How to Choose the Best Card Machine for Your Business
1. Calculate Your Monthly Card Sales
The #1 factor determining the best provider. Under £5k/month? Square/SumUp. Over £10k/month? Dojo. Over £50k/month? Negotiate custom rates.
2. Consider Your Business Type
Restaurants: Need wireless, table-service features. Retail: Need EPOS integration. Mobile: Need 4G built-in, long battery.
3. Check Contract Terms
No contract (Square, SumUp, Zettle) = flexibility. Contract (Dojo 18m, Worldpay 36m) = potentially lower fees but locked in.
Best Card Machine FAQs
What is the best card machine for small businesses UK?▼
For small businesses, Square Reader (£19) or SumUp (£29) are best - low upfront cost, no monthly fees, simple to use. For growing businesses processing £10k+/month, Dojo offers better value with lower transaction fees despite the monthly subscription.
Which card machine has the lowest fees?▼
Dojo has the lowest transaction fees from 0.79% + 3p for debit cards. However, there's a £9.95-£19.95 monthly fee. For lowest ALL-IN cost, it depends on your monthly sales volume - we can calculate this for you.
What is the most reliable card machine?▼
Worldpay and Barclaycard have the most established infrastructure with 99.9% uptime. They're more expensive but offer dedicated account managers and priority support. Good for businesses where payment downtime means lost revenue.
Which card machine is easiest to use?▼
Square is consistently rated easiest - intuitive app, clear receipts, simple setup. SumUp and Zettle also score highly for user-friendliness. Traditional providers (Worldpay, Elavon) have steeper learning curves.
What is best for high-volume businesses?▼
For £50k+/month in card sales, negotiate custom rates with Worldpay, Barclaycard, or Dojo. High volume gives you leverage to get transaction fees under 1%. Monthly costs become irrelevant at this scale.
Which providers offer next-day funding?▼
Dojo, Square, and SumUp offer next working day settlement as standard. Traditional providers (Worldpay, Barclaycard) typically pay every 3-5 days unless you negotiate next-day terms.
What about integrated EPOS systems?▼
For restaurants/retail needing full EPOS: Dojo, Square, and Zettle integrate with major EPOS providers. Worldpay offers enterprise EPOS solutions. Basic card-only terminals don't integrate.
Which is best for restaurants?▼
Dojo Go is popular with restaurants - wireless, integrated EPOS options, table service features, kitchen printing. Square also works well for casual dining. High-end restaurants often choose Worldpay for reliability.
Do the best card machines require contracts?▼
Square, SumUp, Zettle: No contracts (pay-as-you-go). Dojo: 18-month contract. Worldpay/Barclaycard: Typically 24-36 month contracts. No contracts = flexibility. Contracts = potentially better rates.
Can I trust online reviews of card machines?▼
Take reviews with caution - many are paid affiliates or fake. Trustpilot reviews are more reliable. Best approach: Try a provider for 1-2 months (no contract options) and see how it works for YOUR business.
