical card and up to 500 USDc per month of ATM commission waived; what Premium costs is not stated, so you cannot weigh the benefit against a price from outside the app.

The app itself is the part you will look at most. On the App Store it is “ARQ: Global Finance” at 4.5/5 from 992 ratings, iPhone, iOS 17.0 or later. The Google Play rating was not obtained; the card’s own pages cite 4.7 and 4.5 app ratings without a date. The Help Center exists in Spanish, English and Portuguese, which is a genuine point in a four-country product.

What can go wrong

Start with the company, because it explains several of the rest. ARQ is the former DolarApp, under DolarApp Inc. In Colombia, virtual asset services are provided by DolarApp México S.A. de C.V. and credit card services by DAPP Colombia S.A.S. (NIT 901644165-9). A Mexico help page says credit card services are provided by Pier 5 S.A. de C.V. Licences are not stated. The rebrand from DolarApp to ARQ was reported by Brazilian press across 2025-2026. I found no licence events and no fines — but equally, the card’s public pages do not name the authorisations, and if you are being asked to hold funds through a company you cannot identify on paper, that is a fact to sit with rather than skip past.

Why this arrangement matters generally: Visa and Mastercard do not issue crypto cards themselves. They license issuers, and they can suspend a programme. The card network routes the payment and sets the rules; the issuer is the licensed institution holding the card programme; the crypto brand is often only the manager and front-end. That is why the entity names above matter — they tell you who is actually behind your balance and who you complain to when something goes wrong.

Now the complaints, which is why reliability is marked 4 out of 10. I found no official incidents. What I did find is user reports, and I am marking them clearly as such. Trustpilot’s ARQ page carries a single 1-star review dated 14 September 2026 about an unrecognised charge on a virtual card and no support solution. The ARQ Finance Trustpilot page reads 3.9/5 from 6 reviews. The older DolarApp Trustpilot page reads 2.0/5 from 128 reviews. Across those, and in app-store reviews, the recurring themes are an account frozen or blocked with funds held, an unauthorised charge, and slow support.

Read those numbers carefully rather than dramatically. Six reviews is almost nothing; 128 is a much louder sample, but it belongs to the previous name. What the pattern does suggest is that blocking an account while funds are held is a live risk, not a hypothetical one. Two rules follow. First, keep your balance sized to what you can afford to have temporarily inaccessible, because the card itself freezes instantly in the app — that is a feature, and it is also the mechanism by which your money stops being yours for a while. Second, the security model underneath is not stated: whether your balance is custodial, and whether client funds are safeguarded, does not appear on the public pages. That gap is normal for this category and it is still a gap.

On support: in-app chat runs 24/7, and complaints and claims have an address, [email protected]. The Help Center is in three languages. The route exists. The complaint pattern is about speed, not absence.

Finally, the slow path when money goes wrong. A Mastercard chargeback investigation can take up to 120 days, opening one does not guarantee a refund, and you track status in the Help Center or app with notifications and email. A declined payment can also leave a hold on your funds that stays for several days, typically up to seven. If a card is blocked from a category or a merchant declines it, the money may be unavailable to you long after the payment failed. Rights also differ by card type — in the US, debit card reversal rights come from Regulation E and credit card rights from Regulation Z, and prepaid-card coverage varies and should not be assumed. What applies to a secured card funded by a stablecoin balance is worth establishing in writing before you rely on it, and this page cannot establish it for you.

One last category risk, offered as background rather than as a prediction. Card programmes close. Programme closures typically give a notice period, then stop spending and loading, then ask users to withdraw remaining balances. It has happened: Visa terminated its global agreements with FTX on 13 November 2022 and the FTX US debit card was wound down by its issuer; WaveCrest, a Visa issuer that supplied crypto card brands, was suspended by Visa in Europe in 2018, closing all WaveCrest-issued programmes. I found no such event for ARQ. I am telling you the category risk exists because four issuing countries is a small footprint to be dependent on, not because anything specific is wrong here.

What to take instead

I cannot tell you which card is right for you — I do not know your country, your balance, or how you get money in. What I can do is put the alternatives next to this one so you can weigh them. All three below are scored on the same scale I used for ARQ.

The International Visa Card scores highest at 6.7, and it wins on two things ARQ cannot offer: a published 2% FX fee, so you know what conversion costs before you pay it, and a proper top-up line — deposit USDC or USDT into the USD account, free at 1:1, with networks not stated but the coins named. Against that, it is virtual only for now, the physical card is listed as “coming soon”, and its availability test is a long exclusion list covering Belarus, mainland China, North Korea, Cuba, India, Iraq, Iran, Israel, Myanmar, Nepal, Nicaragua, Russia, Syria, Turkey, Ukraine, Venezuela and Vietnam, with FATF grey-list countries reviewed case by case. The rule is by residence or registration; citizenship is not mentioned. Purchases are blocked in North Korea, Cuba, Iran, Russia, Syria, Ukraine and Venezuela. If you are in Mexico, Argentina, Colombia or Brazil, this is not obviously open to you — but if you are outside its exclusion list and want a card that publishes its FX fee, it deserves a look.

UNi Card at 6.1 is a multicurrency card on the Mastercard network that spends from a UNi.Global account balance, with no annual fee, no foreign transaction fee, conversion at live OTC rates and “no hidden exchange fees”, plus spend-to-earn rewards up to 3%. Its two silences are the two you would need answered first: who can get it is not stated, and how you fund it is not stated. A card that does not disclose its fees or its eligibility until you are inside the app is asking for the same trust I am asking you not to extend to ARQ’s FX rate.

Whop Cards at 5.2 are close to ARQ on score and differ in geography: US-state based rather than Latin American. Availability runs to 31 states for consumers and 41 for businesses, with a separate excluded-country list for consumers and for corporate customers. It is a Visa that works wherever Visa is accepted, spends from a Whop balance that becomes usable as soon as a payment arrives, and offers 5% cashback at select merchants, currently Uber. The costs line reads “No extra fees” with no amounts behind it, and the card type, currency and funding coins are not stated.

If you are in one of ARQ’s four countries and your money is already digital dollars, the comparison may not matter much — the others may not be open to you. If you are outside them, it matters a great deal, and the honest summary is that the alternative with the clearest published FX fee is also the one with the longest exclusion list, and the one with the best rewards does not publish its costs at all.

Who I would recommend it to

I would recommend ARQ to someone specific. You live in Mexico, Argentina, Colombia or Brazil. You already hold digital dollars, or you are paid into a bank account and want a dollars-denominated Mastercard without opening a second banking relationship. You want a virtual card in your phone’s wallet for everyday spending, and you are the kind of person who will open the app and read the sell rate before confirming a payment, because that rate is the price of the transaction and nobody else is going to tell you what it costs. You are willing to keep the balance small enough that a frozen account would be an inconvenience rather than a crisis. And you accept that the physical card goes to a local address, that ATM fees are 1%, and that an Argentine-issued card will not work at international ATMs.

I would not recommend it to someone who needs to fund the card from a specific coin on a specific chain — the coins and networks are not disclosed, so you cannot verify compatibility before sending. I would not recommend it to anyone planning to withdraw cash while travelling on an Argentine card. I would not recommend it to a reader planning to hold a large balance for months, because the custody and safeguarding position is not stated on the public pages and the complaint history is thin but consistent on accounts being blocked with funds held. And I would not recommend it as a way to keep money outside the banking system, because at its core this is a prepaid Mastercard: the spend limit equals your balance, the balance is USDc, and the convenience comes from the fact that a card network processes the payment, not from anywhere the money is safer than a bank.

Frequently asked questions

What is the ARQ card?

ARQ is a virtual and physical Mastercard that spends from a digital-dollar balance held in the ARQ app. The card describes itself as a secured credit card backed by the balance in your ARQ account, held in USDc, the digital dollar. It is the former DolarApp, rebranded. It is not a bank account with your own name on it, and the spend limit equals your USDc balance exactly.

How does the ARQ card work?

You get money into your ARQ account, that money is converted to USDc or EURc, and the Mastercard spends from that balance. A hundred dollars of USDc gives you a hundred dollars of card limit — no borrowing, no overdrawing. Payments in any currency are converted at the sell rate, and the app shows that rate before you confirm. It behaves like a prepaid card more than a debit card.

Who can get the ARQ card?

Residents of Mexico, Argentina, Colombia and Brazil, with delivery to a valid address in one of those four countries. The country selector lists exactly those four, and the physical card ships only within them. The specific documents, proof of address and minimum age are not stated on the public pages, and the card cannot be created while identity verification is pending or incomplete.

Is ARQ a bank?

No — it does not present itself as one, and it does not tell you it is. Services run through named companies: virtual asset services by DolarApp México S.A. de C.V., Colombian credit card services by DAPP Colombia S.A.S. (NIT 901644165-9), and a Mexico help page names Pier 5 S.A. de C.V. for credit card services. Licences are not stated on the public pages, which is worth checking yourself before holding a large balance.

Is the ARQ card free?

The virtual card is free. The physical card costs $4.99 USD in shipping, with no maintenance fee and no annual fee. The first physical card is free if you have over $100 USD in Main Balance or you are a Premium user. ATM withdrawals cost 1% of the amount withdrawn, and Premium users get up to 500 USDc per month of that commission waived. Premium pricing is not stated.

What are ARQ’s fees for spending?

A separate FX fee or spread is not disclosed, and the card says it has no hidden fees. What applies is a buy rate when you add money and a sell rate when you pay by card, both shown in the app before you confirm. Payments in another currency are converted at the sell rate. So the cost of conversion is whatever the rate is, and you find out by looking at it rather than from a published figure.

Is the ARQ card safe?

Say “how much trust does it ask for”, not “is it safe”. Safeguards listed are app-based 2FA, an instant card freeze, 3D Secure, PIN viewing and block/unblock controls. What is not stated: the custody model and whether client funds are safeguarded. User reports through 2025-2026 include accounts frozen with funds held, unauthorised charges and slow support. Size your balance so a freeze is an inconvenience, not a crisis.

Does the ARQ card require KYC?

Yes — identity verification must be completed in the app, and the card cannot be created while it is pending or incomplete. That is the whole of what the public pages say: specific documents, proof of address, age thresholds and verification tiers are not stated. Account review can temporarily block card creation, and the reasons for rejection are not given. Verification tiers are not described either.

How do I top up the ARQ card?

You cannot load the card directly. You add money to your ARQ account using the banking details in the app’s “Add” section, and the resulting USDc/EURc balance backs the card. Coins and networks are not stated, and deposit fees and minimums are not stated either — so if you plan to fund it from crypto, the only place to confirm the network is inside the app, before you send.

Can I use the ARQ card abroad and at ATMs?

Yes at ATMs worldwide with the physical card, with one hard exception: cards issued in Argentina are not allowed at international ATMs. The exception applies to the card, not to your location, so an Argentine card will not work abroad. The ATM owner may charge their own fee on top of ARQ’s 1%. Elsewhere you can also add the virtual card to Apple Pay or Google Pay.
