European Card Issuing Platforms

A card issuing platform lets a software company or bank launch its own debit, prepaid or credit cards without becoming a scheme member itself. The platform decides every purchase in real time, so it sees merchants, amounts and cardholder behaviour. The European platforms below are run by companies in the EU and the UK, and they contract under European or UK law.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Vendors can pay for more visibility, higher up on the review pages; it never affects whether a tool is listed. Editorial policy

  • Swan in France prints a starting price of EUR 2,990 per month, and Modulr in the UK prints bundle plans from GBP 30 per month, while the other issuers in this list quote on request.
  • Treezor in Paris can run its card service under the client's own licence, with its BIN sponsor as an optional extra.

A European card issuing platform is a regulated company in the EU, the EEA or the UK that lets a software product, fintech or bank launch debit, prepaid or credit cards under its licence or scheme membership, authorise each purchase in real time, and contract under European law instead of through a US processor.

Every European card issuing platform reviewed

#1 Wallester

Estonia, Estonia White-label pricing on request; business account has a free start tier Demo on request

Best for: Branded card launches by fintechs and software products in the EEA and the UK

  • Operating company. Wallester AS
  • Jurisdiction. EU (Estonia)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Wallester is the Estonian option for teams that want the BIN sponsor and the platform from one company. Wallester AS is a payment institution supervised by the Finantsinspektsioon and an official Visa Principal Member, so a programme runs under its own issuer and scheme framework. A dedicated BIN can be set up where programmes need separate reporting.

The company is registered in Estonia under code 11812882. Its site counts more than 10 million virtual and physical cards issued and names a Latvian national postal service and consumer lenders among its customers, which are vendor statements. Accounts can hold ten currencies, and a white-label app and a back office portal come with the offer.

What Wallester does well

  • Principal membership with Visa, licensed in Estonia
  • Optional dedicated BIN for programme separation
  • Accounts and cards in ten currencies
  • App and back office portal in the offer
  • A retail business account on the same stack

Where Wallester falls short

  • White-label price list must be requested
  • Stated reach ends at the EEA and the UK
  • No self-hosted deployment
  • Credit programme described only in marketing terms

Standout feature. Wallester runs a free-to-start business account for companies on the same infrastructure that carries its white-label card programmes.

#2 Swan

Paris, France Swan on demand from EUR 2,990 per month; Swan Enterprise is custom Demo on request

Best for: Business banking inside accounting, HR or treasury software

  • Operating company. SWAN SAS
  • Jurisdiction. EU (France)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Swan sells embedded banking to software vendors, with cards as one part of a business account. SWAN SAS is registered in Paris under number 853 827 103, and its legal notice calls it an electronic money institution under French law. Local IBANs start with FR, DE, ES, NL or IT.

The pricing page shows Swan on demand from EUR 2,990 per month, while enterprise terms are custom and can include interchange revenue sharing. Programmes cover expense and employee benefit cards with a company logo, in physical, virtual and wallet versions. The sandbox is free and ships with an event simulator and a Postman collection.

What Swan does well

  • Monthly starting price shown on the site
  • E-money licence under French law
  • IBANs for five countries on the cards' accounts
  • No-cost sandbox with an event simulator
  • Revenue sharing from interchange on enterprise terms

Where Swan falls short

  • Floor of EUR 2,990 per month
  • Cards without an account are not described
  • Built for business customers only
  • IBAN coverage limited to five countries

Standout feature. Swan is the only embedded banking vendor here whose public pricing page states a monthly starting fee in euros.

#3 Treezor

Paris, France Pricing on request Demo on request

Best for: Banks, neobanks and benefit-card operators that keep their own licence

  • Operating company. TREEZOR SAS
  • Jurisdiction. EU (France)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Treezor splits card issuing into pieces a regulated institution can rent separately. TREEZOR SAS in Paris (SIREN 807 465 059) lists issuing, processing, tokenisation and printing, to be used under the client's own licence, with its BIN sponsor available if wanted. Its site states an ACPR e-money licence and DORA readiness.

The vendor says it serves more than 150 clients with over 8.5 million cards issued across Europe, and it lists PCI DSS and ISO 27001. A multi-criteria dynamic card selects the funding account per transaction, and external authorisation hands the decision to the client's system. A homepage banner announces that Treezor joins Shares, with no detail on the effect for clients.

What Treezor does well

  • E-money licence from the ACPR
  • Card machinery can run under your own authorisation
  • BIN sponsor offered as an extra
  • Funding account chosen per transaction
  • PCI DSS and ISO 27001 stated by the vendor

Where Treezor falls short

  • No price list on the site
  • Announced change of ownership
  • Four product routes make the offer hard to scan
  • Many pages in French first

Standout feature. Treezor lets a bank hand each purchase to its own system through external authorisation while Treezor handles tokenisation and printing.

#4 Enfuce

Helsinki, Finland Founded 2016 Pricing on request Demo on request

Best for: Larger programmes replacing a legacy processor, including fleet and benefit cards

  • Operating company. Enfuce Financial Services Ltd
  • Jurisdiction. EU (Finland)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Enfuce is the Nordic issuer processor on this list and the one built for programmes of some scale. Enfuce Financial Services Ltd was founded in 2016 in Helsinki, holds an e-money licence from the FIN-FSA passported across the EEA, and is a principal member of Visa and Mastercard. Its UK operations are authorised separately by the FCA.

The vendor states 29 million cardholders, 99.999 percent uptime and an average response of 160 milliseconds, with infrastructure separated per programme. Customers named include Pleo, Swile, Avida, SEB Embedded and Porsche. Investors include Vitruvian Partners, Maki.vc, Tencent and Visa. No price or minimum programme size is published.

What Enfuce does well

  • FIN-FSA licence valid across the EEA
  • Membership with both Visa and Mastercard
  • EV charge, fuel and multi-PAN cards listed
  • Separate infrastructure for each programme
  • Licensing, ledger and disputes in one stack

Where Enfuce falls short

  • Neither price nor minimum is published
  • Suits larger programmes more than small launches
  • Non-European investors in the cap table
  • Little developer material in public

Standout feature. Enfuce lists EV charge and fuel cards next to the usual card types, which matters to mobility and fleet programmes.

#5 Paynetics

Sofia, Bulgaria Pricing on request Demo on request

Best for: Program managers and PSPs that prefer renting a sponsor to holding a licence

  • Operating company. Paynetics AD
  • Jurisdiction. EU (Bulgaria)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Paynetics is the Bulgarian sponsor for programmes that want a BIN without scheme membership of their own. Paynetics AD (company number 131574695) is licensed by the Bulgarian National Bank, passported across the EU, and a principal member of Visa and Mastercard. A UK subsidiary, Paynetics UK Ltd, holds an FCA e-money licence.

Its pages list prepaid, debit, credit, business, virtual and tokenised cards, and use cases such as gift cards, payroll incentives, government disbursement and cards for minors. Acquiring and open banking sit in the same company. Weavr names Paynetics as the issuer of its EU Mastercard cards. A homepage banner warns about misuse of the name by an unrelated lender.

What Paynetics does well

  • Bulgarian National Bank licence passported in the EU
  • Principal membership with both card schemes
  • Many card types and programme use cases named
  • Merchant acquiring offered by the same entity
  • FCA-licensed UK subsidiary

Where Paynetics falls short

  • Prices are not published
  • Product pages read as marketing copy
  • Warning about name misuse shown on the homepage
  • Technical content outside the API docs is thin

Standout feature. Paynetics explains BIN sponsorship in plain terms and is the issuer behind another vendor on this list, Weavr.

#6 Weavr

London, United Kingdom Pricing on request Demo on request

Best for: Expense, benefit and supplier-payment cards inside B2B software

  • Operating company. Weavr Ltd and Weavr (Europe) Ltd (Paystratus Group Limited)
  • Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Weavr starts from the workflow instead of the card catalogue. Its site is organised around employee benefits, expenses, accounts payable, SaaS subscriptions, loyalty, gifting and travel, and delivers accounts, payments and cards as a headless layer. Weavr Ltd (England, 13433581) serves UK entities and Weavr (Europe) Ltd (Malta, C98895) serves EU entities.

Both companies are owned by Paystratus Group Limited in London. For EU programmes the account and Mastercard card come from Paynetics AD, with Weavr (Europe) acting as registered agent, so the regulatory chain has one more link than with a direct licence holder. The Embedder Portal sandbox and a public changelog are published, while prices are not.

What Weavr does well

  • Packaged around business software workflows
  • Sandbox and changelog open to read
  • Contracting entities for the UK and for the EU
  • Virtual cards for travel and loyalty cases
  • Headless, so the interface stays in your product

Where Weavr falls short

  • Price not shown anywhere on the site
  • EU programmes rely on a partner issuer
  • Consumer launches are outside the pitch
  • Short list of card types

Standout feature. Weavr contracts UK programmes with Weavr Ltd and EU programmes with Weavr (Europe) Ltd, and states the split in its footer.

#7 Solaris

Berlin, Germany Pricing on request Demo on request

Best for: Software, travel and mobility brands that want a bank behind consumer cards

  • Operating company. Solaris SE
  • Jurisdiction. EU (Germany)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Solaris is the full bank among the dedicated issuers. Solaris SE, based at Cuvrystrasse 53 in Berlin, names BaFin and the European Central Bank as supervisory authorities in its imprint and calls itself a German technology company with a full banking licence. Cards run on Mastercard and Visa in physical, virtual, tokenised and metal formats.

Debit, prepaid and credit are offered, with credit as charge or revolving products based on scoring, and cards can be issued with or without an underlying account. Offers are grouped by industry, including SaaS, ERP, HR tech, travel and mobility, and a KYC and KYB platform is sold alongside. Ownership is not shown on the pages read.

What Solaris does well

  • Banking licence with BaFin and ECB supervision
  • Mastercard and Visa both available
  • Debit, prepaid and credit under one roof
  • Account optional behind the card
  • Metal and eco materials for card bodies

Where Solaris falls short

  • No public price list
  • Onboarding is a project, not a signup
  • Shareholders not visible on the pages read
  • Wider than a card-only buyer needs

Standout feature. Solaris names BaFin and the ECB in its imprint, which no other dedicated card issuer on this list does.

#8 Modulr

United Kingdom, United Kingdom Bundle plans from GBP 30 per month (Bronze), GBP 110 (Silver), GBP 500 (Platinum); platform pricing separate Demo on request

Best for: UK company cards next to accounts, pay-outs and accounts payable

  • Operating company. Modulr Finance Limited / Modulr FS Limited
  • Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Modulr is a UK payment automation platform with company cards as one product beside accounts and pay-outs. Modulr Finance Limited (England, 09897957) acts as agent of Modulr FS Limited (09897919), which the FCA authorises as an electronic money institution. The site serves businesses buying plans and platforms using the API, in English, Spanish and French.

The pricing page lists Bronze at GBP 30 per month with 80 payments, Silver at GBP 110 with 500 and Platinum at GBP 500 with 3,000, plus per-payment fees above the allowance. Virtual and physical company cards are offered, with a sandbox for platform builders. An own-BIN programme, consumer cards and credit are not described.

What Modulr does well

  • Bundle tiers priced on the website
  • Regulated entity under the FCA
  • Cards sold with accounts and pay-outs
  • API with a sandbox
  • Accounts payable and payroll tooling

Where Modulr falls short

  • Prices in pounds, entities in England
  • Own-BIN programmes not described
  • Consumer and credit cards are absent from the list
  • Platform pricing for enterprise is on request

Standout feature. Modulr publishes plan tiers with payment allowances, which makes cost forecasting possible before a sales call.

#9 Thredd

London, United Kingdom Pricing on request Demo on request

Best for: Processing and ledger for issuers that hold or arrange their own licence

  • Operating company. Thredd UK Limited
  • Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
  • Where the data sits. Not specified on the vendor pages checked
  • Source code. Closed source
  • Replaces. Marqeta, Stripe Issuing, Lithic

Thredd sells the processing layer and is the one on this list that says so in its first line. Thredd UK Limited (company number 09926803) uses a Kingsway address in London and describes a bank-grade issuer processing platform for credit, debit and prepaid programmes, with virtual cards, a system of record, card controls, wallets and risk tools.

It lists PCI DSS, ISO 27001, ISO 22301, ISO 31000 and SOC 1 and SOC 2 Type II, and states B Corp certification. Investors shown include Advent, Viking, Temasek, MissionOG, Visa and Mastercard. The pages read name no regulator and give no prices, and the main domain sat behind a bot check, so facts come from thredd.ai and the documentation portal.

What Thredd does well

  • Positioned as a processor first
  • Documentation portal open to everyone
  • Certifications named on the site
  • Credit, debit and prepaid programmes
  • Sponsorship option for clients without a licence

Where Thredd falls short

  • Prices are not stated
  • Regulators missing from the pages read
  • Ownership split not shown
  • Moved recently from thredd.com to thredd.ai

Standout feature. Thredd keeps its developer documentation, key concepts guide and getting started material open to read before any sales contact.

#10 Checkout.com

London, United Kingdom Founded 2012 Custom flat-rate or interchange-plus pricing quoted per merchant; no setup, monthly or account fee; free processing for registered charities Demo on request

Best for: Larger merchants wanting issuing beside acquiring under one contract

  • Operating company. Checkout Ltd
  • Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
  • Where the data sits. UK/EU
  • Source code. Closed source
  • Replaces. Stripe, Adyen, Braintree

Checkout.com offers card issuing next to its acquiring product, on Visa and Mastercard. Checkout Ltd is registered in England and Wales (08037323), was founded in 2012 by Guillaume Pousaz, and is authorised by the FCA as an e-money institution. A French entity, Checkout SAS, holds a separate ACPR licence for EEA customers.

The pricing options are flat rate or interchange-plus, quoted per merchant, with no setup, monthly or account fee and free processing for registered charities. Card processing is PCI DSS Level 1 certified. Onboarding runs through a sales process, and the issuing-specific contracting entity is not stated on the pages read.

What Checkout.com does well

  • Gateway, acquiring and issuing reachable through one API
  • UK e-money licence plus a French licence for the EEA
  • Level 1 PCI DSS certification
  • Registered charities process free of charge
  • No setup, monthly or account fee on either model

Where Checkout.com falls short

  • Rates are quoted case by case
  • Sales-led onboarding, no self-serve start
  • Targets bigger merchants, not small ones
  • Interchange-plus is harder to forecast than a flat rate

Standout feature. Checkout.com combines an FCA licence in London with a separate ACPR licence in France for its EEA customers.

#11 Adyen

Amsterdam, Netherlands Founded 2006 Custom pricing Demo on request

Best for: Global enterprises that want issuing on the platform that already acquires for them

  • Operating company. Adyen
  • Jurisdiction. EU (Netherlands)
  • Source code. Closed source
  • Replaces. Stripe, Braintree

Adyen puts issuing on the same platform as its acquiring and risk products. The Dutch company was founded in 2006, has been listed on Euronext Amsterdam since 2018, and holds a Dutch banking licence with funds held in segregated accounts. Its issuing offer lists integrated BIN sponsorship and spend rules on a single integration.

The platform supports over 250 payment methods and more than 175 currencies, and RevenueProtect fraud scoring runs inside the payment flow. Pricing is custom, interchange-plus and enterprise-oriented, with no self-serve signup. Which Adyen entity contracts for issuing in each region is not verified on the pages read.

What Adyen does well

  • Online, in-store, risk and issuing share one data layer
  • Dutch bank licence with segregated client funds
  • 250+ payment methods in 175+ currencies
  • Fraud scoring built into the payment flow
  • Interchange-plus rates fall as volume grows

Where Adyen falls short

  • Mid-market and enterprise focus, historic volume minimums
  • Sales process instead of self-serve signup
  • Interchange-plus pricing is hard to forecast
  • More platform than a small programme needs

Standout feature. Adyen runs issuing, acquiring and fraud scoring on one platform with a shared data layer.

#12 Nexi

Milan, Italy Founded 2017 Enterprise and SME pricing quoted per merchant or bank; no published rate card Demo on request

Best for: Banks and large companies buying card issuing as infrastructure from a listed group

  • Operating company. Nexi S.p.A.
  • Jurisdiction. EU (Italy)
  • Source code. Closed source
  • Replaces. Worldpay, Fiserv, Global Payments

Nexi supplies card issuing to partner banks and companies from Milan. Nexi S.p.A. was formed in 2017 from ICBPI and CartaSi, grew through the combination with Nets and SIA, and listed on Borsa Italiana in April 2019. Its issuing page names credit, debit and prepaid cards and mobile wallets, and it also sells acquiring and digital banking.

Operations extend across a dozen European markets. No shareholder holds a majority: a vehicle linked to the US private equity firm Hellman & Friedman holds just over 20 percent, and Cassa Depositi e Prestiti close to 19 percent. Pricing is negotiated per bank or merchant, with no published rate card.

What Nexi does well

  • Merger of ICBPI/CartaSi, Nets and SIA into one group
  • Public company since 2019 without a controlling holder
  • Acquiring, issuing and digital banking together
  • Activity in about twelve European countries
  • Provides infrastructure for banks as well as merchants

Where Nexi falls short

  • Negotiated engagements only, with no self-serve route
  • Rates are never published
  • Poor fit for a merchant starting this week
  • The biggest shareholder is tied to a US buyout fund

Standout feature. Nexi was assembled from three national payment infrastructures, Italian, Nordic and pan-European, into one listed group.

How do I choose between a sponsor, a processor and an embedded banking platform?

Start with who holds the licence. A sponsor such as Wallester, Paynetics or Solaris gives you a BIN and scheme access under its own membership, so you do not need an authorisation of your own. A processor such as Thredd or Enfuce runs authorisation, a ledger and settlement for an issuer that already has, or arranges, a licence. An embedded banking platform such as Swan or Weavr packages accounts and cards for software products.

Then look at what sits behind the card. Swan presents cards as part of business accounts, Modulr as one piece of payment automation, and Treezor as a separable service that works with the client's own licence. If your product has no accounts at all, ask each vendor whether a card-only programme exists, because Swan does not describe one and Solaris says cards can run with or without an account.

What do card issuing platforms cost, and which ones publish prices?

Only two vendors on this list show a number. Swan states Swan on demand from EUR 2,990 per month, with enterprise terms that can add interchange sharing and custom card design. Modulr lists Bronze at GBP 30, Silver at GBP 110 and Platinum at GBP 500 per month, and separates platform pricing, which is on request.

The rest quote after a conversation. Wallester says white-label pricing is on request while its business account has a free start tier, and Checkout.com quotes flat-rate or interchange-plus per merchant with no setup, monthly or account fee. Expect programme fees, per-card fees and a share of interchange to be negotiated together, and ask for all three in the first quote.

Which jurisdiction and regulator will sit in my card chain?

It differs by vendor. Wallester answers to the Estonian Finantsinspektsioon, Treezor and Swan are French e-money institutions, Paynetics is licensed by the Bulgarian National Bank, Enfuce by the Finnish FIN-FSA, and Solaris names BaFin and the ECB. Nexi is an Italian listed group, and Adyen holds a Dutch banking licence.

Three vendors are UK-based: Modulr, Thredd and Weavr, plus Checkout.com in London. The UK is covered by an adequacy decision but sits outside the EEA. Weavr states that EU programmes use Paynetics AD as the issuer with Weavr (Europe) Ltd as registered agent, and Checkout.com pairs its FCA licence with a French ACPR licence for EEA customers. Ask each UK vendor which entity signs your EU programme.

How do I migrate cards away from Marqeta, Stripe Issuing or Lithic?

Treat it as a re-issue project. Cards carry the BIN of the old sponsor, so a new issuer normally means new card numbers or a negotiated migration, and wallet tokens must be provisioned again. Enfuce lists migration as an expertise for banks leaving a legacy processor, which makes it the first stop for a large existing portfolio.

For a smaller programme, run the new issuer in parallel and move new cardholders first. Swan offers a free sandbox with an event simulator, and Weavr offers an Embedder Portal sandbox and a public changelog, so authorisation and webhook code can be tested before any live card exists. The pages reviewed do not publish migration timelines for any vendor.

When is staying with a US issuer the better choice?

Stay if the programme must issue in the United States or Asia-Pacific. Wallester's pages describe the EEA and the UK, and none of the twelve European vendors here documents a coverage footprint beyond Europe comparable to a global US processor. Staying also makes sense when a migration would interrupt a live portfolio and no regulator or customer requires a European contracting party.

The European case is strongest when your cardholders are in the EEA or UK, when your own supervisor expects a European entity in the chain, or when you want a licence holder rather than a partner bank between you and the scheme. Weigh those requirements first, then compare vendors on cost and features.

Which platforms fit a bank, a fintech, a SaaS product or a merchant?

Banks with their own licence fit Treezor, Enfuce and Thredd, which sell processing and card services around an existing authorisation. Fintechs that need a sponsor fit Wallester and Paynetics. SaaS products adding cards for business customers fit Swan, Weavr and Modulr, and brands wanting a bank behind consumer or travel cards fit Solaris.

Merchants that already accept payments can look at Checkout.com, Adyen and Nexi, where issuing sits next to acquiring. All three sell through sales teams without self-serve signup, so they suit larger volumes rather than a first launch.

How we selected and ranked these 12 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

  1. Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
  2. Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
  3. Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
  4. Editorial review. Every page is researched and drafted with AI assistance, and the compliance and pricing claims are checked against the vendor's documentation before it is published under the founder's editorial responsibility. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — ROI figures, margin uplift, time saved — are labelled as vendor claims wherever they appear on this page. We have not audited them, and neither has anyone else who quotes them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

It depends on the programme, since no single vendor fits every case. Wallester and Paynetics suit teams that want a BIN sponsor, Swan and Weavr suit software products that embed business accounts or cards, Treezor and Enfuce suit banks and larger portfolios, Solaris suits brands wanting a German bank licence, and Modulr suits UK company cards.

Swan states a start of EUR 2,990 per month and Modulr lists GBP 30, GBP 110 and GBP 500 monthly bundles. Wallester, Treezor, Enfuce, Paynetics, Weavr, Solaris and Thredd quote on request, and Checkout.com, Adyen and Nexi quote per merchant or bank.

The reviewed pages do not describe one. Wallester, Paynetics and Enfuce state principal membership in Visa or Mastercard under European licences, Treezor offers its own BIN sponsor, and Solaris is a bank. Weavr adds Paynetics as its EU issuer. Ask each vendor where authorisation is processed if that matters to you.

Yes for several. Wallester states EEA and UK coverage, Enfuce is authorised by the FCA for its UK operations, Paynetics has a UK subsidiary under an FCA licence, and Modulr, Thredd, Weavr and Checkout.com are UK companies. Contracting entities differ for the UK and the EU, so check which one signs.
