What Are the Best Mobile Card Readers in 2019? 

Contactless card readers are the preferred choice among many small and start-up businesses nowadays. They are simple and easy to use, they come at affordable prices, and can easily replace traditional card machines, which are more complex to both use and set up.

Processing payments has never been easier, and the ‘mobile’ part of these machines allows for transactions almost anywhere at any time. There are countless mobile card machines on the market, so it is imperative that you evaluate each and find the one that suits your business the best.

Some mobile card machines require you to also make an agreement with a merchant account provider, to further enable secure transactions. If you are interested in these types of card readers, check our article on the best providers of merchant account in 2019

By comparing the most important features of the three different card payment machines for small businesses, it is evident that depending on the requirements, they are all great options, especially with low setup costs and no monthly fees. When comparing their original prices, SumUp Air Reader and Square Reader come at a lower price than the iZettle Card Reader 2, however quite frequently, the card readers are offered at a much lower price. Check companies’ websites for more details.

Transaction fee of 1.69% is the lowest with SumUp, while the other two charge a fixed price for all types of transactions, a fee of 1.75%.

All three brands offer a mobile card reader that works together with iOS and Android apps for processing the payments. When it comes to the card types accepted, you get more options with iZettle and SumUp, but Square is not far behind, as it accepts all major card types. However, from the three, iZettle accepts the widest variety of cards.

On top of card payments, users are also able to pay contactless through payment services on their phones. The two most used services Apple Pay and Google Pay are available for all three card processors. However, Samsung Pay is not an option for the SumUp card reader, but is available for both iZettle and Square card readers.

Battery life is quite important for devices like these, as they need to perform at all times. Although all three card readers have long-lasting batteries and are able to get through many transactions, iZettle card reader is built with a new powerful battery, promising to hold 30% longer than any other mobile card reader battery on the market.

Hence, if battery life plays a big role in your choice, there is no doubt that the iZettle Card reader is the best option for your business.

The placement of pin entry can also affect your decision. As you can see in the picture above, SumUp Air Reader and iZettle Reader 2 allow for the customer to enter their pin directly on the reader. Square Reader on the contrary doesn't have this feature, and the customers need to enter the pin on the smartphone/tablet.

Depending on the business and how the card reader is intended to be used, there are extra accessories and features that can be purchased for additional fees. From receipt printers and scanners, tablet stands, cash drawers, to analytics and administrative tools, all three brands offer a variety of additions for a full mPOS (mobile point-of-sale) system. With all the three card readers, receipts can be sent through SMS, email, or can be printed.

The design of all three different mobile card readers is very slick and modern. However, so far, only iZettle card readers come in both black and white colours. The rest only come in white for now.

Lastly, we have compared the three card readers in terms of tipping options. Only the SumUp card reader doesn't allow for tipping – iZettle and Square have implemented this in their products. Thus, if you are in the restaurant industry, for instance, this is something to keep in mind.

SumUp Card Readers Review  The Right Choice for Your Business?

SumUp is one of the leading electronic point-of-sale (ePOS) companies in Europe. They have built their own payment solution end-to-end, and are also working on developing a suite of APIs and SDKs in order to implement SumUp payment into other apps and services.

There are currently two card readers offered by SumUp: SumUp Air Card Reader and 3G Card Reader.

What Is the Difference Between SumUp Air Card Reader and 3G Card Reader?

Although SumUp Air is created to be one of the most advanced devices in its category, with the 3G Card Reader SumUp has gone a step further in creating a unique device that has some features that we haven’t seen in other card readers before.

The original SumUp Air Card Reader works accompanied by a smartphone or tablet. Hence, the owner enters the amount on the mobile/tablet, and the customer can proceed with the payment using a card, contactless, or through mobile payment services.

With the new 3G Card Reader on the other hand, some of those steps are skipped. Only one device (the card reader) is used for the payments. All you need to do is to enter the amount directly on the device, tap the ‘charge’ button, and allow the customer to pay with the preferred method. All the payment methods are available here as well (chip, contactless, or mobile payment services).

SumUp Air Key Features

  1. OLED Display
  2. NFC antenna
  3. EMV chip reader
  4. Powerful battery (500 transactions)
  5. Accepts chip, contactless and mobile payments.
  6. Connects to your smartphone/tablet via bluetooth.
  7. Connects to the internet through WI-FI.
  8. Micro USB charging port.

  7. Connects to a 3G network through a built-in SIM card.
  8. Micro USB charging port.

 

As the name indicates, the biggest novelty of the 3G Card Reader is that it automatically connects to a 3G network via built-in Sim card (no data costs). It was launched in 2018, and is the first and only card reader on the market with this feature for now.

The new SumUp card reader costs £99. It is clearly a higher price, however expected, with all the new features that come with it. Transaction fee is the same for both card readers.

Safety plays a huge role when it comes to any kind of payment. iZettle focuses a lot on providing customers with a product that fulfils the highest security requirements and industry standards.

For this reason, they have removed the magstripe and added features such as transaction protection, payment data encryption, and a tamper-proof design. This makes the iZettle Card Reader the most well-protected payment machine on the market.

Lastly, iZettle has made the iZettle Reader 2 available in two colours, which is new when it comes to this type of card reader. So far, we have only seen white mobile card readers.
