If you want to succeed in this increasingly cashless society, you need a small business card machine that will take the hassle out of payment processing and help to drive sales.

And in the time of Covid-19, a card machine is the best way to keep you and your customers safe while taking payments.

But with so many different card machines on the market, all promising the world, how do you choose the one that’s going to help your business succeed?

That’s where we can help. We’ve been advising startups and small businesses for more than 20 years, helping them to find the products and services that suit their needs. Our quick and free card reader comparison tool can do just that for you. Just answer a few simple questions, and our expert team can do the comparison legwork to match you with the best card reader for your business.

Or, check out our in-depth reviews of the 6 best card machines currently available to small businesses to help you make your decision. Below, we break down the costs, features, and pros and cons of each, and answer some of your most frequently asked questions about choosing a card reader.

Traditional card machines, mobile card readers, chip-and-pin machines: What's the difference?

While traditional card machines are associated with banks and merchant account providers, mobile card machines are supplied by independent businesses that tend to provide all-in-one payment taking solutions that include:

  • A merchant account
  • A payment gateway
  • Point of sale equipment 

So which is the best option for small businesses?

A mobile card reader is a small but mighty piece of hardware. It connects to a tablet or smartphone, and accepts payments from debit and credit cards, and mobile payment apps including Google Pay and Apple Pay. 

Great for businesses like coffee shops, beauty salons, bars, restaurants and any form of retail, a mobile card reader will quite literally mobilise the way your business takes payments, boosting sales and increasing your capacity for great customer service.

A traditional card machine is the type of card reader that customers are probably most used to seeing, as all big stores and supermarkets use them. These card readers are often rented from suppliers, and can either be wired or wireless. 

While mobile card reader suppliers often charge businesses a set transaction fee, banks that supply traditional card readers will charge a transaction fee that’s dependent on your total volume and value of sales.

…And what about chip-and-pin machines? Both of the above will offer the option to use chip-and-pin technology to take card payments. Technically, a chip-and-pin machine is any device in which a card can be inserted or swiped and a PIN code entered for a transaction to be made.

However, with contactless payments having become a much more popular payment method over the last few years, people often associate the term ‘chip-and-pin' with the older-looking, larger card machines than the smaller, more recently designed card readers.

Whether you’re looking for a card machine with the lowest transaction fees, or one that you can set up with your smartphone, below we review the UK’s leading options; from the cheapest card payment machine to the best mobile card reader for small businesses.

Read on for a full-fat breakdown of the six best card machines for small businesses.


But before we start, here are our three top pointers for finding the best machine:

Credit card1. As we’ve said above, your business's specific requirements will determine which card machine is best for you, which means finding one that's appropriate for your business size, the number of monthly transactions you expect to process, and the industry you're in. Don’t worry, we can do all that hard work for you. Just tell us about your needs, and we’ll match you to a range of top UK providers.
Credit card 2. Card machine providers charge a range of initial costs and recurring fees. Make sure all pricing information is clear before you commit.
Credit card 3. Planning to scale or take on more staff? Make sure you choose a solution that can grow with your business!

How we chose our top card readers

To make our list of the best card machines for small businesses, we pitched the providers against one another and rated them on the following areas:

  • Value for money – how competitive is the device cost, transaction fees and associated monthly costs?
  • Ease of use – is the card reader and its accompanying POS system easy to set up and use?
  • Customer reviews – what do the customers say about the card reader and any associated equipment and software?
  • Features – does it offer all the features small businesses need

Chip and pin machines: Buying vs renting

Whether it makes sense to buy or rent a card machine depends on your appetite for flexibility as well as your individual business set-up.

Buying a card machine

Chip and pin machines don’t have to cost the earth, and getting your own device will often save you in the long term with no monthly commitment or exit charges.

These are the pros and cons of buying a chip and pin machine:


  • No monthly commitment
  • Cheaper in the long-term
  • Pairs with EPOS systems
  • Your device, your rules
  • Competitive advantage


  • Initial costs
  • No replacements
  • Can go out-of-date

Renting a card machine

Long or short term card machine hire is a popular option for small businesses. Perhaps you only work seasonally, or you just like the added maintenance and support that comes with renting equipment.

These are the pros and cons of card machine hire:


  • No purchase costs
  • Maintenance included
  • Ideal for short-term
  • Support team on hand
  • Latest device renewals


  • No ownership
  • Higher costs long-term
  • Contract lock-ins
  • Possible exit fees

Costs can be tricky to compare, right? Just because one card reader device is cheaper initially doesn’t mean the transaction fee structure won’t result in a higher overall monthly cost, and this can vary from business to business.

After 20 years advising small businesses on taking payments, we’ve used our knowledge to build a card reader comparison tool that can help you find the card reader that will offer your business the best value for money. All we need from you is a few key details.

Key questions when choosing a card reader

We've answered some key questions that customers have when choosing the right card reader

Do fees differ between providers? 

Some providers have flat rates whereas others will offer cheaper fees the higher your sales volumes. Check that your sales volume will match the provider’s minimum requirements to make the most of any deals to be had

What is a mobile card reader?

A mobile card reader is a device that you can take to your customers when it's time to take payment. It's especially helpful if you’re in the hospitality industry and it helps with social distancing measures in the current Covid-19 pandemic

How many card readers should I have?

Customers don’t like waiting to pay, and poor service might stop them coming back – make sure you have enough machines to allow maximum payment efficiency

Which types of card do I need to accept?  

Most people understand that small businesses may only be able to accept a limited number of cards, but the more options you give your customers to pay with, the better. Most card readers will accept Visa, MasterCard, Maestro, and American Express

Why should I start accepting contactless payments?

One in three UK card payments are made using a contactless card or e-wallet. Therefore, having a contactless point of sale option is a must, especially if you’re often making sales of £45 or less

What's the best card reader for iPhone? 

All mobile card readers are compatible with the iOS operating system and so are the majority of accompanying apps. However, some accompanying apps, such as iZettle Food and Drink for hospitality businesses, are only compatible with iPads.
