How SumUp Solo works

SumUp is known for its user-friendly, simple card payment solutions for small businesses and sole traders alike.

The latest card terminal, SumUp Solo, is a special one: a square-shaped, standalone card reader without a physical PIN pad. Instead, it is operated exclusively via the front-facing touchscreen, like a purpose-built mobile device for card payments.

Accepted cards

The card reader comes with a built-in SIM card with unlimited data for 3G connectivity, but can also function through WiFi.

It is therefore ideal as a mobile card terminal that works on even low network connections, as well as for table-service in, for example, a small café with a secured WiFi network.

To accept a card payment, you enter an amount and custom description on the screen, proceed to add a tip (if relevant), process the card and send a digital receipt. Transactions can be viewed and refunded on the terminal.

Solo accepts a wide selection of chip and PIN and contactless cards and mobile wallets.

Payments are automatically settled in your bank account within 1-3 working days, or the next day (including weekends) in an online SumUp account linked to a SumUp Mastercard that is free to use.

It is free to refund card transactions, as long as the transaction has not yet been settled in your bank account (i.e. within 1-3 days of the original transaction). After that, SumUp will charge a 1.69% transaction fee to process the refund.

If a customer disputes a payment, a chargeback fee of £10 occurs.

Terminal features

SumUp Solo is a totally unique card terminal to enter the UK market. It is the first card machine 100% designed by SumUp in-house by a team of over 100 engineers and product designers. Previous card readers – such as SumUp Air – were partly designed by SumUp, using certain hardware components by third parties.

And the result? A simple touchscreen terminal that can constantly evolve with software updates. It is comfortable to hold in your hand, lightweight and easy to slide into a pocket. The built-in software is quite basic at this point, but SumUp may add features down the line.

The (non-colour) touchscreen is highly responsive. When it’s on standby and not in the accompanying dock, you simply tap the dark screen to show the checkout screen. If stationed in the dock, you have to press the power button on the side to activate the screen.

Solo’s display in strong sunlight.

You can adjust the screen brightness to suit any environment and set it to turn off the screen after 30 seconds, 1-5 minutes or never.

We tested the maximum screen brightness in strong sunlight, and the screen was still readable. However, it was grey and not bright in the sun – though better than the performance of SumUp 3G’s display that has had complaints about being hard to see in the sun.

The battery life is officially 100 transactions from a full charge, but in reality, it depends a lot on how it’s used.

With maximum screen brightness and frequent testing, the battery did not take more than an hour to use half its power. If you only used it for transactions, with low screen brightness, it would last longer. It also drains the battery within hours to keep it on standby.

It takes a few hours to charge Solo from 0% to 100% – not quick, so you should always make sure it’s got enough power when it’s most needed.

What about the software? Here are the features:

  • Checkout screen: Numerical keypad where you enter a transaction amount and custom description to go on the receipt. You cannot enter multiple amounts for one bill or add products from an inventory library.

You can only enter one amount per transaction.

Entering a transaction description can be fiddly with big fingers, as the keys are small.

  • Digital receipts: After each successful transaction, you can send a receipt via email or text message (it’s all free).

  • Tipping: Turning on ‘Smart Tipping’ will display tipping suggestions before each payment, which has been shown to increase your tipping income. The customer can either choose a tip like £2 or 15% (depending on transaction value), add a custom amount or choose not to tip.

  • Connections: Toggle on/off WiFi and log into your WiFi network from the main menu. If it’s switched off, the terminal will use its SIM card to connect with the best available mobile network.

  • Sales history: View your transaction history on a list, sorted into dates. Tapping on a transaction gives you more details about the transaction, and options to refund or resend an SMS or email receipt.

  • Languages: Set the language to almost any European language. This is useful if you’re going on a business trip abroad (SumUp Solo can be used abroad under some circumstances) or serving non-English-speaking clients.

That’s it for features. You cannot connect the terminal with a point of sale (POS) app or add more features, but SumUp may decide to add new functions through its regular software updates. For instance, we experienced a sudden increase in language options from one day to another while testing.

The card machine automatically shows when new updates are available, but you can also check software updates manually on the terminal. If you need to, you can log out of the SumUp account from the settings menu (you must log in with your SumUp account details the first time you use it).

Accessories and printed receipts

Since this is a standalone card machine, there are not many accessories to connect it with.

The main accessory – included in the package – is a non-slip display stand to put on a countertop. This doubles as a charging dock with an internal storage compartment for a USB charging cable.

You can either plug the charging cable into Solo directly, or place Solo in the cradle and plug the cable into the dock to charge the card reader. You’ll need your own adapter plug for the USB cable, or charge it through a USB charging socket.

The dock’s clear, magnetically attached lid is a great, stylish protection to keep the reader free from dust and dirt. The included decals showing all the cards accepted by SumUp Solo can be stuck onto the lid perfectly.

With the lid off, chip cards can be inserted.

What’s lacking is the possibility to attach a receipt printer. However, SumUp will later in 2021 release a special receipt printer to connect with Solo. In the meantime, SumUp 3G and Printer and SumUp Air with a compatible Bluetooth printer can be used for paper receipts.

You cannot connect Solo with point of sale equipment like a cash drawer, barcode scanner or kitchen printer. It is meant purely for card and mobile wallet transactions, not cash or POS setups where you scan products or print itemised receipts.

SumUp Solo vs. Air

If you’re facing a choice between SumUp Air and SumUp Solo, there are some crucial differences.

For a start, SumUp Air only works when it’s connected with SumUp App on a phone or tablet connected to the internet. Solo only works on its own.

Because Air is only switched on when a transaction created in SumUp App is ready for the card payment, the battery life of Air is much better than Solo at 500 transactions from a full charge. Transactions on Solo are created from start to finish via a power-consuming touchscreen, so it only lasts 100 transactions from a full charge.

SumUp Air can connect with a good range of compatible, mobile receipt printers over Bluetooth. Solo cannot yet connect with a receipt printer, but SumUp is developing one that fits specifically with Solo.

Size-wise, Solo is a bit smaller and lighter than Air. This is somewhat due to its dominating touchscreen that acts as both the display and keypad in one, whereas Air has a separate display and physical PIN pad below.
