The Slash card is pitched as Japan’s first credit card usable with stablecoins, a Visa that lets you spend USDC at the till and have the merchant paid in yen. The product exists, the partnership with Iquitous and Orico has been announced, and the public launch reached the general public in mid-October 2026. Beyond those facts, the picture thins quickly: the public pages do not state conversion or FX fees, ATM behaviour, daily and monthly limits, or whether the card joins Apple Pay or Google Pay. This review walks through what Slash does say, what it leaves out, and what that means if you are weighing it against a crypto card you can actually use abroad.

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

Verdict

Slash earns 4.6 out of 10. The number reflects the gap between what the product tries to be, a stablecoin Visa usable in stores, and what its public information actually lets a reader judge. On the positive side, USDC top-up works on two real networks (Solana and Ethereum), virtual issuance is instant, and a physical card exists for Japan residents. On the negative side, the card is open only to residents of Japan, identity verification accepts a Japanese driver’s licence, physical cards ship only within Japan, and many of the everyday numbers a reader needs to make a decision (conversion, FX, ATM, limits, Apple Pay, Google Pay) are not stated on the card’s pages.

The card fits a narrow reader: someone in Japan, 18 or older, who already holds USDC, who wants to spend it at a contactless terminal or online without manually converting each purchase, and who is comfortable that the fee structure is not spelled out. It does not fit a reader outside Japan, a reader who wants to compare fees in writing before signing up, or a reader who needs mobile wallet support confirmed.

Here is the score broken down by criterion.

Who will they give you the card to

Slash is built around residency, not citizenship. The card’s own pages say accounts are available to residents of Japan aged 18 and over, and that physical cards ship within Japan. There is no list of supported countries because there is only one: Japan. If you live in Tokyo, Osaka, Sapporo or anywhere else in the country, you can apply. If you live anywhere else, you cannot.

The identity step is called *honnin kakunin* in the app. News coverage of the launch mentions a Japanese driver’s licence and biometric authentication as the typical path, and the more recent general-public opening added driver’s licence acceptance for ID. Whether other documents are accepted, and what the proof-of-address requirement is, is not stated on the card’s public pages. Treat any specific document list as unofficial until you see it in the app’s verification flow.

A practical consequence: Slash is the kind of card that helps a reader who already has a Japanese address and a Japanese ID document, and who wants to spend a USDC balance domestically. It is not a card that helps a frequent traveller, an expat whose residence is outside Japan, or a non-resident who wants yen exposure. For those readers, the “Who can get it” question is the first one the card answers for them, and the answer is no.

How to get it

The signup path is the standard crypto-card shape: app, verify, get a card. You download the Slash App on iOS or Android, create an account, complete identity verification inside the app, and then issue a virtual card. The virtual card is available immediately after verification. A physical Visa card is also available, and you may have more than one of each.

The product page calls Slash “Japan’s first credit card usable with stablecoins”. What that phrase means in practice is that the card sits on a Visa credit rail, and the underlying balance is USDC, while the merchant is paid in yen. Whether Slash is technically a credit, debit or prepaid product at the network level, the card currency the merchant sees, and the FX treatment of cross-border spending, are all not stated.

The partnership stack behind the card, drawn from press releases, is worth noting because it explains who is actually on the hook. Iquitous (iKitas) Inc. is the card issuer and runs customer management. Slash Vision Pte. Ltd., based in Singapore, is the programme manager and the brand. Orico is the BIN sponsor and provides international brand support. The partnership was announced on 13 February 2025, pre-applications opened in June 2025, issuance began on 20 April 2026, and a general-public opening was reported around 15 October 2026.

What the public pages do not cover:

• proof of address documents accepted during verification
• identity document types beyond driver’s licence
• whether the same person can hold more than one account
• shipping time and shipping cost for the physical card
• replacement procedure for a lost or stolen physical card
• whether verification has tiers (for example different limits for different document types)

If any of those matter to you, expect to find out in the app or from support, not from the marketing site.

What it really costs

Slash’s public pricing is partial. Some numbers are clear, some are simply not stated, and that mix is the most important thing to understand before you sign up.

Here is what the card charges in writing.

A few everyday scenarios, run against what is and is not in the table.

You buy a coffee with your physical card. The merchant sees a Visa transaction in yen. The card needs to turn your USDC into something that pays the merchant. The fee for that conversion, if any, is not stated on the card’s pages. You cannot pre-compute the cost of the coffee in USDC because the rate and the fee that apply at the moment of authorisation are not published. You can be told the headline number (the card is free to open, the physical card is 35 or 70 USDC) and that is genuinely all.

You use the card while travelling outside Japan. The site does not say whether the card supports foreign spend at all, and it does not say what the foreign transaction fee would be. The physical card ships only within Japan, so this scenario is mostly about the virtual card, and again the fee schedule is not stated.

You want to withdraw cash from an ATM. The card’s pages do not say whether ATM withdrawals are allowed, what they cost, or what the daily ATM limit is. Treat ATM access as “not confirmed” until you see it in the app or in a terms document you can read before signing up.

The reward side is equally thin. There is no published cashback. The card does have a referral: a friend issues a card and makes a first payment, and the referrer receives a reward. Unofficial reporting mentions a reward of about USD 10 equivalent per friend, but that figure is from third-party news and is not confirmed by the card. The card also mentions member tiers “coming soon”, with planned perks that may include up to 1.5% in some unofficial reporting. Treat any specific tier or cashback number as unofficial until it shows up in the app.

One last cost worth flagging. The card’s annual fee is free in the first year and 20 USDC from year two. That is a recurring charge in USDC, and the way the fee is taken is not described in detail on the public pages. If you keep the card for several years, the 20 USDC per year is the only cost you can plan around with certainty.

How to top it up

Top-up is the cleanest part of Slash’s public story. You fund the card with USDC, in the app, on two networks that work today.

• Solana — supported
• Ethereum (ERC-20) — supported
• Base — “coming soon”
• Arbitrum — “coming soon”
• HyperEVM — “coming soon”

So a reader who already holds USDC on Ethereum or Solana can move it into the card by sending it to the deposit address shown in the app. A reader whose USDC lives on Base, Arbitrum, Polygon, Tron, Avalanche or any other chain will have to bridge or swap to one of the supported networks first, paying network and slippage costs along the way. Circle stopped supporting USDC on Tron in February 2024, and Slash does not list Tron as a supported top-up network either.

What the public pages do not say about top-up:

• minimum top-up amount
• top-up fee (the card may charge one, or it may not)
• fiat on-ramp inside the app, that is, whether you can buy USDC with a Japanese bank transfer or a card payment without leaving Slash
• withdrawal back out to your own wallet
• how long a top-up takes to land and become spendable

Network fees are charged by the blockchain, not by Slash, so on Ethereum you will pay gas in ETH, and on Solana you will pay a small SOL fee. ERC-20 transfers need a wallet that holds ETH for gas, which a reader with only USDC will need to address before the first top-up.

Paying with it every day

The card behaves like a normal Visa at the till. The press coverage and the card’s own pages describe contactless payment in stores and online card payment on websites. The virtual card is issued immediately after verification, so you can start spending online without waiting for the post. The physical card supports contactless in stores.

In the app, you can freeze the card instantly if it is lost or stolen. That is a standard safeguard and is the one part of card management the card spells out clearly.

What the public pages do not say about daily use:

• Apple Pay support and Google Pay support
• which merchant category codes (MCCs) are blocked, for example gambling
• whether the card supports 3-D Secure, and whether online merchants will see the same friction or smooth flow as a Japanese-issued Visa
• dispute and chargeback process, and the documents the cardholder needs to provide
• whether the app shows a real-time transaction feed, and whether it pushes notifications
• how the card appears in Apple Wallet or Google Wallet if mobile wallet support is added later

The dispute question matters more than the marketing suggests. Crypto cards have a mixed record here: some programmes make chargebacks straightforward, others hide the dispute path behind a help-centre category. The card’s help centre is on Zendesk, with categories for issuance guide, usage guide and terms and policies, all in Japanese, and that is the public surface. Whether disputes are handled in English, in what timeframe, and with what evidence requirements, is not stated.

What can go wrong

There are three layers of risk to weigh.

Programmatic and product risk. Slash is a new product. The card was announced in February 2025, pre-applications opened in June 2025, issuance to first customers began on 20 April 2026, and the general public opening was reported around 15 October 2026. That timeline itself is one of the data points: the launch slipped from an earlier 2025 target to 2026. Independent reviews and complaints are not found at the time of writing. Most of the public coverage is press-release based.

Compliance and shutdown risk. A crypto card can stop working not because the product is bad, but because its issuer, BIN sponsor or programme manager runs into trouble. The general background section below sets out the precedents: WaveCrest was suspended by Visa in Europe in 2018, FTX’s card was wound down in November 2022, and other programmes have given a notice period, then stopped loading, then stopped spending. Slash’s pages describe strict identity verification, transaction monitoring, and alignment with international AML standards, the Installment Sales Act and the Act on Prevention of Transfer of Criminal Proceeds in Japan. That is the right shape of language to see, but it does not eliminate the structural risk that any programme can be paused or closed by Visa, Mastercard, the BIN sponsor or the regulator.

Information risk. The public surface of the card does not state conversion, FX, ATM, daily or monthly limits, mobile wallet support or dispute handling. A reader who signs up on the strength of the headlines is signing up without seeing the part of the contract that usually catches readers out. The reasonable way to read the card is to assume there is more in the terms than there is on the marketing page, and to ask support to confirm the numbers that matter to you before paying the 35 or 70 USDC issuance fee.

Two smaller practical risks to keep in mind.

• A card issued in Japan will look “foreign” to many overseas merchants. The merchant’s BIN lookup shows the issuer country, and many online shops are stricter with cards whose issuer country differs from the billing address. AVS, the address check used mainly in the US, Canada and the UK, is generally unavailable for foreign-issued cards, which can cause declines that have nothing to do with your balance.
• Stablecoin-funded cards are exposed to depeg risk. USDC has held its peg well in normal conditions, but the March 2023 US banking stress saw USDC briefly lose its peg. Tether says it disables tokens in sanctioned wallets and has frozen funds tied to illicit activity, which means stablecoins are not censorship-proof.

What to take instead

Slash is one of the narrower crypto cards on the market today. If Slash’s residency, fee transparency or network list does not match your situation, three other products are worth weighing.

MetaMask Card (7.1 / 10). Sign-up is open in 45 listed countries and territories, including several in Europe, the Americas, Asia and Oceania, while other regions join a waitlist. The card is Mastercard, virtual issuance is instant, and a Metal tier can be pre-ordered in the app. The issuer is Monovate and the card provider is Crypto Life. The Virtual tier is free with no annual or maintenance fee; the Metal tier is $199 a year. Cashback is paid in mUSD into the Money Account: 1% on Virtual and a headline 3% on Metal (footnote limits 3% to the first $10,000 spent, then 1%). The card spends directly from a connected wallet on Linea, Base, Monad and Solana, with named tokens including mUSD, wETH, EURe, GBPe, USDC and USDT. The downsides worth knowing: US and UK sign-ups are temporarily closed per the FAQ, and one card per user. MetaMask Card is the strongest general-purpose alternative if you are outside Japan.

KAST (6.1 / 10). Residence-based availability: KYC is gated to a list of supported countries that the site does not publish in full, and an unsupported country can still create an account but cannot pass KYC. The card line-up is the broadest in this comparison: up to 10 cards per user, virtual and physical, including Visa Platinum (Standard), Visa Infinite metal (Premium) and Visa Infinite gold plated (Private), plus themed designs. The annual membership is 0 USD for Standard, 1,000 USD/year for Premium and 10,000 USD/year for Private, billed annually. Stablecoin top-up is 0%, USD-denominated card spend is 0%, and non-USD FX is 0.5%–1.75% depending on residence country, transaction country and card programme. Cashback in USD is tiered: 1.5% on Standard (first 2,000 USD/month), 2% on Premium (first 10,000 USD/month), 3% on Private (first 40,000 USD/month), with extra KAST Points on the upper tiers. KAST is the alternative to look at if you want clear published FX fees and tiered cashback.

TokenPocket (5.8 / 10). A Visa debit option for a list of European countries and territories (Germany, France, Spain, Switzerland, among others) and a Mastercard debit option for Australia, Canada, Hong Kong, Japan, Singapore, South Korea, Taiwan, New Zealand, the UK and others; the Americas are planned for Q2 2025. Balances are held in EUR24 and USD24. The card does not publish additional fees beyond an NFT creation fee partly covered by TokenPocket (the user pays “a small portion”, amount not stated) and a 1% fee on crypto deposits into the TP Card, which is “to be refunded later via rewards, reduced transaction fees, etc.”. Fiat24 cards are virtual; no physical card is mentioned. FX fees and any extra fees from inter-institution settlement are not stated. TokenPocket is the alternative to weigh if you are in one of its supported countries and you are comfortable with a deposit-fee-refunded-via-rewards structure.

If you are outside Japan and want a Visa or Mastercard funded from a self-custodial wallet, MetaMask Card is the more direct answer. If you want published FX fees and you can meet the annual membership, KAST is the more transparent one. If you live in one of TokenPocket’s supported countries, its 1% deposit fee structure is the trade you would be making.

Who I would recommend it to

The card is worth a closer look if all of the following are true.

• You live in Japan, are 18 or older, and can complete *honnin kakunin* with a Japanese ID document such as a driver’s licence.
• You already hold USDC on Solana or Ethereum, and you do not mind the cost of bridging to one of those networks if you are on a different chain.
• You mainly spend in yen inside Japan, at contactless terminals or online, and you do not need a card that travels with you.
• You are comfortable that the conversion fee, FX fee, ATM behaviour, daily and monthly limits, Apple Pay and Google Pay support, and dispute process are not stated on the public pages, and you are willing to confirm those numbers in the app or with support before you pay the 35 or 70 USDC issuance fee.

The card is worth skipping if any of the following are true.

• You live outside Japan. The product is not for you.
• You need to see the full fee schedule in writing before signing up. Slash does not publish conversion, FX, ATM or limit numbers.
• You need Apple Pay, Google Pay, ATM access, or a clear dispute path. None of these are confirmed.
• You want self-custody. The card is custodial: it holds your USDC, and you take counterparty risk on Slash Vision Pte. Ltd. and Iquitous. The custody model is not described in detail on the card’s pages.
• You hold USDC on Base, Arbitrum, Polygon, Tron, Avalanche or any other chain, and you do not want to pay bridging and slippage costs to move it to Solana or Ethereum.

In short: Slash is a Japan-domestic stablecoin Visa with a thin public surface. For a Japan-resident reader who already holds USDC and wants to spend it at home without manually converting each time, it is a real product to test. For everyone else, the comparison above is a better starting point.

Background: how crypto cards work

A payment card number is built from a six- or eight-digit issuer identification number (the BIN or IIN) that names the issuing institution, an account identifier and a check digit. The merchant’s payment processor looks up the BIN to learn the card type and the issuer country, and many online shops apply extra scrutiny when the issuer country differs from the customer’s billing address, which is one reason a card issued in one country can look “foreign” to a shop in another.

A prepaid card draws on a stored balance; a standard debit card pulls funds from a linked bank account at the time of purchase. Many crypto cards behave like prepaid cards: the user tops up a fiat or stablecoin balance and the card spends that balance only, so it cannot overdraw. Behind the card are several parties: the network (Visa or Mastercard) routes the messages and sets the rules, a licensed issuer holds the card programme, and a programme manager — often the crypto brand itself — markets the card and runs the app. Visa and Mastercard do not issue cards to consumers directly, and either can suspend a programme: in November 2022 Visa said it had “terminated our global agreements with FTX”, and the FTX US debit card was wound down by its issuer; in 2018, WaveCrest was suspended by Visa in Europe, closing all WaveCrest-issued Visa programmes.

Custody is the line that decides who actually holds your money. A custodial wallet means the provider holds the credentials, so the user must trust the provider completely; a seed phrase of 12 to 24 words is an unencrypted form of the private key, and anyone who has it can spend the funds. Crypto transfers are typically irreversible, and a stolen private key has no built-in recovery. Custodial platforms have failed in the past: Mt. Gox (around US$350 million reported stolen between 2011 and 2014), Coincheck (around US$400 million in 2018) and Ronin Network (US$625 million in 2022). With a self-custody-linked card the funds stay in the user’s own wallet until the moment of payment, but the user alone carries the cost of key loss, phishing and clipboard-hijacking malware.

KYC rules ask regulated businesses to verify customers and to monitor transactions for AML and counter-terrorism-financing purposes. In the EU, customer due diligence covers name, address, date of birth, nationality and identity documents, plus a sanctions check, a stated purpose of the relationship and a politically exposed person (PEP) check. In the US the customer identification programme requires name, date of birth, address and an identification number. Nationality is screened separately from residence because sanctions and issuer risk policy often apply to citizenship and country of birth as well as country of address. Where due diligence cannot be completed, institutions are required to refuse the relationship and may close existing ones, which is why accounts are frozen pending documents. Prepaid and debit cards are generally available to adults aged 18 and over, with some issuers setting higher limits.

In the EU, MiCA (Regulation (EU) 2023/1114) took legal effect in June 2023; the rules on asset-referenced and e-money tokens (stablecoins) applied from 30 June 2024 and the remaining provisions, including the crypto-asset service provider (CASP) rules, applied from 30 December 2024. E-money tokens may be issued only by a credit institution or an electronic money institution. A CASP authorised in one member state can serve the EU. A payment card itself is a payment service, regulated separately, so a crypto card often depends on two licences. EMIs must safeguard customer funds by segregation or insurance, but those funds are not the same as bank deposits and may not be covered by deposit guarantee schemes. In the US, FinCEN guidance (FIN-2013-G001) treats administrators and exchangers of convertible virtual currency as money transmitters.

Stablecoins aim to hold a stable value against a fiat currency, but they are not necessarily stable. Tether’s USDT and Circle’s USDC are US-dollar-pegged, and the BIS put about 90% of stablecoin market capitalisation in these two in July 2025. Circle says USDC is redeemable 1:1 for USD and 100% backed by cash and cash equivalents, mostly in an SEC-registered government money market fund, with monthly reserve attestations by a Big Four firm, and Circle lists USDC as natively supported on 38 networks including Ethereum, Solana, Base, Polygon PoS, Avalanche, Arbitrum and Stellar. Stablecoins can depeg: TerraUSD collapsed in May 2022, and USDC temporarily lost its peg in March 2023 during the US banking crisis. Tether says it disables tokens in wallets on the OFAC sanctions list and has frozen funds tied to illicit activity, which is why stablecoins are not censorship-proof.

On the technical side, ERC-20 is the Ethereum token standard (proposed November 2015), and fees on Ethereum are paid only in ETH, so a wallet with USDT but no ETH cannot send. Tron’s network uses bandwidth and energy as internal resource pricing, and Circle stopped supporting USDC on Tron in February 2024. Blockchain transfers are irreversible, so a deposit sent on a network the card provider does not support, or to an address of another network, can be lost or need manual support recovery with no guarantee.

For card payments, the merchant category code (MCC) is a four-digit number classifying a business, and MCC 7995 covers gambling. Many issuers block specific MCCs by policy rather than by law, and the blocked list varies. 3-D Secure adds an identity check to online payments (Visa Secure for Visa, Identity Check for Mastercard). Address Verification Service (AVS) is mainly offered in the US, Canada and the UK, and is generally unavailable for foreign-issued cards, which can cause declines. Apple Pay replaces the card number with a device-specific Device Account Number stored in the Secure Element, and each payment uses a one-time dynamic security code. A chargeback is a refund ordered by the card issuer, with reason codes for fraud, duplicate billing or goods not received; US debit reversal rights come from Regulation E, credit card rights from Regulation Z, and prepaid-card coverage varies.

For tax, the IRS treats digital assets as property, so exchanging them for goods, services, dollars or other digital assets generally produces a taxable gain or loss, measured in local fiat using fair market value on the transaction date.
