The bottom line
If you’re looking for a card reader provider that is convenient and you know what you are getting, you can’t fault with fan-favourite SumUp. With its large range of products, you can choose the perfect one for your business. But, if you’re looking for a card provider that doesn’t sting you with a chargeback fee or a longer warranty period, there are other options out there.
However, if you’re looking for something on-the-go, the Square Reader is another great choice for SMEs, particularly with its low transaction fees. With the added feature of a phone mount, you won’t need to worry about wires or juggling machines. But the downside of this is that you have to have a connection to an additional device such as a smartphone or tablet. And if you opt for the Square Reader’s big sister, you will need to have a wifi connection, which limits how far you can take your machine.
So, Square or SumUp? The decision ultimately depends on your business’s needs and wants. You can compare the SumUp and Square range below:
