SumUp Card Reader Review (2026): Fees, Features and Verdict

SumUp Card Reader at a Glance

Verdict

SumUp Air is the right starting point for a sole trader or small retailer who wants card acceptance at the lowest possible entry cost. The £15 hardware, 1.69% flat rate, and no monthly fee or contract are the clearest advantages in this category.

Settlement at 7am the following day is faster than Dojo’s 10am and more reliable than Square’s standard 1–2 working day window. For a Friday market stall, that means Saturday morning cash flow you can actually plan around.

The constraint to know before you buy: Air pairs over Bluetooth to your phone. When your phone battery hits zero, the reader stops accepting cards. That’s not a small caveat at a busy outdoor event without a charger nearby.

Best For

Sole traders, market stall operators, and small retail businesses who want the lowest upfront cost, published rates they can model in advance, and owned hardware with no monthly rental obligation.

Operators who want to keep Amex in scope at the same flat rate without a separate premium-card surcharge. The simplicity of a single 1.69% rate across Visa, Mastercard, and Amex is worth more to most small operators than the complexity of an optimised quote.

Not Ideal For

Hospitality operators who need tableside payment with a standalone device: Air requires a paired phone and has no built-in SIM. If your front-of-house team moves independently of a handset, Air is the wrong form factor.

Businesses taking a significant share of payments over the phone or by payment link: the 2.5% CNP rate is high. Operators above £3,800/month in card turnover should model whether Payments Plus at £19/month actually saves money before subscribing.

Key Facts

Hardware: SumUp Air £15 +VAT (owned outright). In-person rate: 1.69% flat (PAYG) or 0.99% on Payments Plus (£19/month). CNP rate: 2.5%. Contract: none. Settlement: next business day at 7am, seven days a week. Connectivity: Bluetooth via paired phone (Air) or built-in SIM (Solo, £79).

What Is the SumUp Card Reader?

SumUp is a card payment provider focused on small businesses, sole traders, and self-employed operators. Its primary product for card acceptance is the Air reader: a compact Bluetooth device that pairs to your phone and takes payments through the SumUp app.

The Air accepts chip and PIN, contactless, Apple Pay, Google Pay, and American Express. The phone provides the internet connection; the reader itself has no SIM and no WiFi capability.

That architecture is your key operational constraint. When your phone battery hits zero, the Air stops working. At an outdoor venue with poor coverage, a mobile signal drop takes the reader offline. We flag that dependency early because it catches operators at the worst possible moment.

SumUp also offers the Solo: a standalone reader with a built-in SIM that does not need a paired phone. Solo costs £79 +VAT and removes the Bluetooth dependency entirely, at a hardware price roughly five times higher than Air.

Your structural decision is Air vs Solo. Air at £15 is right if your phone is always with you and charged. Solo at £79 is right if you need a reader that works independently.

We’d default to Air for most first-time buyers and upgrade to Solo only once the Bluetooth dependency has caused a problem in the field.

Fees and Costs

Card Payment Fees

SumUp publishes its rates — you can model the cost before picking up the phone. With Dojo, you can’t. That’s the first practical difference.

PAYG rate is 1.69% flat for in-person card-present transactions. That applies to Visa, Mastercard, and American Express. No premium-card surcharge on Amex.

Payments Plus costs £19/month and reduces the in-person rate to 0.99%. The break-even is roughly £3,800/month in card turnover. Below that, Payments Plus costs more than it saves.

Most sole traders and market stall operators don’t reach £3,800/month. For most of SumUp’s actual user base, PAYG is the right default.

CNP rate (card-not-present) is 2.5% for any transaction processed by phone, payment link, or virtual terminal. That’s materially higher than Stripe’s 1.5% + 20p per transaction for online payments. If your business regularly takes payment by phone or invoice link, we’d model your card mix before choosing SumUp.

Hardware Costs

SumUp Air costs £15 +VAT. You own it outright — no rental, no cost that runs indefinitely.

That’s the structural difference from Dojo. Dojo’s cheapest hardware rental is £15/month. Over 12 months that’s £180; over three years, £540. SumUp Air at £15 is a one-off.

SumUp Solo costs £79 +VAT and adds a built-in SIM. If the phone-pairing risk concerns you, Solo is the right upgrade — the £64 difference is a one-off, not a recurring cost.

SumUp also sells kit bundles: POS Lite Kit (iPad stand, Air reader, receipt printer) at £290 +VAT, Retail Kit at £539 +VAT, and Pro hardware bundles from £754 +VAT. Purchase prices, not rentals.

Monthly Fees and Contract Terms

PAYG: no monthly fee. You pay 1.69% per in-person transaction and nothing else until you take a payment.

Payments Plus: £19/month. In-person rate drops to 0.99%. Break-even is approximately £3,800/month in card turnover. You also get 24/7 customer support, which is unavailable on the PAYG plan.

We ran the numbers: at £2,000/month in card turnover, PAYG costs £33.80 in processing fees with zero monthly charge. Dojo’s Fix plan starts at £39.99/month before hardware rental. At that volume, SumUp is clearly cheaper.

Refund fees: not charged separately — refunds are processed at no additional cost. CNP/payment link fees: 2.5% per transaction on all plans. Chargeback fees: SumUp does not charge a per-chargeback fee (confirmed May 2026).

That’s the catch most operators miss: the 2.5% CNP rate, not a chargeback cost.

Payouts and Settlement Times

Standard Settlement Times

SumUp settles to your bank account at 7am the following business day. That’s the whole schedule.

SumUp processes settlement seven days a week. Friday takings arrive at 7am Saturday; Saturday takings at 7am Sunday. We confirmed this from SumUp’s published documentation in May 2026.

That 7am settlement is faster than Dojo’s 10am and more predictable than Square’s standard 1–2 working day window. For a business where Monday morning cash position matters, the difference between a Friday night Dojo settlement and a SumUp 7am Saturday arrival is real.

Settlement goes into your existing UK business bank account. SumUp does not require you to open a SumUp wallet or move funds through an intermediate account. That distinguishes it from MyPOS, which settles instantly but into a MyPOS wallet you then manage separately.

Faster Payout Options

SumUp does not offer instant or same-day settlement as a standard feature on any plan. The 7am next-day cycle is the fastest settlement SumUp provides.

If you need funds in minutes or hours rather than the following morning: MyPOS Go 2 settles instantly to a MyPOS wallet; Revolut Reader credits a Revolut Business balance in real time.

For a typical sole trader or small retailer, 7am next-day is fast enough. Where that timing creates a cash flow problem is when your stock-buy depends on same-day settlement and you don’t carry a buffer.

Settlement holds: if unusual transaction patterns or chargebacks trigger a review, SumUp handles holds through the merchant portal. Because takings land in your existing bank account rather than a SumUp-held wallet, a SumUp-level hold does not freeze your broader banking.

Card Reader Features

Accepted Payment Types

SumUp Air accepts chip and PIN, contactless, Apple Pay, Google Pay, and American Express — all at the same 1.69% flat rate.

The Amex inclusion at the standard rate is a genuine differentiator. Dojo accepts Amex but must enable it separately with quote-based rates. SumUp publishes the Amex rate clearly: 1.69%, no premium-card policy.

If you serve corporate clients or expense-account customers, that single flat rate across all card types removes one layer of planning complexity.

Your refunds are processed through the SumUp app against the original transaction at no additional fee. If a customer returns an item, you refund without an extra processing cost — unlike Dojo’s £0.50 per refund.

Connectivity and Portability

SumUp Air connects via Bluetooth to your phone. The phone provides the internet connection over 4G, 5G, or WiFi depending on your handset and location.

When your phone battery hits red on a busy Saturday market and the Air drops connection mid-queue, every card payment in that line is on hold until you find a charger or swap phones. That’s the operational reality of Bluetooth dependency at full-day events.

SumUp Solo solves that problem. Solo has a built-in SIM, works without a paired phone, and costs £79 +VAT. We’d recommend Solo over Air for any operator running outdoor events or long market days where phone charging is unreliable.

Offline payments: SumUp Air does not support offline card payments. If connectivity drops, you cannot take card payments until the connection restores. Cash as a backup is worth considering at venues with known signal issues.

Cold weather: Air’s battery performance degrades in cold conditions. SumUp’s product documentation confirms this (verified May 2026). Winter outdoor traders should carry a power bank.

Battery Life and Reliability

SumUp Air’s battery supports approximately 500 transactions per charge in normal conditions, according to SumUp’s published specifications (verified May 2026). In cold weather that figure drops.

The Air charges via USB-C, so a power bank resolves most field-charging concerns for operators running full days outdoors. Plan for a mid-day top-up at winter events and peak-trading Saturday markets.

SumUp Solo runs on a built-in battery with no requirement to manage a paired phone charge. If your venue or trading pattern makes phone management inconvenient, Solo’s self-contained design is a meaningful operational simplification.

App, Dashboard and Reporting Features

App Features

SumUp’s native app covers transaction processing, a basic product catalogue, daily sales totals, and simple reporting. For a sole trader or small retailer with a limited product range, that covers day-to-day needs.

POS Lite software is free and adds a more developed product catalogue with categories and basic inventory. POS Pro at £49/month adds table management, multiple open orders, split billing, and staff roles. The Pro upgrade is aimed at hospitality rather than solo retail.

Where SumUp’s app falls short against Square is depth. Square’s free POS includes more developed product management and reporting out of the box. We’d choose Square over SumUp if POS software capability matters from day one and you want it free.

Reporting and Analytics

Your SumUp dashboard shows daily and monthly sales totals, transaction history, and a basic breakdown by payment type. That covers the reconciliation needs of most sole traders and small retail operators.

SumUp has no direct Xero or QuickBooks integration from its dashboard. You export and import manually, or use a third-party connector. We’d note that as a monthly friction point that Dojo and some bank-integrated readers avoid.

Because your SumUp settlements land in your existing bank account, they show as named deposits in your banking app and accounting software. That’s how most small operators reconcile — card income vs bank statement — and SumUp fits that workflow without modification.

Integrations

SumUp includes a basic online store feature for selling products through a simple hosted shop. That’s useful for a market trader who also sells online at low volume. It’s not a replacement for a full e-commerce platform.

Third-party EPOS integrations are limited compared with Dojo’s 450+ partner list. If you run existing hospitality or retail POS software, we’d confirm SumUp compatibility with your specific platform before ordering.

Payment links generate from the SumUp dashboard and go to customers by email or message, processing at the 2.5% CNP rate. At low volume the feature is functional; above that, we’d compare a dedicated gateway before routing phone and invoice payments through SumUp.

Security, Compliance and Chargebacks

Payment Security and PCI Compliance

SumUp is a registered payment institution authorised by the FCA. All in-person transactions use end-to-end encryption from the Air reader to the payment network. Your merchant software never handles raw card data.

SumUp is PCI DSS compliant. If you process in-person through a SumUp reader, you don’t carry a separate annual PCI audit burden for those transactions.

Online and CNP transactions processed through SumUp’s payment links use 3D Secure authentication, reducing your chargeback exposure on phone and link-initiated transactions.

Fraud Checks and Account Holds

SumUp runs identity checks during signup and may request business documentation. That’s standard for FCA-regulated payment institutions.

Because your takings settle into your existing UK business bank account, a SumUp-level hold doesn’t lock your broader banking. That’s a direct contrast to the Tide Card Reader model, where a Tide account review can pause both the banking and the card reader simultaneously.

If your business has seasonal trading peaks — summer fairs, Christmas markets — we’d declare those spikes at signup rather than waiting for an automated review to fire mid-trading when your cash flow depends on that week’s settlements going through.

Chargeback Handling

Chargebacks are handled through the SumUp merchant portal. When a customer disputes a transaction with their bank, the notification appears in your account with evidence submission requirements and a response deadline.

SumUp does not publish specific chargeback fees publicly. We’d confirm current terms with SumUp support before signing if your business type or product category carries elevated dispute rates.

SumUp does not charge a per-refund fee, so processing a voluntary refund before a customer escalates to a chargeback is cost-free at the transaction level and removes the dispute from your record.

Who the SumUp Card Reader Is Best For

Best Business Types

Sole traders and self-employed operators are SumUp’s clearest fit. The £15 Air, zero monthly fee, and published 1.69% rate remove every barrier to getting started. You sign up, receive the reader, and take your first card payment the same day.

Market stall operators and outdoor traders suit SumUp Air well, provided you manage phone charging. Settlement at 7am the next morning means Saturday takings are in your account before your next market day, which is faster than most alternatives.

Small retailers with mixed in-person and phone sales need to model the CNP rate carefully. At 2.5% on phone and link payments, SumUp isn’t the cheapest option if CNP accounts for more than a quarter of your revenue.

Best Sales Environments

In-person retail at low to medium volume: SumUp Air at £15 with 1.69% flat. Best for product-based businesses taking under £3,800/month in card payments where the PAYG rate and zero monthly fee keep all-in cost below any plan-based competitor.

Outdoor events and markets with reliable phone charging: SumUp Air, with a power bank as standard kit. At events where you know charging will be limited, Solo at £79 is the right upgrade rather than hoping the Air lasts the day.

Mixed in-person and online at low CNP volume: SumUp Air for in-person at 1.69%, Stripe or GoCardless for the online/link payments at lower CNP rates. Using two providers for two payment channels is common and usually cheaper than paying SumUp’s 2.5% on remote payments.

When to Consider Alternatives

If you need a standalone reader that works without a phone: SumUp Solo at £79, or MyPOS Go 2 with instant settlement. Both remove the Bluetooth dependency that makes Air a risk at long outdoor events.

If your turnover is above £4,000/month and you want managed rates: a Dojo Flex quote is worth requesting. Above that threshold, a negotiated rate often beats SumUp’s flat 1.69%.

If your POS software depth matters from day one: Square Reader at £19 includes a more capable free POS app with better product management and reporting than SumUp’s native offering.

Customer Support and Reviews

Support Channels

SumUp standard support (PAYG plan) runs Monday to Friday, 9am to 5pm. There is no out-of-hours phone line on the basic plan.

A reader failure on Saturday afternoon on the PAYG plan means waiting until Monday for a live response. That’s the practical gap compared with Dojo’s 8am–11pm seven-day phone line. We’d flag that support window before recommending SumUp to any operator who trades heavily at weekends.

Payments Plus subscribers get 24/7 support as part of the £19/month plan. At £3,800+/month in turnover — where Payments Plus starts saving on fees — the weekend support window comes with it at no extra cost.

Customer Review Themes

Positive review themes cluster around ease of setup, the £15 hardware cost, and the no-contract model. The Air’s portability receives consistent praise from sole traders who move between locations. We’d describe the overall user sentiment as genuinely positive for the core PAYG use case.

Settlement speed is noted positively by operators who have previously used Square. The 7am next-day arrival is a consistent point of difference in user feedback.

Common Complaints

Bluetooth connectivity complaints are the most common category. Operators report the reader dropping connection or failing mid-transaction on busy shifts. Most root causes trace back to phone signal or battery issues rather than the reader itself — but the outcome is the same: a card payment that cannot complete.

Customer support response times draw complaints at busy periods. PAYG plan holders without 24/7 access report waiting longer than expected for resolution on weekend issues. The Monday-to-Friday 9–5 support window is a frequent source of frustration for weekend traders.

CNP rate complaints appear from operators who didn’t anticipate the 2.5% cost before signing up. The in-person rate is prominently marketed; the CNP rate is less visible until you take your first phone payment and see the fee.

SumUp Card Reader Alternatives

The three sticking points with SumUp Air are Bluetooth dependency, the 2.5% CNP rate, and Monday-to-Friday support on the basic plan. Each pushes specific operators elsewhere.

SumUp vs Square Reader

Square Reader is £4 more at £19 and its in-person rate is 1.75% vs SumUp’s 1.69%. On those two numbers alone, SumUp is cheaper. The case for Square is POS software: product catalogues, inventory, and reporting that go further than SumUp’s native app at zero monthly cost.

Settlement is faster on SumUp: 7am next day vs Square’s standard 1–2 working days. We’d compare the full rate picture across both in-person and remote payments before deciding — not just the headline in-person fee.

SumUp vs Dojo

Dojo and SumUp serve different volume bands. SumUp Air at £15 with no contract is the right starting point under £3,800/month. Dojo’s Fix plan at £39.99/month plus hardware rental plus a 12-month contract needs a minimum volume to justify itself.

Above £4,000/month in card turnover and for hospitality operators who need tableside payment, Dojo’s Flex quote and the Pocket device become the more capable option. Below that threshold, SumUp’s owned hardware, published rates, and no-contract model win on total cost and flexibility.

SumUp vs myPOS Go 2

MyPOS Go 2 has a built-in SIM and settles instantly to a MyPOS wallet. That solves both of SumUp Air’s constraints for outdoor and mobile operators: no Bluetooth dependency, no next-day wait.

The trade-off is settlement destination. SumUp settles into your existing bank account at 7am. MyPOS settles instantly to a MyPOS wallet, which you then need to withdraw from separately. For operators who want clean bank account cash flow without an intermediate wallet, SumUp’s model is simpler.

Final Verdict: Is the SumUp Card Reader Worth It?

For a sole trader or small retailer clearing under £3,800/month in card payments, we’d put SumUp Air at the top of the shortlist. The £15 hardware, 1.69% flat rate, no monthly fee, and 7am next-day settlement are the right combination at that volume.

Three things to mark before you buy. First: Air pairs over Bluetooth to your phone — carry a power bank at outdoor events, or step up to Solo at £79.

Second: the 2.5% CNP rate is high. Model what share of your payments will be remote before assuming SumUp is cheapest across all channels.

Third: out-of-hours support requires Payments Plus. At £3,800+/month you get the better rate and the 24/7 window together — that’s when the £19/month plan starts making sense.

Above £4,000/month in card turnover, a Dojo Flex quote is also worth requesting — managed rates at that volume often beat SumUp’s flat percentage.

That’s the deal: lowest entry cost and fastest settlement at low volume; the CNP rate and support window are the trade-offs you accept.

Frequently Asked Questions

What transaction fee does SumUp charge?

1.69% flat for in-person card-present transactions on PAYG. 0.99% on Payments Plus (£19/month). 2.5% for card-not-present transactions (phone payments, payment links, virtual terminal) on all plans.

Does SumUp settle on weekends?

Yes. SumUp processes settlement seven days a week at 7am. Friday takings arrive at 7am Saturday; Saturday takings at 7am Sunday. Whether the deposit appears in your account depends on when your bank processes incoming Faster Payments.

What happens if my phone dies while using SumUp Air?

The Air stops accepting card payments. The reader connects via Bluetooth and uses your phone’s internet connection. No phone means no network connection, so card payments cannot process. SumUp Solo (£79 +VAT) has a built-in SIM and works without a paired phone.

Is Payments Plus worth it?

Only above approximately £3,800/month in card turnover. Below that threshold, the £19/month subscription costs more in absolute terms than the saving from the lower 0.99% rate. At £3,800+/month, Payments Plus also includes 24/7 customer support, which is not available on the PAYG plan.

Does SumUp accept American Express?

Yes. SumUp Air accepts American Express at the same 1.69% flat rate. No premium-card surcharge on Amex. That applies on the PAYG plan and on Payments Plus (0.99% on PP).

Can I use SumUp without a monthly fee?

Yes. The PAYG plan has no monthly fee. You pay 1.69% per in-person transaction and nothing else. There’s no contract and no minimum monthly spend. Payments Plus at £19/month is optional and only saves money above £3,800/month in turnover.
