Best Card Machines for Small Business UK 2026
What Are the Best Card Machines for Small Business?
Quick Answer: The best card machines for small business depend on your specific needs. Countertop terminals work best for fixed locations like shops and restaurants. Portable Wi-Fi terminals suit businesses moving between areas (salons, hotels). Mobile GPRS terminals are ideal for tradespeople and mobile businesses.

How to Choose the Best Card Machine for Your Small Business
Decision Framework
Ask yourself these questions:
- Where do you take payment? Fixed location = countertop. Within premises = portable. Customer locations = mobile.
- How many transactions daily? High volume = countertop for better rates. Lower volume = portable/mobile acceptable.
- What’s your monthly card turnover? Affects which providers offer best rates for your terminal type.
- Do you need receipts? All terminals offer receipts, but mobile terminals have built-in printers.
- What’s your Wi-Fi reliability? Poor Wi-Fi = avoid portable terminals, use countertop or mobile instead.
Essential Features to Look For
Regardless of terminal type, the best card machines for small business should include:
Payment Method Support
- Contactless payments: Essential for modern business – contactless limit now £100 in UK

Card Machine Costs for Small Business
Understanding the costs helps you budget and compare providers effectively. Card machine pricing typically includes:
Transaction Fees
What it is: A percentage of each transaction plus a fixed fee per transaction.
Varies by: Your business type, monthly volume, terminal type, and provider.
Important: Higher monthly volumes typically secure better percentage rates.
Monthly Fees
What it is: Fixed monthly charge for terminal rental and service.
Range: Some providers charge no monthly fee, others charge monthly rental.
Consider: Balance monthly fees against transaction rates – low monthly fees may mean higher transaction costs.
Setup Costs
What it is: One-time charge for account setup and terminal delivery.
We Tranxact advantage: Many of our provider partners waive setup fees entirely.
Terminal Purchase vs Rental
- Rental: Lower upfront cost, but ongoing monthly payments. Good for testing or short-term needs.
- Purchase: Higher upfront cost, but no monthly rental fees. Better long-term value for established businesses.

Common Mistakes When Choosing Card Machines
1. Choosing Based on Terminal Cost Alone
A cheap or free terminal often comes with high transaction fees that cost you more long-term. Calculate total cost based on your monthly transaction volume, not just the terminal price.
2. Not Considering Your Actual Business Model
Don’t choose a countertop terminal just because it’s cheapest if you actually need mobility. The wrong terminal type will frustrate you and your customers daily.
3. Ignoring Transaction Fees
Transaction fees compound over time. Even a 0.5% difference in rates costs a business processing £50,000 monthly an extra £250/month (£3,000/year).
4. Signing Long Contracts Without Comparison
Many providers lock you into 2-3 year contracts. Compare multiple providers before committing. We Tranxact helps you compare options without obligation.
5. Not Checking Wi-Fi Coverage
Portable terminals need reliable Wi-Fi throughout your premises. Test coverage before choosing portable over countertop or mobile options.
6. Overlooking Integration Needs
If you use EPOS, booking systems, or accounting software, ensure your card machine integrates properly. Incompatibility causes admin headaches and double-entry.

Best Card Machines for Small Business – Frequently Asked Questions
What is the best card machine for a small business UK?
The best card machine depends on your specific business needs. Countertop terminals suit fixed-location businesses like shops. Portable Wi-Fi terminals work best for restaurants and salons. Mobile GPRS terminals are ideal for tradespeople and mobile businesses. We help you assess your needs and choose the right type.
How much does a card machine cost for a small business?
Card machine costs vary significantly by provider, terminal type, and your monthly processing volume. Costs include transaction fees (percentage-based), potential monthly fees, and setup costs. We obtain custom quotes from multiple providers so you can compare actual costs for your specific business.
Can I get a card machine with no monthly fee?
Yes, several UK providers offer card machines with no monthly fees, though transaction percentages may be slightly higher. Whether this is better value depends on your monthly transaction volume. We help you calculate which pricing structure saves you money.
Do I need a business bank account to get a card machine?
Yes, you need a UK business bank account to receive card payment settlements. Personal accounts are not acceptable for merchant services. The account must be in your business name (sole trader or company name).
How long does it take to get a card machine?
Most UK businesses receive card machines within 3-5 working days after approval. Approval for standard businesses typically takes 24-48 hours. Once approved, terminals are delivered by courier and can be activated immediately upon receipt.
Can I accept contactless payments with any card machine?
Yes, all modern UK card machines accept contactless payments up to £100 (increased from £45 in 2021). All terminals also accept chip and PIN, magstripe, and digital wallets like Apple Pay and Google Pay.
What happens if my card machine breaks?
Most providers offer next-day replacement for faulty terminals under warranty or rental agreements. If you own your terminal, replacement policies vary by provider. We ensure you understand support terms before choosing a provider.
Can I use the same card machine at multiple locations?
Mobile GPRS terminals can be used anywhere. Countertop and portable terminals are typically registered to one business address. If you have multiple locations, you’ll need a terminal for each location or a multi-site merchant account setup.
Do card machines work with my existing till or EPOS system?
Many card machines integrate with popular EPOS systems, but compatibility varies by provider and EPOS brand. We help identify providers offering terminals compatible with your existing systems to avoid integration issues.
How do I know which card machine provider is best?
The best provider depends on your business type, transaction volumes, and specific needs. Rather than choosing blindly, we recommend comparing quotes from multiple providers. We facilitate this comparison process and help you evaluate options objectively.
