What is the best card reader?

On balance, we believe the best overall pay as you go (i.e. no monthly contract) mobile card reader for small businesses is Square.

The table below lists it competition. You can see the cost of the devices are low and quite similar thanks to perpetual special offers and competitor price matching.

It’s best to pay little attention to the cost of the device and focus on their transaction fees, functionality, speed and customer support when comparing them.

What is the cheapest way to take card machine payments?

The cheapest way for small businesses in the UK to take card payments will depend on the business type, the average card turnover and typical transaction size.

Small businesses in the UK with a relatively low card turnover and/or a low average transaction value will likely be better off with a ‘pay as you go’ no contract mobile card readers like those offered by Square, Zettle or SumUp.

They do have relatively high transaction fees of 1.69% – £1.75% but savings can be made on other fees.

The five companies below mobile pay as you go card machines that don’t require you to sign up to a monthly contract. Once you buy the card reader you will be charged a percentage of the transactions you process.

Now you’ve seen a summary of the best card readers, let’s look at them in a bit more detail.

I want to reduce my card processing fees – what are my best options?

The card processing fees for the card readers listed in the table above relatively high. 

If your businesses takes over £2,000 per month in card transactions per month (or expects to) it normally makes commercial sense to sign up with with a merchant services provider (i.e. Worldpay, Barclaycard etc) that can offer significantly lower transaction fees.  

Fill in the form here and will find you the best one for your business. 

A contract will need to be signed (typically with minimum term of 12 months) but on balance the benefits will make this this the best option when you process more than £25K per year.

If you believe the ‘pay as you go’ mobile card readers are the way to go there are only a handful to consider.

Verdict: Zettle’s card reader offers some of the fastest payment processing in the industry right now, along with extensive support for credit cards and mobile payment platforms. The company also offers a wider range of online payment solutions, making Zettle a good option for SMEs that sell to customers face-to-face and over the internet.

What other card readers do SumUp offer?

They also offer the SumUp 3G for £89+VAT or £119+VAT if bundled with the printer which can work where there is a WiFi, 3G or GPRS connection, since it has a built-in SIM. This is a fully standalone reader and does not need to be paired with a smartphone or tablet.

Does SumUp offer payment links?

They also offer payment links that can be emailed or included within their invoice template but payments via this method have an increased transaction fee of 2.5% (they are higher risk as the card holder is not present).

Read our comprehensive Sumup review here.

Verdict: A solid choice but the Sum Air and associated app is not quite at the level with the 2 card readers above.

What are the benefits of the MyPOS Go?

Why sign up to a card machine provider that has a minimum monthly contract?

If you are transacting more than about £2,000 per month on card, it is often cheaper to sign up to a merchant acquirer or Independent Sales Organisation (ISO) and then select the card machines they have available. 

When your card turnover exceeds a certain level the payment processor you work with will make far more of a difference to your bottom line and stress levels than the card machine you use.

Portable PDQ£15 –  £80/month£250 – £450
Mobile PDQ£50 – £125/month£200 – £255

Which card machine providers are best?

If you sign up with a payment processor that provides card machines the models available will typically be made by Verifone, Ingenico, Pax Technology, Clover, Spire Payments, Datecs or Miura Systems.

They will either be classed a countertop, portable or mobile card machines (we are discounting POS systems as they fall into a different subset).

What are countertop card machines?

Countertop card machines are usually a part of the tills’ point of sale (POS) system. They work by connecting to the internet or a phone line. Countertop credit card machines are suitable for shops that take payments at the checkout or till.

What are the benefits of countertop card machines?

They’re generally the cheapest range of card machines on the market and they’re also the fastest, thanks to connecting directly to your phone or broadband line – so payments are processed in seconds.

What are the cons of countertop card machines?

The only real downside to countertop card machines is they’re not very portable due to their wired connections. Whether this is a problem for you or not depends on how your business operates.

What are portable card machines?

Portable card machines are best suited for hospitality businesses, like cafes, bars and restaurants, as they can process payments at the customer’s table. Portable credit card readers work via a Bluetooth or WIFI connection.

Are portable machines the best for table service?

As the same suggests, portable card machines give you a little more room to work with when it comes to accepting payments. These are your best option if you want to accept payments from customers at their table so they can continue enjoying the end of their evening with minimal interruption.

Are portable PDQ machines affordable?

Portable PDQ machines aren’t all that more expensive than countertops either, which means they’re still an affordable option for relatively small and midsize establishments.

What are the cons of portable PDQ machines?

However, there’s a limit to how much portability you get from their Bluetooth connections and you need to stay within range to accept payments. You also need to keep an eye on batteries to make sure you don’t fall short of power at the crucial moment.

What are fully mobile card machines?

Mobile card machines work via a SIM card (GPRS/GSM). As they don’t need a WIFI or Ethernet connection they’re ideal for businesses that need to take payments on the go such as plumbers, taxi drivers and builders.

What are the benefits of fully mobile  machines? 

Fully mobile PDQs give you the freedom to accept payments anywhere without worrying about cables or connections getting in your way.

What businesses are mobile machines best suited to?

For sales reps travelling the country, delivery services or sole traders  who need to visit customers in their homes, these are the machines you want. As long as there’s a 3G mobile signal, you can collect payment from customers in any location and these are widely used at events where traditional connection methods can be a little tricky.

What are the cons of fully mobile machines?

Flexibility is the obvious benefit but you’ll have to pay significantly more to buy or rent fully mobile card payment machines compared to countertops and portable machines. You also have to accept a slight drop in performance, too, as accepting payments over a mobile connection will obviosuly take a little longer than those using cables or wireless broadband.
