mPOS — How to Choose the Right Mobile POS System

What is mPOS (mobile point of sale)?

An mPOS or mobile POS is a portable point of sale (POS) on a smartphone or tablet that functions as a register for taking payments. A mobile POS system is an ideal way for businesses such as food trucks, home and repair services, market stalls, etc. to take credit card payments on the go.

How Does mPOS Work?

By selecting mPOS software for your business, you can download the POS app, connect your reader to a mobile device and start taking payments instantly.

Choosing the right mobile POS system for your business

When shopping for the best mobile POS for your business, look for one that is secure, easy to use and affordable.


A secure mPOS is PCI compliant, lets you take encrypted payments like chip cards and NFC payments like Apple Pay and offers chargeback protection to fight payment disputes on your behalf. (Square offers free chargeback protection on eligible chargebacks up to £250 per month, and has no PCI-compliance fees.)


Look for a mobile POS system that’s simple to use with an intuitive interface so it’s easy to get employees trained quickly.


It’s important for your mobile POS to be affordable, so make sure you know what you’ll be paying. In addition to hardware costs and the processing fee for each credit card transaction, there could be other fees to be aware of. For example, some mPOS companies charge monthly fees as well as other costs. (Square doesn’t have any monthly fees or hidden costs.)

How Square revolutionised the mPOS industry

Square started with the simple idea that everyone should be able to accept credit cards. Even now, many mobile businesses remain “cash only” because standard POS terminals are clunky and certainly not portable. Plus, signing up with a traditional credit card payment processor can be prohibitively expensive, especially for seasonal or micro businesses. Square is here to provide an alternative option.

We make mobile POS software and compatible hardware that work together seamlessly, allowing sellers to take debit and credit card payments on the go.
