9 Best Card Machines for Small Businesses in 2026

Why Card Machines Are Now Essential for UK Small Businesses

Cash payments now account for less than 10% of all UK transactions, down from nearly 60% a decade ago. Debit card payments alone made up more than half of all UK transactions in 2024 — over 26 billion individual payments — and the majority of these were contactless. For any small business, refusing or being unable to accept card payments means losing sales.

But choosing the right card machine is not simply a matter of picking the cheapest device. The wrong choice can lock you into an expensive contract, saddle you with high transaction fees, or leave you with equipment that doesn’t work where and how you trade. This guide reviews 9 of the best card payment machines available to UK small businesses in 2026, with pricing verified from official provider websites.

How Card Machine Pricing Works: What You Actually Pay

Every card machine involves at least three types of cost, and most providers bundle or obscure them in different ways:

• Hardware cost: Either a one-off purchase price (e.g. Square Reader at £19 + VAT) or an ongoing monthly rental. Rental seems cheaper upfront, but can cost significantly more over 12–18 months than buying outright.
• Transaction fees: A percentage of every payment you accept. UK rates range from around 0.8% to 1.99% for standard in-person payments with UK personal debit cards. International, corporate, and Amex cards typically attract higher rates.
• Monthly service/subscription fee: Some providers charge a fixed monthly fee (e.g. Tyl from £13.99/mo, SumUp Payments Plus at £19/mo). Others, like Square and PayPal Zettle, are genuinely free monthly with higher per-transaction rates.

The most important concept to understand is the break-even point between pay-as-you-go and subscription-based pricing. SumUp, for example, publishes this clearly: if you process more than £3,000 per month in card payments, their Payments Plus subscription (£19/month, 0.99% per transaction) saves money over the free plan (0% monthly, 1.69% per transaction). Below £3,000/month, the free plan is cheaper.

Run the same calculation for any provider before committing to a contract.

Which Type of Card Machine Is Right for Your Business?

There are three broad categories of card payment devices, and the right one depends on how and where you trade:

• Mobile card readers (Square Reader, SumUp Air, PayPal Zettle Reader and Tide Card Reader): compact devices that pair with your smartphone via Bluetooth or have a built-in SIM. Best for market traders, mobile tradespeople, pop-ups, and businesses that move between locations.
• Portable terminals (Dojo Go, Tyl PAX A920 Pro, Barclaycard Smartpay Touch): full-featured devices with touchscreens, built-in Wi-Fi and 4G, and long battery life. Best for restaurants, cafés, and retail businesses where staff take payments on the floor.
• Countertop terminals (Worldpay DX8000, Tyl PAX A80, Lightspeed): tethered to your till via Ethernet or Wi-Fi. Best for fixed-till environments like convenience stores, pharmacies, and busy retail environments.

The 9 Best Card Machines Reviewed

1. Square Reader (2nd Gen) – Best Overall for Startups

Device Cost	£19 + VAT (new customers); additional readers at standard pricing
In-Person Fee	1.75% per transaction (all UK cards, contactless and chip & PIN)
Online / Keyed-In Fee	1.4% + 25p (UK cards, online); 2.5% + 25p (non-UK cards); 2.5% (manually keyed)
Monthly Fee	£0 — pay as you go
Settlement	1–2 working days (free); instant transfer available for 1.5% fee
Contract	None
Connectivity	Bluetooth (pairs with iOS or Android smartphone)
Cards Accepted	Visa, Mastercard, Amex, Maestro, Visa Electron, V Pay

At £19 + VAT, the Square Reader is the most affordable entry point on this list and one of the most widely used card readers by UK small businesses. There is no monthly fee and no contract — you pay 1.75% per in-person transaction and nothing else for standard use.

The second-generation reader supports chip & PIN and contactless (including Apple Pay and Google Pay), and can process offline payments for up to 24 hours without an internet connection — useful for markets and events with weak signal, though Square notes that offline payments are not supported on all older reader versions, and declined payments cannot be recovered if the device doesn’t reconnect within the window.

Free software included with every Square account covers a full POS app, sales dashboard, customer directory, inventory management, invoicing, and fraud monitoring. Businesses processing more than £200,000 per year in card payments can contact Square to discuss custom rates.

Best for: Start-ups, first-time card payment users, market traders, pop-ups, and any business where zero monthly commitment is essential.

Watch out for: No built-in printer or customer-facing screen. The 1.75% rate is higher than subscription-based rivals at meaningful volumes. International cards attract an additional 1.5% fee on top of base rates.

2. Tide Card Reader – Best for Low Transaction Fees

Device Cost	Pay As You Go: £159 + VAT; Sell In-Person subscription: from £99 + VAT (or £0 with rental plan)
In-Person Fee (PAYG)	1.39% + 5p per transaction (domestic consumer debit cards)
In-Person Fee (Sell In-Person, buy)	0.79% + 3p per transaction (domestic consumer debit cards)
In-Person Fee (Sell In-Person, rental)	0.69% + 3p per transaction (domestic consumer debit cards)
Monthly Fee	PAYG: £0; Sell In-Person (buy): £12.99; Sell In-Person (rental): £24.99
Settlement	Up to 3 working days standard; next working day available for £2.99 + VAT/month
Contract	PAYG: none; Rental plan: 12-month minimum
Requirement	Tide business bank account required
Connectivity	Built-in 4G SIM (lifetime free) + Wi-Fi
Cards Accepted	Visa, Mastercard, Amex (UK or foreign issuers); all settlements in GBP
Exclusive Offer	Purchase your Tide Reader by 28/02/2026 using code TIDEZERO to get £200 cashback when you accept £1000 of payment using your Reader. You’ll also get 0% transaction fees on payments up to £10 for the first 3 months.

Tide Card Reader offers some of the lowest published transaction fees of any provider on this list, particularly for businesses that take out the Sell In-Person subscription. The rental plan at 0.69% + 3p is especially competitive for higher-volume traders — though it requires a Tide business bank account and a 12-month commitment.

The standard (PAYG) device costs £159 + VAT and includes a built-in 4G SIM with lifetime free data, removing the need for Bluetooth pairing with a smartphone. The Card Reader Plus (£199 + VAT) adds an integrated receipt printer. Tide also offers a Tap to Pay on iPhone option (no hardware needed) at 1.5% + 11p PAYG or 0.79% + 9p on subscription.

Note on settlement: unlike most rivals, standard Tide settlement takes up to three working days. Next-day settlement costs £2.99 + VAT per month as an add-on. If fast access to funds matters to your business, factor this into the true cost calculation.

Best for: Businesses that take regular card payments and want very low transaction fees, particularly if already banking with Tide.

Watch out for: Settlement is up to 3 working days as standard — slower than most competitors. Next-day settlement is an additional cost. Requires a Tide business account.

3. SumUp Air/ SumUp Solo – Best for Mobile Traders

Device Cost	Air: from £69 + VAT (standard; promotional pricing applies); Solo: from £69 + VAT with dock
In-Person Fee	PAYG: 1.69%; Payments Plus (£19/mo): 0.99% for UK/EEA domestic consumer cards
International/Amex Fee	1.69% (applies on both PAYG and Payments Plus plans)
Online / Payment Link Fee	2.5% per transaction
Monthly Fee	£0 (PAYG) or £19 (Payments Plus — annual plan saves 17%)
Settlement	By 7am next day (including weekends) via free SumUp Business Account; 1–2 days to external bank
Contract	None — cancel anytime; 30-day money-back guarantee on hardware
Connectivity	Air: Bluetooth + Wi-Fi; Solo: standalone with built-in touchscreen

SumUp is one of the most popular card reader providers among UK mobile traders and market stallholders. The Payments Plus subscription at £19/month reduces in-person fees to 0.99% for UK and EEA consumer cards — SumUp publishes this clearly on its pricing page: businesses processing more than £3,000 per month in card payments will save money on the subscription versus pay-as-you-go.

The SumUp Solo is a standalone device with a built-in touchscreen, removing the need to pair with a smartphone. Both models support Visa, Mastercard, Maestro, Amex, Apple Pay, Google Pay, and a wide range of international and alternative payment methods. All devices come with a full-day battery and SumUp’s locked-fee guarantee — rates will not change for the life of your plan.

Best for: Mobile beauty therapists, market stallholders, food van operators, and sole traders wanting simple, contract-free payments with a clear fee lock.

Watch out for: SumUp’s advertised device prices change frequently with promotions. Always check sumup.com/en-gb/pricing/ for current hardware pricing before ordering.

4. Lightspeed – Best for Established Retailers and Hospitality with Full POS Needs

Device Cost	Hardware quoted on request (iPad-based or dedicated terminal options)
In-Person Fee	1.5% (UK card-present transactions via Lightspeed Payments)
Contract	Requires active Lightspeed POS subscription (from £69+/month for retail; custom for restaurant)
Settlement	Next working day
Connectivity	Wi-Fi; EPOS integrations available
POS Plans	Retail: Basic, Core, Plus — contact Lightspeed for UK pricing; Restaurant: quote required
Support	24/7 dedicated support included with all plans

Lightspeed is a full commerce platform rather than a standalone card reader — it combines POS software, inventory management, reporting, and integrated payments in a single system. Lightspeed Payments in the UK charges 1.5% for card-present transactions, according to its published UK content, making it competitive for in-person payments where high average transaction values are common.

Lightspeed is genuinely suited to businesses that need professional-grade inventory management, multilocation support, and deep EPOS integration: it supports over 8 million pre-loaded product items, advanced employee performance reporting, and both retail and hospitality-specific workflows. The 24/7 support model is a material advantage for businesses that can’t afford system downtime.

However, Lightspeed is not a lightweight solution. Hardware pricing is not published online — you’ll need to contact sales for a quote. Plans require a monthly subscription (from £69/month in some markets), and Lightspeed’s UK pricing page directs businesses to contact sales for a personalised quote. This is appropriate for established businesses but is not cost-effective for low-volume or early-stage traders.

Best for: Established retail shops, boutiques, restaurants, and multilocation businesses that need a unified POS, inventory, and payment system. Not suitable for low-volume or casual traders.

Watch out for: UK-specific pricing is not published in full — contact Lightspeed directly. Monthly subscription costs add to the total cost of card acceptance. Hardware is not sold off-the-shelf.

5. PayPal Zettle (Now PayPal Point of Sale) – Best for Existing PayPal Users

Device Cost	Reader: £29 + VAT (new business users, 1 per customer); additional readers £69 + VAT. Terminal: £149 + VAT
In-Person Fee	1.75% per transaction — same rate for all major cards including Amex
Online Fee	1.75% (same flat rate regardless of payment type)
Monthly Fee	£0 — no monthly or setup fees
Settlement	Typically within minutes to PayPal Business balance; bank transfers at no extra fee
Contract	None
Connectivity	Reader: Bluetooth (pairs with iOS or Android via PayPal POS app); Wi-Fi via Terminal
Battery	Reader: up to 8 hours / approx. 100 transactions
Cards Accepted	Visa, Mastercard, Amex, Maestro — same rate for all

PayPal Zettle — now rebranded as PayPal Point of Sale in the UK — offers a genuinely simple pricing model: one flat rate of 1.75% for all in-person card transactions, regardless of card type. There is no extra charge for Amex, no monthly fee, and no contract.

At £29 + VAT for new business users, the Reader is one of the most affordable devices on this list, and funds settle to your PayPal Business account within minutes. The POS app is free and includes sales reporting, inventory management, and product catalogues. The Terminal (£149 + VAT) adds Wi-Fi connectivity and a built-in receipt printer in one device.

The main limitation is battery life: the Reader lasts approximately 100 transactions per charge — significantly lower than SumUp’s full-day battery. For high-volume trading days or events, plan for recharging or carry a backup power bank.

Best for: Businesses already using PayPal for online payments, market traders, and anyone wanting a single flat rate across all card types with no monthly commitment.

Watch out for: Reader battery lasts roughly 100 transactions — plan for busy days. Settlement to an external bank follows PayPal’s standard transfer schedule rather than being immediate.

6. Worldpay 360 (DX8000) – Best for Established Businesses Needing Full-Service Acquiring

Device	Worldpay DX8000 mobile card machine (Wi-Fi + 4G)
Device Cost	£1/month for first 12 months (special offer); then £15/month — 18-month hire agreement
In-Person Fee (Simplicity)	1.5% per transaction (Mastercard and Visa UK cards); single flat rate, no authorisation fee
In-Person Fee (Custom)	Variable pricing — for businesses taking over £75,000 in annual card turnover
Monthly Fee	£15/month terminal hire (£1/month for 12 months with current offer)
No Joining Fee	£0
Settlement	Next working day (free)
Contract	18-month minimum hire agreement
Eligibility (Custom)	Annual card turnover over £75,000
Support	24/7 UK support; next-day terminal replacement standard

Worldpay is the UK’s largest card payment processor, and the DX8000 is its mobile terminal for small and medium businesses. The Simplicity pricing plan offers a single flat rate of 1.5% per Mastercard and Visa transaction with no authorisation fee and no minimum monthly service charge — making it straightforward to calculate costs. The special offer of £1/month for the first 12 months reduces the upfront commitment significantly.

Custom pricing is available for businesses processing more than £75,000 per year in card turnover, and variable rates on debit cards can be substantially lower than the Simplicity flat rate at higher volumes. Worldpay’s next-day terminal replacement service is a meaningful practical advantage for businesses that cannot afford downtime — something that fintech-only providers typically cannot match.

The 18-month contract is the key trade-off. For a business with stable, predictable card volumes, this is manageable. For a seasonal or early-stage business, the commitment may be risky if trading patterns change.

Best for: Established businesses with consistent monthly card volumes who want professional-grade hardware, next-day replacement, and the security of working with the UK’s largest processor.

Watch out for: 18-month contract. Custom pricing is only unlocked at £75k+ annual turnover. The Simplicity plan’s 1.5% applies to Mastercard and Visa — different fees apply for Amex, Diners, Discover, JCB, and other card types.

7. Tyl by NatWest – Best for High-Street Businesses Wanting Bank-Backed Acquiring

Device Cost	From £13.99 + VAT/month (PAX A80 countertop rental); PAX A920 Pro from £19.99 + VAT/month
In-Person Fee	1.39% + 5p (UK & European personal cards — debit or credit from a private account)
Other Card Fee	1.99% + 5p (all other cards, including business cards and non-EU international)
CNP / Online Fee	Same rate — Tyl does not charge extra for card-not-present or online payments
Monthly Fee	Card machine rental from £13.99 + VAT/month; online payment gateway £14.95 + VAT/month
PCI Compliance	From £4 + VAT/month for some businesses (check your quote)
Settlement	Next working day
Contract	12-month minimum; no cancellation fee
Connectivity	PAX A80: Wi-Fi/Ethernet; PAX A920 Pro: Wi-Fi/4G
Eligibility	Business must be based and trading in the UK; applicant must be 18+

Tyl by NatWest is backed by NatWest Bank and offers transparent, published pricing that is genuinely competitive. The 1.39% + 5p rate for UK and EEA personal card payments is cheaper than Square (1.75%), and SumUp PAYG (1.69%), and Tyl notably charges the same fee for in-person, online, and phone transactions — a rarity in the industry.

There is no minimum monthly service charge, and Tyl’s pricing page explicitly confirms no extra fees for card-not-present payments, international card payments, or refunds. The Tyl Portal provides free access to real-time sales reporting and analytics. The PAX A920 Pro supports Tap to Pay on iPhone at no additional hardware cost.

The 12-month contract is the main trade-off: while there is no cancellation fee, you’re committed to renting the terminal for the contract duration. Some businesses will also be charged a PCI compliance fee of £4 + VAT/month, depending on volume — ask Tyl directly whether this applies to your account.

Best for: High-street retailers, service businesses, and SMEs wanting bank-level security, transparent pricing, and the same rate across all payment channels.

Watch out for: 12-month rental commitment. PCI compliance fee may apply. A NatWest business account is not required, but you must be a registered UK business.

8. Dojo Go – Best for Hospitality and High-Volume Retail

Device Cost	Fix plan: included in £39.99/month flat fee; Upfront option: from £79
Dojo Go Monthly (Fix)	£39.99/month — covers transactions up to £3,999 card turnover/month; bespoke above
Dojo Go Monthly (Flex)	From £20/month — custom transaction rates; suitable for higher-volume businesses
Transaction Fees	Fix: flat monthly fee up to limit; Flex: custom (debit, credit, and secure transaction rates)
Secure Transaction Fee	£0.05 per authorisation (applies on Flex and contract plans)
Refund Fee	£0.50 per transaction
Settlement	Next working day by 10am (7-day settlement upgrade available for weekends and bank holidays)
Contract	12-month (then monthly rolling); 30-day exit available within first 30 days of sign-up
EPOS Integrations	600+ EPOS systems
Exit Fee Support	Dojo may cover exit fees up to £3,000 if switching from another provider (eligibility applies)

Dojo serves more than 110,000 UK businesses and is particularly well established in hospitality and retail. The Fix plan offers unusual simplicity: one flat monthly fee of £39.99 covers all transactions up to £3,999 per month in card turnover, with no per-transaction percentage — suitable for smaller businesses that want a predictable monthly cost. The Flex plan offers custom rates for growing businesses.

Settlement by 10 am the next working day is standard, with a 7-day upgrade available that extends this to weekends and bank holidays. The Dojo Go itself has been measured at 58% faster transaction speeds than the market average in independent testing, and supports tip management, bill splitting, and Pay at Table — features that make it particularly effective in food service.

The 12-month contract is standard, though Dojo offers a 30-day no-exit-fee window on sign-up. For businesses switching from another provider, Dojo may cover exit fees up to £3,000, subject to your annual card turnover — currently extended to businesses taking up to £150,000 in annual card turnover.

Best for: Cafés, restaurants, bars, and busy retail businesses that want fast settlement, EPOS integration, and purpose-built hospitality features like tipping, bill splitting, and Pay at Table.

Watch out for: Transaction fees are not fully transparent without requesting a quote. A £0.50 refund fee and £0.05 secure transaction fee apply to some plans. 12-month contract required.

9. Barclaycard Smartpay Anywhere – Best for App-Based POS with Tailored Pricing

Device Cost	Custom pricing — requires application and vetting (for businesses taking under £100k/year)
Transaction Fee	Tailored on application; example rate on Barclaycard’s own site: 0.7% + 3p authorisation fee
Monthly Fee	Variable — part of tailored pricing plan
Settlement	Next working day (for transactions taken before 7pm)
Contract	Rolling — no long-term contract required for Smartpay Anywhere
Connectivity	Bluetooth (connects via Smartpay Anywhere app on iOS or Android)
Cards Accepted	Visa, Mastercard, Amex, Diners Club, Discover, UnionPay, JCB; Apple Pay, Google Pay
Accounting Integration	Available via Smartpay Anywhere app portal

Barclaycard Smartpay Anywhere offers tailored transaction fees rather than a published flat rate — an application process is required, during which Barclaycard assesses your business’s financial history and expected turnover. The example rate shown on Barclaycard’s pricing page (0.7% + 3p authorisation fee) is illustrative and representative rather than the price you will receive.

The Smartpay Anywhere app functions as a lightweight POS with product listings, sales reporting, and accountancy software integration. There is no long-term contract for Smartpay Anywhere specifically. Settlement is the next working day for transactions taken before 7 pm — note that for the Smartpay Touch terminal, this also applies to the 7 pm cut-off.

Barclaycard’s breadth of accepted card types is notable: Visa, Mastercard, Amex, Diners Club, Discover, UnionPay, and JCB are all accepted alongside Apple Pay and Google Pay. For businesses with international customers paying with less common card types, this range is a genuine advantage.

Best for: Small hospitality and retail businesses wanting customised transaction rates, a broad range of accepted card types, and a Barclays-backed provider without a long-term contract.

Watch out for: Pricing requires application and is tailored individually — you cannot compare rates until you apply. Additional fees (minimal monthly service charge, PCI DSS fees, chargeback fees) may apply — ask for a full fee schedule before committing.

How to Choose the Right Card Machine for Your Business

Beyond the numbers in the comparison table, these are the practical factors that most commonly catch small business owners out:

• Volume threshold: Calculate your typical monthly card turnover. If you regularly process more than £2,000–£3,000/month, a subscription or contract-based model with lower per-transaction rates will almost always be cheaper than PAYG — regardless of which provider you choose.
• Settlement speed: Standard settlement ranges from minutes (PayPal, to PayPal balance) to three working days (Tide, standard). If daily operational cash flow is tight — as it is for most hospitality businesses — this is a critical consideration, not an afterthought.
• Contract risk: Worldpay, Dojo, and Tyl all require contracts of 12–18 months. If your business is seasonal, growing rapidly, or still finding its model, pay-as-you-go (Square, SumUp, PayPal) preserves flexibility.
• Connectivity where you trade: Bluetooth readers (Square, PayPal, Barclaycard Smartpay) depend on your smartphone’s data connection. Built-in SIM devices (Tide, Dojo Go) work independently. For outdoor markets, festivals, or rural locations, a built-in SIM is a meaningful advantage.
• Hardware replacement: If your terminal breaks during a busy service, how quickly can you get a replacement? Worldpay advertises a next-day terminal replacement service. Most fintech providers offer hardware support via app or email, which can mean slower response times in an emergency.
• EPOS integration: If you already use an EPOS system, check compatibility before choosing a card machine. Dojo integrates with over 600 EPOS systems. Lightspeed has a native payments integration. Square works with a range of third-party partners. Barclaycard integrates with some accounting software via its portal.

Common Mistakes When Choosing a Card Machine

These are the errors that cost UK small businesses money:

• Comparing headline rates without calculating volume: A 1.75% rate sounds affordable, but on £20,000/month in card sales, it costs £350/month in transaction fees. A 1.39% rate on a £13.99/month rental plan costs £293 in combined fees on the same volume — saving over £600 per year.
• Assuming all settlement is next-day: It isn’t. Tide’s standard settlement takes up to three working days. Shopify WisePad 3 takes three working days. PayPal settles to your PayPal balance within minutes but to your bank on a separate schedule. Always ask specifically: how long to my business bank account?
• Ignoring card-not-present fees: If you ever take payments by phone, payment link, or online, the CNP fee is different from the in-person rate for most providers — and is often not on the homepage. Tyl is unusual in charging the same rate regardless. Confirm the CNP fee before signing up.
• Not asking about PCI compliance fees: Several providers charge separately for PCI DSS compliance — typically £4–£5/month. These are often not mentioned in the headline pricing and only appear in the detailed terms or on request.
• Over-buying hardware for a new business: A £149 terminal or full POS system is not necessary to start taking card payments. A £19–£29 mobile reader is sufficient for most new traders, and upgrading later is always an option.

Business Card Machine FAQs

Our Verdict

There is no universal best card machine. The right choice depends on how much you sell, where you trade, how quickly you need funds, and how long you can commit to a provider. Use this decision guide:

• Just starting out: Square Reader — £19 + VAT, no contract, no monthly fee, works immediately.
• Mobile trading (markets, events, trade): SumUp Solo or Tide Card Reader (for built-in 4G and lowest fees at volume).
• Café, bar, or restaurant: Dojo Go — fast settlement, bill splitting, tipping, 600+ EPOS integrations.
• High-street retail with bank backing: Tyl by NatWest — competitive rates, same fee for all channels, NatWest-backed security.
• Existing PayPal user: PayPal Zettle Reader — fast settlement to PayPal balance, one flat rate including Amex.
• Large established business: Worldpay — custom rates, next-day replacement, UK’s largest processor.
• Full POS with inventory management: Lightspeed — not the cheapest entry point, but the most capable platform for established retailers.
• Tailored pricing without la ong-term contract: Barclaycard Smartpay Anywhere — application required, but rolling terms and a wide range of accepted cards.
