Square Reader – Full Review


The Square card reader is a combination card reader and app that allows anyone to easily accept card and mobile payments without the need to set up a merchant account.

Furthermore, its simplicity of use, invoicing function, flat rate fee and affordability have made it a popular choice for individuals and businesses alike.

In this review we take a look at the functionality, costs, its competitors, pros and cons,  and important aspects such as security and ease of use.

So let’s just dive right in.

What is the Square Card Reader [UK]? 

Let’s get to the point.

The Square card reader is, as the name suggests, a method by which a person or business can accept debit and credit card payments.

Fact is, it supports chip and pin, contactless and mobile payments, and also features an app that’s compatible with both Android and Apple. But it doesn’t stop there…

Some of the other key benefits of Square are:

  • Accepts Visa, Mastercard, American Express and most major international cards
  • No need to set up a merchant account
  • Payments are processed in real time and the funds deposited in your bank account the following day
  • Simple, fast set-up that allows you to accept card payments within minutes
  • Accepts payments in-person, online, over the phone and via invoice
  • No set up or monthly fees. Each payment incurs a simple transaction fee
  • Includes full reporting and analytics
  • Includes an app based Point of Sale (POS) system
  • Integrates with eCommerce stores


Can anyone get a Square Card reader? 

Yes. A Square card reader makes it possible for any business or individual to accept payments via debit or credit card. It’s that simple.


Is Square good for small businesses? 

Yes. Square is a good choice for a small business, especially if you don’t want to sign up for a merchant account.


Whilst such merchant accounts can allow for card payments at a lower transaction fee than that of Square’s (1.75% for debit cards), they often come with monthly fees and a tie in period.

The result?

For small businesses that take less than £1,000 per month in payments (or ones that take a lot of credit card payments), the Square option is currently one of the most cost-effective on the market.

What about bigger companines?

For high volume users a merchant account with lower transaction fees and a monthly fee might offer better value.

However, the fact that Square offer an extremely clear pricing structure and no commitment to a contract makes it a viable option for businesses of all sizes.


Is it possible to use Square without a reader? 

Yes, by keying in card numbers to your mobile device or by using the Virtual Terminal on a computer. However, to accept contactless, chip and pin, or mobile payments you do require the reader. 


Square – Costs and Fees

What does it cost to use Square? 

The basic Square system only requires you to purchase the Square card reader to get started. This currently retails at £29.00 (+ VAT) and can be purchased via the Squareup.com website.

What else must be considered?

  • A flat rate transaction fee of 1.75% for a chip and pin, contactless or mobile payment. The fee is the same for all major cards
  • Typed in card payments (for example, over the phone) or by using the invoicing facility or eCommerce payments attract a 2.5% fee

Transaction fee – virtual terminal2.50%


Is there a monthly fee for Square?

How do Square’s fees compare with its competitors?

All in all, Square’s main competitors are:

It turns out, SumUp charges a flat fee that’s slightly less than that of Square, at 1.69%. However, they hold onto your money for longer, paying out to your bank account in 2-3 days.

iZettle charges the same 1.75% fee per transaction as Square and deposits funds in 1-2 days.


How does Square work?

One of the biggest plus points about Square is its simplicity. The Point of Sale app is the heart of the product, and can be downloaded to your phone or tablet.

You’ll be glad to know it’s easily customizable to your business needs, and your customer can pay via contactless, chip and pin or a mobile payment method. You also have the ability to create and send invoices and to fully integrate the system with your eCommerce store.

And one more thing, the funds are debited from the client’s account and deposited in your bank account the next working day.

Other features include:

  • Create either digital or printed receipts
  • Inventory management
  • Easily customise your Point of Sale with simple drag and drop
  • Store payment details for regular customers
  • Can be used at multiple locations with a single account

  • ✓ Switch between interfaces
  • ✓ Add individual products to your library and tap to add them to the shopping cart

Can I rely on them for Customer Support? 

Square customer support does, unfortunately, follow the what’s become the standard industry norm of trying to get you NOT to call them.

When using the system for the first time you get prompts that walk you through the process.

And whilst Square is rather self-explanatory to use, this is a pretty good feature.Of course, there are the ubiquitous customer support pages that cover most FAQs.

For anything else you can get help via email or by phone. However, this is only available Monday to Friday, from 09:00 – 17:00. Run into an issue outside of these hours and you’ll have to wait until the next working day.
