Card Machines for Bad Credit UK 2026: 5 Providers Compared

Getting a merchant account with poor credit – or no credit history at all – is far easier in 2026 than it was just a few years ago. The shift comes down to one key distinction: Payment Service Providers (PSPs) like Square, SumUp, and PayPal POS (formerly Zettle) don’t issue individual merchant accounts. Instead, they pool merchants under a shared account and bear the underwriting risk themselves, so their onboarding rules differ from a traditional merchant account. Credit-check policies still differ by provider: Square says no credit checks are required, Tide says its business account has no hard credit check, and PayPal Point of Sale says it performs a credit check to verify your identity.

Sign-up is online and usually quicker than a traditional merchant account, but every provider verifies your identity and business before you can take payments. Square says verification takes minutes; SumUp says it typically takes 1-3 business days. If you are a sole trader or new business, a PSP can be a quicker route to accepting card payments. If you have CCJs, check each provider’s terms first.

This guide compares five UK card payment providers that suit businesses with poor credit in 2026. We’ve compared transaction fees, hardware costs, approval requirements, and what each provider says it checks during sign-up. Where a provider does not say whether it runs a credit search, we say so.

Square says no credit checks are required and Tide says its business account has no hard credit check. PayPal Point of Sale says it performs a credit check to verify identity, while SumUp and Revolut do not say. Every provider verifies identity before you can take payments.

Why Do Some Providers Run Credit Checks?

Traditional merchant account providers – think Worldpay, Barclaycard, and Elavon – issue each business a dedicated merchant account number. Because they’re taking on financial risk for each individual business (chargebacks, fraud, business failure), they underwrite every application carefully. That means a full credit check, often including a hard enquiry on your personal credit file, plus months of bank statements, proof of trading history, and sometimes a cash reserve.

The logic is simple: if your business folds mid-month and you’ve processed £20,000 in payments, the acquiring bank is exposed. Their credit check is how they assess that risk.

Traditional merchant account providers run credit checks because they’re financially exposed to each merchant’s chargebacks, fraud losses, and business failure risks.

Why PSPs Don’t Need to

Payment Service Providers operate differently. Rather than giving you a dedicated merchant account, they add you to a pooled merchant account they control. All merchants share the same merchant ID at the acquiring bank level. This means the PSP absorbs the risk collectively across its whole merchant base – no single business failure can wipe them out. The result: onboarding centres on identity and business verification, which providers carry out for anti-money laundering compliance, plus eligibility rules. Timing varies: Square says verification takes minutes, while SumUp says it typically takes 1-3 business days.

The trade-off is that PSPs charge slightly higher flat-rate transaction fees than a negotiated traditional merchant account might offer at high volume. For most small businesses processing under £10,000 per month, PSPs are still cheaper once you factor in the monthly fees and setup costs of traditional providers.

Best Card Machine Providers for Bad Credit 2026

The best card machine providers for bad credit in 2026 are Square, SumUp, PayPal POS, Tide, and Revolut – all applied for online, though credit-check policies differ (see the table).

Transaction fees checked against provider pricing pages between July and October 2026. Always verify current rates on the provider’s website before signing up.

In-person rate: 1.75%  |  Monthly fee: £0  |  Card reader: £19 + VAT  |  Contract: None

Square is the gold standard for businesses that want to start accepting payments without jumping through hoops. Square says you can start taking payments with no bank visits, credit checks or merchant accounts required, and that account creation and verification takes minutes. You will still need to verify your identity and provide business information.

The flat 1.75% transaction fee covers all UK debit and credit cards, Apple Pay, and Google Pay. The entry-level Square Reader (2nd generation) costs just £19 + VAT and pairs with your smartphone. For businesses needing a standalone POS terminal, Square Terminal costs £149 + VAT with a built-in receipt printer.

Where Square stands out is its ecosystem. The free plan includes a fully functional EPOS system, invoicing, payment links, an online store, and bookings – no other PSP on this list comes close for out-of-the-box functionality without a monthly fee. Funds settle the next working day to your bank account for free, or instantly for a 1.95% fee.

In-person rate: 1.69% (PAYG) or 0.99% (£19/month Payments Plus)  |  Monthly fee: £0 or £19  |  Card reader: From £25 + VAT  |  Contract: None

SumUp is particularly popular with sole traders, market stallholders, and service businesses that take payments on the move. Like Square, SumUp operates as a PSP. SumUp says all new users must verify their identity and business details before they can take payments, and that verification typically takes 1-3 business days. Its published verification guidance does not say whether it runs a credit search, so check before you apply if that matters to you.

The headline PAYG rate of 1.69% per transaction is slightly cheaper than Square’s 1.75%, and steps down to 0.99% if you take the Payments Plus subscription at £19/month. The entry-level SumUp Solo Lite costs £25 + VAT. For businesses needing a fully standalone device with built-in 4G SIM and receipt printer, the SumUp Terminal (£135 + VAT) is a strong option.

SumUp’s free business account offers next-day payouts by 7am (including weekends and bank holidays), which is faster than most competitors’ standard settlement. The 30-day money-back guarantee on hardware is a useful safety net for new businesses testing the water.

In-person rate: 1.75%  |  Monthly fee: £0  |  Card reader: £29 excl. VAT (first reader)  |  Contract: None

Formerly known as iZettle (acquired by PayPal for $2.2 billion in 2018), then Zettle by PayPal, and now branded PayPal Point of Sale, this is an established PSP. PayPal says your account must be approved before you can accept card payments, and that it performs a credit check to verify your identity and meet legal obligations. It does not say what type of check it runs or whether it shows on your credit file, so ask before you apply.

The PayPal Reader costs £29 excl. VAT for your first reader and charges 1.75% per in-person transaction – matching Square on rate, though its £29 + VAT reader costs more than Square’s £19 + VAT one. For businesses that also sell online, PayPal’s brand recognition delivers significant consumer trust: many customers feel more comfortable paying via PayPal than entering card details with an unfamiliar processor. Settlement lands near-instantly into your PayPal Business account, though transfers to your bank account take 1-3 business days.

Note: PayPal says your PayPal Point of Sale account must be approved before you can accept card payments.

In-person rate: 1.5% + 5p (PAYG)  |  Monthly fee: £0 (PAYG)  |  Card reader: £49 + VAT (PAYG)  |  Contract: None

Tide offers a competitive PAYG transaction rate at 1.5% + 5p per transaction, undercutting Square (1.75%) and roughly matching SumUp (1.69%) for businesses with moderate transaction volumes. Tide says there is no hard credit check when you open its business account, and you need that account to use the card reader, which is an important practical consideration. Tide’s Payment Links page applies a 90-day rule (90 days since you opened your Tide account); we could not find a published age rule for the card reader, so check the rules in the Tide app.

The Tide card reader costs more than Square’s entry model: the standard reader is £49 + VAT on pay as you go (£39 on the Essential plan, £29 on Premium) versus £19 for Square’s basic reader. However, it includes lifetime-free 4G connectivity – there are no ongoing SIM or data costs. The Tide Card Reader Plus (£69 + VAT on pay as you go) adds a built-in receipt printer and works as a standalone device without needing your smartphone.

Tide’s card reader is best suited to businesses already banking with Tide who want seamless integration between their payments and business account. A £200 cashback offer (for completing £1,500 in transactions within 90 days using code TCRPOS) partially offsets the higher hardware cost.

In-person rate: 0.8% + 2p (UK consumer cards)  |  Monthly fee: From £10/month  |  Card reader: £129 + VAT (Lite Terminal)  |  Contract: None

Revolut Business offers the lowest in-person transaction rates on this list – just 0.8% + 2p per transaction for UK consumer cards – but those rates come with a mandatory monthly subscription starting at £10/month for the Basic plan (£30/month for Grow, £90/month for Scale). Revolut says you need an active Revolut Business Merchant account to order its readers, and that to apply you must have a registered business in an eligible country. It does not publish whether it runs a credit search on that application.

At 0.8% + 2p, Revolut breaks even against SumUp’s 1.69% PAYG rate at roughly £1,100 per month in card turnover (before the 2p per-transaction fee), and costs less than SumUp’s Payments Plus plan (0.99%, £19/month) at any volume before that 2p fee, making it financially attractive for businesses processing more than that. The entry-level Revolut Lite Terminal costs £129 + VAT (the standalone Revolut Terminal is £169 + VAT). Settlement is within 24 hours.

Revolut Business requires an incorporated UK company. Sole traders cannot currently open a Revolut Business account, which limits its reach for the self-employed market.

What to Expect Instead of a Credit Check

Whether or not a provider runs a credit search, expect identity verification, business details, and confirmation you’re not operating in a restricted industry category.

Providers carry out compliance checks required by law, whether or not they also run a credit search. Understanding what they will check helps you prepare a smooth application:

Identity Verification (KYC)

All FCA-regulated payment providers must verify who you are under Anti-Money Laundering (AML) regulations. Expect to be asked for documents such as:

• A valid government-issued photo ID (passport or driving licence)
• Proof of address (utility bill, bank statement – usually within 3 months)
• Your National Insurance number or UTR (if a sole trader)
• Company registration number (if a limited company)

Business Eligibility Check

Each provider has a list of restricted or prohibited merchant categories. High-risk industries – including adult content, weapons, gambling, unregulated financial services, and certain pharmaceuticals – may be declined regardless of credit history. If you operate in a specialist or borderline category, check the provider’s acceptable use policy before applying.

Business Age Requirements

Some products carry minimum account-age rules: Tide’s Payment Links page requires 90 days since you opened your Tide account, and we found no published age rule for its card reader. Square, SumUp and PayPal POS did not publish a minimum trading history on the pages we checked, but all three verify applicants before you can take payments.

Transaction Volume Monitoring (Ongoing)

After onboarding, PSPs monitor your transaction patterns for fraud signals. Unusual spikes in volume, high refund rates, or elevated chargebacks can result in account holds or termination – even without a credit issue. Keeping your customers satisfied and dispute rates low is the most important ongoing compliance factor.

Pros and Cons of These Providers for Bad Credit

The providers in this guide offer quick online sign-up and simple flat-rate pricing, but charge higher transaction rates than negotiated traditional accounts at high processing volumes.

When You Might Need a Traditional Merchant Account

Traditional merchant accounts make financial sense for businesses processing over £30,000 per month, where interchange++ pricing typically undercuts PSP flat rates significantly.

A PSP is the right starting point for most small businesses – but there are scenarios where a traditional merchant account is worth the credit check:

High Transaction Volumes

Once your business is processing reliably above £20,000–£30,000 per month in card payments, the economics shift. Traditional providers offer interchange++ pricing, where you pay the actual interchange rate set by Visa and Mastercard plus a small processor margin – typically around 0.2–0.4% for most UK debit cards. At volume, this is substantially cheaper than a flat 1.75% from a PSP. At £30,000 per month, the difference between 1.75% and an effective interchange++ rate of ~0.6% is over £345 per month – enough to offset any monthly fee and justify the application process.

High-Risk or Specialist Industries

Some businesses – subscription services, travel, high-value goods, certain professional services – are refused by PSPs but can negotiate with specialist acquiring banks set up to handle their risk profile. A credit check is likely, but approval is possible with the right partner.

You Need a Dedicated MID

If you’ve experienced account holds with a PSP or need guaranteed payment processing stability (for example, you’re running a busy hospitality venue), a dedicated merchant account gives you your own Merchant ID and more control over chargebacks and disputes.

Predominantly Online or Card-Not-Present

Businesses with heavily online or manually keyed transaction volumes often find interchange++ pricing via a traditional provider materially cheaper than PSP card-not-present rates (Square charges 1.4% + £0.25 online versus 1.75% in-person).

How to Improve Your Chances of Approval

Businesses with poor credit can improve their PSP approval chances by ensuring their business registration is current, their industry category is compliant, and their ID documents are valid and up to date.

Whatever a provider’s credit-check policy, there are steps you can take to avoid a rejection:

1. Register your business correctly. Even as a sole trader, operating under a registered business name with HMRC demonstrates legitimacy. Limited companies should ensure Companies House records are current before applying.
2. Check your industry category. Before applying, review the provider’s acceptable use policy. If your business is adjacent to a restricted category, describe your activities carefully and accurately during sign-up.
3. Have ID documents ready. All providers require government-issued photo ID and proof of address dated within three months. Outdated or mismatched documents are a common cause of application delays.
4. Start with Square if your credit file is a concern. Square says no credit checks are required, whereas PayPal Point of Sale says it runs one to verify identity. If a provider declines you, ask why before applying elsewhere.
5. Build a short trading history first. If you’re brand new, even a few weeks of invoices, bank transactions, or a basic website adds credibility to your application and reduces the risk of automated rejection.
6. Avoid multiple simultaneous applications. Submitting applications to several providers at once and being rejected repeatedly may be recorded by each provider, and where a provider runs a credit search it may appear on your credit file.

Our Verdict

Square is our top pick for most businesses – no credit check, £19 reader, zero monthly fee, and the strongest free EPOS ecosystem of any PSP operating in the UK.

For the vast majority of UK small businesses with poor credit, no credit history, or simply no desire to go through a lengthy traditional merchant account application, Square is the clear recommendation. The £19 card reader, zero monthly fee, 1.75% flat rate, and best-in-class free EPOS ecosystem make it the most complete package – and Square says account creation and verification takes minutes with no credit checks required.

If you’re already banking with Tide and process a moderate volume, the 1.5% + 5p PAYG rate makes Tide’s card reader worth considering despite the higher hardware cost. For mobile sole traders, SumUp’s portable hardware range and 1.69% PAYG rate are a strong alternative – particularly if you want the Payments Plus plan at 0.99% to drop costs as turnover grows. Revolut Business is the best choice for incorporated companies processing higher volumes who can absorb the £10/month minimum subscription in exchange for the 0.8% + 2p rate. And PayPal POS earns its place for businesses that sell online as well as in-person, where PayPal’s brand recognition drives checkout conversion.

Credit-check policies differ. Square says no credit checks are required and Tide says its business account has no hard credit check. PayPal Point of Sale says it performs a credit check to verify your identity, and SumUp and Revolut do not say whether they run one, so ask before you apply if your credit file matters. Every provider verifies who you are and what you sell, and each can decline industries outside its acceptable use rules.
