Card now beats cash at the UK till, so taking it isn’t optional any more. The good news: you can be live in a day, and the cheapest start costs almost nothing. This guide matches how you sell to the right method, the real fees, and the rules.
Taking Card Payments at a Glance
Find your situation in the table, then jump to the section that fits. We built it so you can self-identify in one scan, whether you sell across a counter, online, over the phone, or on the move.
| Where you sell | Best method | Typical 2026 cost | What you need |
|---|---|---|---|
| Fixed shop counter | Countertop or smart terminal | ~1.5% to 1.75% per tap; terminal £149 or £15 to £30/mo | Terminal, business account |
| Market stall, mobile, pop-up | Mobile reader or Tap to Pay | ~1.69% to 1.75% per tap; reader from £19 | Smartphone (reader optional) |
| Online store | Payment gateway or plugin | ~1.4% to 1.5% + 20p per sale | Website, gateway account |
| Over the phone | Virtual terminal (MOTO) | ~2.5% per transaction | Browser, MOTO-enabled account |
| Subscriptions, recurring | Recurring card or Direct Debit | Card ~1.5%; Direct Debit ~1% + 20p | Billing platform |
| In person and online | One provider across channels | Blended ~1.5% to 1.75% | Account covering both |
No single provider wins every row. We rate Square the easiest all-rounder to start with, but we wouldn’t put a busy shop on flat-rate forever. Our payment processing hub compares the shortlist once you know your method.
The Main Ways to Take Card Payments
There are four ways to accept a card in 2026, and we see most businesses use one or two. Pick by where the customer is standing when they pay, not by which advert you saw first.
In-Person Card Payments
Selling face to face gives you three hardware routes. The simplest is a mobile reader like the Square Reader, SumUp Air, or the Zettle Reader.
A reader pairs with your phone over Bluetooth and starts from £19. A Leeds market trader can be taking taps the same afternoon. That’s the lowest-friction way in for any sole trader, and the one we’d try first.
A countertop or smart terminal suits a fixed till. It runs its own screen and connects over Wi-Fi or a SIM, and it links to your EPOS so the day reconciles itself instead of by hand.
Tap to Pay needs no hardware at all. Your NFC phone becomes the reader, so a sole trader can accept contactless for £0 in kit. That’s the cheapest possible start, full stop.
Online Card Payments
Selling online means a payment gateway: the checkout that captures and encrypts the card. Stripe and PayPal are the common picks, and both settle the money too.
A hosted checkout sends the customer to the provider’s secure page, which keeps card data off your servers and shrinks your compliance to the simplest level. For most small shops, that’s the trade-off we’d pick.
If you run Shopify, WooCommerce, or Wix, a plugin wires it up in minutes. Payment links are the lightweight option: you generate a link and send it by email, SMS, or WhatsApp, no website required.
Phone Card Payments (MOTO)
Mail Order and Telephone Order (MOTO) lets you key a card in yourself while the customer reads it out. You do it through a virtual terminal, a secure web page from your provider.
It suits a Brighton physio taking deposits by phone, or a B2B wholesaler invoicing trade accounts. The catch is the rate: with no card present, fraud risk is higher, so MOTO runs near 2.5%.
Recurring Card Payments
If you bill the same customer on a schedule, automate it. Recurring card billing stores the card and charges it each cycle, which suits memberships, subscription boxes, and SaaS.
Direct Debit is the cheaper cousin. It pulls from the bank, not the card, so a Glasgow gym billing members monthly pays around 1% + 20p and loses fewer payments to expired cards. That gap matters at scale.
How Much It Costs to Take Card Payments
Three costs make up the bill: the per-transaction fee, the hardware, and any monthly charge. The fee model drives the total, so understand it before you sign anything.
| Provider | In-person | Online | Hardware | Monthly |
|---|---|---|---|---|
| Square | 1.75% | 1.4% + 25p | Reader £19, Terminal £149 | £0 |
| SumUp | 1.69% | 2.5% | Air £34, Solo £79 | £0 (or £19 plan) |
| Zettle | 1.75% | 2.5% | Reader £29, Terminal £149 | £0 |
| Stripe | n/a | 1.5% + 20p | None | £0 |
| Worldpay / Barclaycard | ~1.5% to 1.6% | 1.3% + 20p | Rented £15 to £30/mo | + PCI ~£5 |
Flat-rate pricing charges one percentage on every sale. It’s simple and predictable, which is exactly why it suits low and mid volumes. You always know what a sale costs you.
Interchange-plus splits the fee into the bank’s cut, the scheme’s cut, and the processor’s markup. When a customer pays on a cheap debit card, that saving reaches you instead of vanishing into a blended rate.
Here is the threshold we keep coming back to. Below roughly £30,000 to £50,000 a month, flat-rate aggregators win on price and simplicity. Above it, interchange-plus usually beats them even after terminal rental.
A Norwich cafe at 1.75% on £40,000 a month pays £700. A negotiated 0.8% plus £30 rental would cost £350. We’ve seen plenty of growing shops leave that gap on the table for a year.
What You Need to Get Started
The starting kit is short. For in-person, you need a smartphone and a reader, or just an NFC phone for Tap to Pay. For online, you need a website or a payment-link account. Hardware is optional more often than people assume.
You need a business bank account to receive payouts. This is the trap that stings new owners: if you trade under a registered name, aggregators and acquirers won’t settle into a personal account. Sort the account first.
You will pass a quick identity and business check (KYC). When you apply, have your photo ID, business bank details, and Companies House number ready. A sole trader needs less, but still needs a genuine business account to get paid.
One eligibility point to check early: not every provider accepts sole traders or certain trades. If you’re in a flagged sector, confirm acceptance before you build a checkout around them.
How to Set Up Card Payments Step by Step
Six steps, in order. Most people clear the lot inside a week, and aggregators can have you live the same day.
1. Pick your method. Map it to where you sell: counter, online, phone, or a mix. Get this right and every later choice narrows itself. Get it wrong and you pay for kit you never use.
2. Choose a provider. Match your monthly volume to the fee model. Under £30,000 a month, start with a flat-rate aggregator. Above it, get interchange-plus quotes from an acquirer.
3. Apply and pass KYC. Upload ID, business bank details, and your company number. Aggregators approve in minutes; a traditional acquirer underwrites over one to two weeks.
4. Set up the kit or the checkout. Hardware ships in one to three days. Online, you drop in a plugin or paste your API keys, then connect your accounting feed so reconciliation isn’t manual.
5. Test before you go live. Push a real £1 sale through every channel you will use. Confirm it appears and settles. Don’t take it on trust; test it.
6. Watch the first payout. Square settles next working day; Stripe usually takes about three. Some providers hold your first payout a few days while they verify you. Plan that short gap into your cash flow.
Card Payment Rules and Compliance
Compliance sounds heavier than it is for a small merchant. Pick a mainstream provider and it carries most of the load. You don’t need to become a security expert to take a card.
PCI DSS is the card-data security standard. Almost every UK small business sits at the lowest tier and proves it with a short annual questionnaire (an SAQ). A hosted checkout or a standalone terminal keeps that questionnaire short.
Then there is SCA, the rule behind those approve-in-your-app prompts. When a customer pays online, your gateway runs Strong Customer Authentication through 3D Secure 2 for you. You don’t build it; the provider enforces it.
UK GDPR covers the data itself. The rule is simple: never store a card number in plain text, on paper, or in a spreadsheet. Let the processor tokenise it. We’d still confirm any provider is FCA-authorised before signing.
The compliance reality for small merchants
If you use a hosted checkout, a standalone terminal, or Tap to Pay, your provider absorbs the heavy lifting on PCI and SCA. Your job is to fill in the annual questionnaire honestly and never store raw card details yourself. That’s genuinely most of it.
How to Choose a Card Payment Provider
We rank the factors by what actually moves your bill. Monthly volume comes first, because it decides whether flat-rate or interchange-plus is cheaper for you. Everything else is secondary to that one number.
Settlement speed comes next. Next-day money beats a three-day hold when you are restocking on tight cash flow. Then contract length: aggregators are rolling or contract-free, while acquirers often want twelve to eighteen months.
After that, weigh the fit. An in-person business needs solid hardware and EPOS links; an online one needs a clean gateway and plugins. Check the accounting integration too, or you’re back to manual reconciliation every month-end.
Provider choice is where our reviews earn their keep. Once you’ve settled on a method, compare the shortlist on the payment processing hub rather than trusting any single sales pitch.
Common Mistakes to Avoid
Most card-payment regret traces back to a handful of avoidable errors, and none of them are technical. These are the five we see again and again when people are busy running the shop.
Five traps that cost UK merchants money
The list below is the short version. Each one is avoidable, and each one shows up in real complaints about UK card processing.
- Skipping the auto-renewal clause. Sign an acquirer contract, miss the 30-day notice window, and you’re locked in for another full term.
- Staying flat-rate as you scale. Past roughly £50,000 a month, interchange-plus is usually cheaper even with terminal rental.
- Ignoring settlement times. A three-day hold can throttle your cash flow if you restock fast.
- Paying for features you never use. EPOS bundles and premium plans bought for a single report add up.
- Using a personal account. If you trade under a registered name, providers won’t pay out to it.
Frequently Asked Questions
Can I take card payments without a card machine?
Yes. Tap to Pay turns an NFC smartphone into a contactless reader with no hardware at all. Online, payment links and hosted checkouts take cards without a machine. Over the phone, a virtual terminal does the same from your browser.
How quickly do I get paid?
It depends on the provider. Square settles next working day as standard. Stripe is typically about three business days for UK accounts. Some hold your first payout a few extra days while they verify you, so plan that gap into your cash flow.
Do I need a business bank account to take card payments?
In practice, yes. If you trade under a registered business name, providers won’t settle payouts into a personal account. Sole traders have a little more leeway, but a dedicated business account keeps payouts and bookkeeping clean.
What is the cheapest way for a small business to take cards?
For low volume, a flat-rate aggregator wins: no monthly fee, a reader from £19, or £0 with Tap to Pay. Once you pass roughly £30,000 to £50,000 a month, an interchange-plus contract usually works out cheaper.
Do I have to handle PCI compliance myself?
Mostly no. With a hosted checkout, a standalone terminal, or Tap to Pay, your provider carries the bulk of PCI DSS. You complete a short annual questionnaire and never store raw card numbers yourself. That is the whole obligation for most merchants.
Are online card fees higher than in-person fees?
Usually, slightly. In-person taps run around 1.69% to 1.75% flat. Online sales tend to add a fixed pence charge per transaction, near 1.4% to 1.5% + 20p. Phone (MOTO) payments are the priciest, around 2.5%, because fraud risk is higher.
How We Created This Guide
How we created this guide
Sources. We reviewed published 2026 pricing from Square, SumUp, Zettle, Stripe, Worldpay, and Barclaycard, alongside the FCA on Strong Customer Authentication, UK Finance, and the PCI Security Standards Council.
We didn’t rely on provider marketing for factual claims. Fee figures are typical 2026 UK ranges for small businesses and move with your card mix and volume, so confirm current rates with any provider before you sign.
Verification date. Pricing and rules were checked in June 2026. Contactless limits, SCA exemptions, and fee structures change, so treat the figures as a starting point, not a quote.
