What is a card payment machine?

A card payment machine is a device that allows businesses to accept payments from customers via debit or credit cards. With the decline in cash usage, card payment machines have become essential for businesses of all sizes to provide a seamless payment experience, whether it’s through contactless, chip and PIN, or mobile payment options.

There are several types of card payment machines available, each designed to suit different business needs. Traditional card terminals are often seen in larger retail stores, requiring a physical connection to a phone line or the internet. While they tend to have higher setup and maintenance costs, they are still widely used in fixed locations.

However, for small businesses or mobile businesses, portable card payment machines have become a game changer. These compact, affordable devices connect to your smartphone, making it easier than ever for businesses to accept card payments on the go. Whether you're a mobile hairdresser, a masseur, or running a food truck, portable card readers offer a simple, cost-effective solution that allows you to take payments anywhere.

For businesses with fixed locations or those requiring integration with a cash register, there are card machines specifically designed for permanent setups. Regardless of your business type or location, there’s a card payment machine to suit your needs, enabling quick, secure transactions and ensuring you never miss a payment.

Choosing the best card payment machine for you

The way people pay for goods and services has evolved over the last decade, with card payments now accounting for around 85% of all transactions in the UK. Among these, contactless payments make up over a third of all card transactions, reflecting a growing preference for quick, convenient payment methods. As cash usage continues to decline, having a card payment machine is no longer just an option; it's a necessity for businesses of all sizes.

With so many types of card payment machines available, it's important to choose the right one to suit your business needs. From compact card readers that connect to your smartphone via an app, to fully integrated systems that work with tills, there are solutions for every business type, whether you're a mobile entrepreneur or a retail store owner.

To find the best card payment machine for your business, start by considering the features that are most important to you. Do you need contactless payments? Will you be accepting payments on the go, or do you need a more permanent setup? Once you've determined what your business requires, it's crucial to compare fees and charges between providers to ensure you're getting the best deal without overpaying for unnecessary services.

How to get a card payment machine for your business

Card terminals are linked to a bank account - something that's pretty non-negotiable. This can either be your existing account, or a dedicated merchant account you control and administer.

Some business accounts even come with a free payment terminal included - although this is generally only useful for smaller businesses, as it tends to be the most basic option.

For pay-as-you-go machines, things are pretty simple – send the card machine provider money and a delivery address then wait for it to arrive. You'll probably need to sign up to an app as well.

Contract card payment terminals need a little more.

You need to set up an account to get one - which can mean they need more information up front.

Some typical requirements to sign up for a monthly terminal include:

  • Your business address and VAT number (if applicable).

  • Personal details, such as three years' address history for business partners, shareholders and business owners.

  • Bank sort code, account number and name on account.

Card machine fees explained

Card payment machines charge you in three basic ways - finding the cheapest payment solution for you means you need to balance them.

Card machine cost

This is how much you pay upfront for the machine itself. This can be anywhere from £0 to hundreds of pounds depending on the kit and the ongoing charge.

Transaction charges

This is how much of each sale you give up - expressed as a percentage. So a 1.75% fee means you lose £1.75 for each £100 of sales. Transaction fees can also be dependent on how much money you put through the machine each year.

Monthly fee

As well as transaction fees, you can sign up to a monthly contract. Pay-as-you-go options are available too, but generally come with higher transaction charges.

Which sort of card machine is best for you

Pop ups, stalls and stands

Pop ups, stalls and stands

If you have an occasional pop-up or stall, or only take card payments intermittently, it makes no sense to pay for a monthly contract.

Additionally, you'll want a card payment machine that works over a mobile network - either by connection to your phone or directly.

Regular stalls, stands, pitches and more

If you've got a fixed pitch, plot or more - but lack a dedicated till - extra features can come in handy.

The right card machine can offer a full point-of-sale service you can fit in your hand - including a product library, receipt printing and more.

Fixed shops, bars, cafes and restaurants

If your business operates from a fixed location, having a freestanding card machine at the point of sale - or that you can take to a customer's table - works well.

If your business means travelling to clients – taking payments on the go or similar - you'll want a machine that either connects to your mobile or directly to a network.

How card payment machines work

Customer presents their card

When a customer presents their card, its chip sends the transaction details to your merchant bank account. This sits aside from your business bank account and holds funds while the payment process trundles on.

Payment request is sent

The merchant bank sends the payment request via broadband or a phone line to the customer’s card provider – usually Visa, Mastercard or American Express.

Customer's account is contacted

The card provider transmits a request for payment authorisation to the customer’s bank or credit card provider.

Payment is made, or declined

The transaction goes through if the card details are all correct and if there’s enough money in the account. The payment gets declined if the card details aren’t correct or the customer doesn’t have enough money to cover the transaction.

FAQs

How long will it take for the payment to register in your account?

The time it takes for a payment to appear in your account can vary depending on several factors. Typically, payments may take up to three business days to register, especially if the transaction occurs late in the day, over a weekend, or on a bank holiday. Keep in mind that weekends and holidays may cause delays, as payments are processed during business hours on weekdays.

Do I need a new account?

You don’t always need a new account for card payments, but having one could save you money in the long run. When you accept card payments, the payment service provider — like Mastercard, Visa, or American Express — sends the funds to a merchant account. If you already have your own merchant account, you can use that to receive payments, but setting one up may take longer and incur additional fees.

However, this option can be more affordable if you process many transactions. Alternatively, some card payment providers offer to manage the account for you, allowing you to set up quickly, but they often come with higher transaction fees. So, while a new account is not strictly necessary, it may be a worthwhile consideration depending on your business's sales volume and transaction costs.

What card issuers are covered?

Most card payment machines accept payments from major card issuers like Visa and Mastercard. However, some machines may not support American Express, so it's important to check this before choosing your payment solution. Additionally, mobile payment methods such as Apple Pay and Google Pay are commonly accepted by many modern card machines. To ensure full compatibility, always verify the list of supported card issuers and payment methods for the specific card machine you're considering.

How fast can you get one delivered?

The delivery time for a card payment machine depends on the payment plan you choose. For a pay-as-you-go machine, you can typically apply online and receive it within a few days. In some cases, you may opt for same-day delivery for an additional fee.

Once it arrives, setup is usually quick and easy, taking just a few minutes. On the other hand, if you're signing up for a pay-monthly service, the process may take longer, as the provider needs to conduct account checks and set up your service before dispatching the machine.

Can UK card payment machines accept foreign cards?

Yes, UK card payment machines can accept foreign cards, as long as the payment provider is supported, such as Visa, Mastercard, or American Express. However, it's important to note that processing foreign card transactions may take longer than domestic ones due to additional verification steps or currency conversion. Always check with your payment provider to ensure compatibility with international cards.

Can you have multiple card payment terminals?

Yes, you can have multiple card payment terminals, but it depends on the type of payment machine you choose. For pay monthly card machines, it’s often possible to link multiple devices to the same account, even across different business locations. However, with pay-as-you-go machines, each terminal may require its own independent account setup. Be sure to check with your payment provider for specific details and options based on your business needs.

How secure are card payment machines from fraud?

Card payment machines are designed with strong security features to protect against fraud. When linked to a bank account, the payment process for both debit and credit cards — whether through contactless or chip and PIN — remains highly secure. In fact, if a payment is processed through these methods, the seller typically isn’t liable for fraud, as long as the transaction is approved.

However, there are security risks associated with other payment methods. If you manually key in a card number, use the magnetic stripe, or rely on a signature as confirmation, you could be held liable if the card turns out to be used fraudulently. To minimise fraud risks, it's recommended to use secure payment methods like chip and PIN or contactless wherever possible.
