16 Best Credit Card Machines & Readers

Updated August 2021

When you need a mobile card payment machine (aka a card reader), you have two choices:

  1. Buy a mobile card reader from a payment facilitator (PayFac) such as Square or SumUp and pay a fixed transaction fee, with no contracts.
  2. Sign a contract with a merchant services provider and pay a monthly fee for each card reader machine or buy one outright. The card transaction fees are variable depending on your business and the terms of your specific contract.

The best choice is normally determined by your:

  • Business type
  • Average card turnover
  • Typical transaction size

As a rough guide, mobile card readers from PayFacs only make commercial sense for SMEs with a relatively low card turnover and/or a low average transaction value. 

TypeRenting (excl VAT)Buying (excl VAT)
Mobile card reader£16 – £149
Countertop PDQ£15 – £50/month£250 – £450
Portable PDQ£15 –  £80/month£250 – £450
Mobile PDQ£50 – £125/month£200 – £255

Before we get into which option may be right for your business, let’s cut to the chase and list the best card readers in the “relatively high transaction fees in exchange for no monthly contracts” category. Their main qualities are quick approvals and ease of use.

Read our comprehensive Square Card Reader review here.

Verdict: Square provides one of the most feature-rich mobile card readers and payment systems available without having to pay a monthly fee. It also integrates seamlessly with the Square ecosystem of ePOS software and hardware.

Zettle Reader 2

The Zettle 2 is the Square Reader’s biggest competitor with with each reacting to each other’s price reductions and tech improvements. Since Paypal bought out iZettle in 2018 (breaking competition rules as a result) they have retired their Paypal Here card reader and focused on the recently rebranded Zettle range of card readers (previously iZettle).

Zettle’s mobile card reader supports contactless and Chip & PIN payments at same fixed rate of 1.75% even for foreign and premium cards.  Visa, V Pay, Mastercard, Maestro, American Express, JCB, Diners Club, UnionPay, Discover, Apple Pay, Google Pay and Samsung Pay are all accepted.

A key selling point with Zettle’s reader is speed. It quickly boots up within 2 seconds, processes payments in as little as 5 seconds and you get roughly 8 hours of active use from a single charge. This makes Zettle 25% faster than most mobile card readers currently on the market when it comes to accepting payments and your money will be deposited in your bank within 1-2 business days – also faster than most of the competition.

Read our comprehensive Zettle review here.

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.

SumUp Air

sumup air

SumUp have responded to the price drop of their main competitors and currently matching their device cost. Their transaction fees are also slightly less than charged by Square & Zettle.  

This tiny card reader needs to connect to the Sumup App on a smartphone or tablet via bluetooth to work and supports payments by contactless (NFC) and Chip & PIN, as well as Apple Pay and Android Pay. All major credit cards are accepted and payouts to your bank account should be completed within 2-3 days.

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.

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. 

Barclaycard Anywhere

barclaycard anywhere card machine

The most affordable entry on this list is most suitable for small and seasonal merchants. This card reader accepts Visa, MasterCard, JCB, Apple Pay and Google Pay payments.

With Barclaycard Anywhere, merchants can send digital receipts to their customer’s email addresses. It has a card slot and a swipe slot for different methods of taking card payments. The card reader accepts chip and PIN, contactless and magnetic stripe transactions.

Very lightweight and compact, Barclaycard Anywhere comes with its own app that works with Android and iOS systems and connects with the card reader via Bluetooth.

The merchants that use Barclaycard Anywhere have access to a dedicated online portal where they can view and export their transactions, add or delete employees.

Verdict: Cheap, no-frills, pocket-sized card reader with transaction fees undercutting its rivals.


16 Best Credit Card Machines & Readers (Updated Aug '21) slider go

MyPOS Go is another no contract card reader that is targeted at those who don’t need all the bells and whistles of some payment solutions and are looking for simplicity at a low price.

The card reader is not going to win any design awards but it’s sturdy and those considering buying it are likely to do so because of its competitive transaction fees. 

It includes an unlimited data plan, valid across Europe and charges a commission of about 1.75% 0.99% on Mastercard and Visa transactions. It offers a free e-money merchant account with dedicated IBANs in 14 currencies, instant access to accepted funds and free access to the iOS and Android myPOS mobile app.

In terms of functionality, it can accept contactless payments via most debit / credit cards or mobile wallets but this Go version can not print receipts and does not have a touchscreen. Therefore a customer’s email address or mobile number will need to be typed in on the key pad if they want it sent by text or email.

If you are looking for more advanced functionality they also have myPOS Mini (£119+VAT) and the myPOS Smart N5 (£299+VAT).

Verdict: Overall, this would suit a small business or sole trader who is looking for a cheap no contact card reader that has lower than average transaction fees. However, the £3 per transfer to UK bank accounts may put off some.

No Contract Card Readers With Printers

For those businesses looking to offer their customers receipts, Square and Sumup also offer mobile card readers with built in printers whilst Zettle bundles in a bluetooth battery operated printer. As you can see below, this significantly increases the price of the hardware.

Credit Card Machines With Low Transaction Fees & Monthly Contracts

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.

If you are processing above this £2K per month level, or expect to, then we can help find you the best payment processor for your specific business. 

Fill in our short form below and we’ll recommend who we think would be best for your business and get better rates than you’d get if you went direct.

When you sign up with an merchant acquirer or ISO and want to take face to face payments you’ll need to select a PDQ (process data quickly) machine that are typically made by Verifone, Ingenico, Pax Technology, Clover, Spire Payments, Datecs or Miura Systems. They will fall into one of the following categories (we are discounting POS systems as they fall into a different subset):

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.

 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.

They’re also hooked up to your main power supply, which means countertop card machines are always on when you need them, without having to worry about charging your devices.

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.

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.

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.

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.

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.

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 get take payments on the go such as plumbers, taxi drivers and builders.

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

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.

Flexibility is the obvious benefit but you’ll have to pay significantly more to buy or rent fully mobile PDQs 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.
