PayPal Here Expert verdict FAQs Expand These days, a business needs to take card payments in order to thrive. Luckily, you can do so easily with an mPOS solutionmPOS (mobile point of sale) is a type of portable EPOS system, with your smartphone or tablet acting as the register. An mPOS system enables you to take payments on the go, making them ideal for pop-up stores, market sellers, home service businesses, and food vans.An mPOS solution consists of your mobile device, card reader, and POS software. These three parts allow you to input, take, and process a transaction – you’ll even be able to keep track of your transactions, and analyse sales data collected by your point of sale software.‘Tap-and-go’ culture has become an integral part of the payment industry, with people leaving cash behind and paying by card for sums that may total no more than a couple of pence.Thanks to mobile POS solutions, businesses can start accepting and processing card payments easily, and for an extremely low price. This is because you already own one third of the system – your mobile device. How does mPOS work?As we’ve already mentioned, an mPOS system is a system that combines your mobile device, card reader, and POS software. But how does it all fit together? Purchase a card readerDownload the supplier’s POS software onto your mobile device Use Bluetooth to connect your phone to the card readerThe card reader will automatically sync up to the softwareStart taking paymentsThat’s it! You can literally order your card reader, and start taking card payments using your mobile point of sale system moments after you receive it. It’s important to note, however, that most mPOS suppliers will charge you a per transaction fee. This means for every transaction you make, the supplier takes a small percentage. This is exactly the way in which a merchant account from a credit card company (such as Visa) would work, too. A transaction example:A customer purchases a spicy chicken wrap and a soft drink for £10. In this example, let’s say your mPOS supplier charges a transaction fee of 1.75%. That means for every £10 you take, your mPOS supplier takes 17.5p.So, would you rather have your mPOS supplier take 17.5p, or lose out on a £10 sale because you’re not taking card payments?We know which way we’d rather have it!

The card reader costs £29 (+VAT) and connects to your mobile device using a wireless or 4G connection, and collects sales information that’ll help you keep track of trends.

SquareBest for customisation While Square may be pushing it a little when it comes to credit card fees, it more than makes up for it with its powerful software system and card reader costing just £29 (+VAT). Square’s software is highly customisable, which means you can make it work for you – whether you own a restaurant or retail business. Its next best feature is its dashboard, which provides you with heaps of useful sales data. Pair this with Square’s in-built customer management system, and you’ll soon see your sales figures rising. 3. WorldpayBest for scalability Worldpay is the world’s biggest payment processing provider, with over 26 million transactions processed everyday. But why is Worldpay so popular? Firstly, its system is secure, rigid, and refined – you’ll benefit from fraud protection, fast payouts, and all manner of sales data. Secondly, its hardware package is very good as well, but its card reader does cost more than iZettle's and Square's, costing £69 (+VAT). Its card transaction fees are also higher, ranging from 1.95% to 2.75%.My Business Hub is an all-in-one solution that includes a cash drawer, printer, and bar scanner – ideal for growing businesses.

But it does have something up its sleeve to sway you in its direction – its low credit card processing fee of 1.69% with zero monthly or hidden fees. This low fee is very attractive, and one that small businesses should certainly take note of. However, SumUp’s software features are limited – and with scaled down reporting and no in-app invoicing, you do have to consider how this may affect your business in the future.
