In the UK, small companies must accept credit and debit cards. Whether you run a market stall, a café, or an online shop with a physical presence, having a reliable card reader ensures smooth transactions and better customer satisfaction. In 2025, the UK card payment landscape is dominated by versatile machines that cater to various business models.
This guide compares the top 10 card payment machines ideal for small business in the UK based on cost, connectivity, features, and support. From mobile card readers like SumUp and Square to countertop terminals like Tyl and Worldpay, we’ve covered options that suit every scale and type of business.
What are the best card payment machines for small business in 2025?
To select the best card payment machines for your small business in the UK, consider your transaction volume, business location, device portability, and your preference for pay-as-you-go or contract models.
Top criteria to consider:
- Hardware cost: One-off purchase vs monthly rental
- Transaction fees: Flat percentage or tiered by volume
- Connectivity: Wi-Fi, Bluetooth, 3G/4G, or Ethernet
- POS integration: Does it support inventory, reports, staff access?
- UK support: Availability of helpdesk, bank integration, or PCI compliance
Key selection factors:
- Low transaction fees for small margins
- Minimal or no upfront cost for new startups
- Wi-Fi or 4G support for remote selling
- Integration with mobile apps and accounting software
- Next-day fund settlement
- Security compliance: PCI-DSS & end-to-end encryption
Why should UK small businesses invest in card payment machines?
How do modern card terminals improve checkout speed and customer experience?
These days, contactless, chip and PIN, and mobile payments like Apple Pay and Google Pay are all supported by card readers. They reduce queue times, enhance customer satisfaction, and enable smooth digital receipts via email or SMS.
Most devices connect wirelessly, meaning less hardware and faster setup times. Tablets or smartphones can become full-featured POS systems when paired with these readers.
What are the cost-saving benefits over traditional PDQ machines?
Old-school PDQ terminals often come with long contracts, expensive maintenance fees, and limited compatibility.
Modern readers offer:
- No monthly contracts (e.g. Square Reader, SumUp Air)
- Simple flat-rate pricing
- Better connectivity options
- Easy mobile setup
Examples:
- SumUp: Pay-as-you-go, 1.69% fee, no rental costs
- Zettle: 1.75% fee, instant PayPal settlement
For small firms, these options provide greater flexibility and reduced operational expenses.
How much do card machines cost to run?
Hardware, transaction fees, and maintenance or service fees are all included in the cost of a card machine:
- Device cost: Mobile readers range from £19 to £89; countertop terminals can cost £199 or more, or be rented from £10/month.
- Transaction fees: Typically 1.5%–1.75%, depending on provider and volume.
- Compliance and extras: PCI-DSS fees (~£2–£5/month), setup or exit fees, and monthly service charges if on contract.
A pay-as-you-go model (like Square or Zettle) typically incurs no ongoing monthly fees, making it cheaper for low-volume traders.
Countertop Vs Portable Vs Mobile Card Readers
- The purpose of countertop card machines is to be utilised at specific checkout counters within your establishment. They don’t have any portability, but their connectivity is typically very dependable. They work well for companies like grocery stores and small retailers that have a set point of payment.
- Anywhere on your website, you may accept card payments using portable credit card machines, which are battery-operated gadgets that connect to Wi-Fi. They’re best for cafes and restaurants.
- Even more portable, mobile card readers run on batteries and accept card payments anywhere you are via a GPRS (3G or 4G) signal. Additionally, they typically have Wi-Fi capabilities. They work well for street food trucks, pop-up stores, marketplaces, festivals, and pretty much anywhere else.
