From market stalls and craft fairs to small shops and service providers, taking payment via your mobile device has never been more accessible to small businesses in the UK.

Mobile card payment devices are simple: they connect to an app on your smartphone or tablet over the internet, and are now one of the easiest and cheapest ways to process card or contactless payments.

Ever since 2012 when Starbucks invested $25m (£16m) in Square, the first mobile card machine founded by Twitter co-creator Jack Dorsey, the market has gone mainstream.

Now, iZettle, SumUp, PayPal and Worldpay have all designed card payment systems for the UK’s small business and start-up scene.

Why take mobile card payments?

Card payments – or cashless transactions – are on the rise in Europe, and have been for some time.

1. Customers want to pay by card

A recent report by the British Retail Consortium (BRC) found that in 2016, for the first time, debit cards had overtaken cash to become the UK’s most popular payment option.

Plus, research from the PPRO Group found that:

  • One in three people never use cash anymore
  • A quarter find having to pay by cash irritating
  • More than a half of retail shops today are paid for by card

2. Mobile card payments have never been cheaper

Clearly, cash is on its way out the door. Of course, small business owners want to open their doors to as many customers as possible.

But many worry about complex sign-ups as well as pricey set-up fees, monthly costs and minimum spend charges that were once a staple of traditional point of sale systems or PDQ machines.

Yet our investigation into the cheapest mobile card readers found that many of these complicated costs no longer apply, thanks to the rise of fintech former start-ups that are now giving the big banks a run for their money.

Today, leading companies like Square, iZettle, and SumUp have already taken over the payment processing giants to become the most popular option for the UK’s small businesses, and they all tend to have no lock-ins and no monthly or set-up costs.

You just pick up a card machine for as little as £30 today, then just pay a flat fee (1.75% on average) per transaction.

3. Card machines can grow sales

What’s more, the small business owners and entrepreneurs we spoke to – from Hilda Valerie florists to Maxwell Scott luxury leather goods – saw a boost in sales and ROI well beyond any costs involved.

Taking care of your business often means giving your customers what they want, and with mobile card payments now cheap and easy, there’s little reason not to.

The well-rated Square app has more features than any other, and can even be used to keep a record of cash and cheque payments.


4. PayPal: For instant transfers

PayPal Here

Most of us know PayPal as a global e-commerce provider.

The company first launched its PayPal Here card reader here in 2013 to target small businesses such as taxi firms and market traders that traditionally rely on cash payments.

Since 2013, PayPal Check in has been helping customers ‘log in’ to businesses, and make payments using just their mobile phones through the PayPal app.

  • Device cost – £65 or £45 on offer here
  • Transaction fees – 1% – 2.75%, depending on your monthly sales
  • Minimum spend – £0
  • Cards supported – Visa, MasterCard, Maestro and American Express, contactless cards as well as Google Pay and Apple Pay. PayPal Here is also compatible with the PayPal Check in app
  • Compatible devices – iOS 8.1 and later, select Android smartphones
  • Settlement time
  • Refunds? – Yes, refunds are easy using the ‘sales history’ feature on the PayPal Here app
  • Receipts? – Yes, by email or text

PayPal has the cheapest transaction fees for businesses with high sales volumes, but if not (and the instant settlement times don’t do it for you) you can get a better rate with one of the others.

This table breaks down the PayPal’s transaction fees, based on your monthly sales volumes:

Monthly Sales Transaction Fees
Under £1,500 2.75%
£1,500.01 – £6,000 1.75%
£6,000.01 – £15,000 1.50%
£15,000.01 – £25,000 1%
Over £25,000 Custom rates

Once you pair your phone or tablet with the PayPal Here card machine via Bluetooth, you’ll be able to start taking card payments right away.

And don’t worry – your customers don’t need a PayPal account to use this mobile card machine – it works just like any other.

The PayPal Here app has all the features you need, but the most useful ones are letting you check the status of a payment, and check in on your sales.

The card reader can also log cash and cheques, as well as send e-receipts and invoices.


How to choose a mobile card payment provider

The rise of mobile payment devices means that it’s never been easier – or cheaper – for small businesses to accept card payments – whether you run a shop, market stall or face-to-face service. But that doesn’t make picking the right one for you a simple task.

Here are the three top tips to help you pick a good’un:

  • Watch the transaction fees – These days, set-up costs are rare and card machines are cheap. It’s the transaction fees you really want to compare
  • Compare payment delay times – Transfer times aren’t always instant, as card payments are processed and authorised securely through a merchant account. PayPal settlements often have no delay, but others can take between one to three business days
  • Check for card encryption – There are a number of real-time checks in place to make taking card payments air-tight for you and your customers

For peace of mind, we made sure all the mobile card payment solutions we recommend adhere to the golden standard of the global Payment Card Industry Data Security Standard (PCI DSS) to keep you secure.

That way, taking cashless payments can be as pain-free as getting cash in the hand.


Card payment apps

All the mobile card machines on this page come with an easy-to-use and well-rated app on Google Play or the App Store.

These apps are the brains that allow you to process card transactions quickly and simply with a user-friendly interface for your smartphone or tablet.

In most cases, your device will connect to the card reader wirelessly, although wired options are also available.

A card payment app is a lifesaver for modern businesses in need of intuitive software. These apps offer a range of features that will help streamline and speed up not only taking payments but also tracking them.

Here are the main reasons small business owners turn to mobile card payment apps:

  • Easy-to-use – Card payment apps are built to make your life easier, and iZettle and PayPal have two of the top rated apps for design
  • Quick – Sending money with mobile devices is quicker than having your customers fumble through their bags for cash, and replaces cash drop offs at the bank
  • Secure – Just like your mobile banking, card payment apps are designed to be secure, both for you and for your customers
  • Flexible – By nature, card payment apps are the most flexible payment option – you can process payments anywhere there’s internet, any time

Smart payments are on the up year on year, and Forrester Research estimates that over £26bn of in-store purchases happen using mobile devices.

In the same way you use mobile banking apps to check your personal funds and accounts, most card payment apps provide live sales updates, and will do the legwork of the accounting for you.

Here are our three top questions to see if you’re ready:
