DeviceMonthly rental

Is the Takepayments A920 card reader for me?

If you’re unsure about future plans for your business, the short 12-month contract offered by Takepayments is a great option, especially as the majority of competitors lock you into an 18-month contract (at least).

The A920 model is a ‘multipay’ smart POS terminal that can be shared with up to six users, which is great if you want to use it as a mobile checkout on the move around your business (great for hospitality). It also comes with a neat feature that allows you to allocate tips to each user, keeping the gratuities received within your team fairly distributed.

The fees you pay are best for high transaction values, as they can rise up to 2.5% per transaction depending on factors like average transaction value, turnover and cards accepted. There’s no setup fee or monthly cost, but be aware that if you want to cancel your contract early, you’ll have to buy out the remainder of your contract if you don’t give at least two months’ notice.

Real-time reporting and in-depth sales analysis come as standard with the A920, which is great for measuring employee performance and daily/weekly sales figures to help you identify customer trends.

Best suited for:

✓ Brand new businesses that require a short-term commitment

✓ Hospitality businesses with a high average transaction size

3. Zettle by PayPal

Is the Zettle by PayPal card reader for me?

Small businesses can use the Zettle by PayPal card reader with third party hardware, including receipt printers, cash drawers, and barcode scanners, as part of a complete POS system.

Alternatively, you can sync it up to your smartphone or tablet to take card payments on the go. Customers who require a receipt can have one sent to their email address.

The Zettle by PayPal card reader is well-suited to startups looking to take payments quickly in a no-fuss fashion.

Even its customer service is minimal, with the provider preferring to lead customers down the self-help route. For those who prefer to speak to an agent, its phone lines are only available between 9am and 5pm on weekdays.

With ultra-low costs and one of the highest rated apps around, Zettle by PayPal is a great alternative to traditional ways of processing card payments, and great for innovative and budget-conscious businesses.

Best suited for:

✓ Small retail shops and market stalls

✓ Counter service hospitality businesses, full service cafes and restaurants (with Zettle by PayPal hospitality software), pop up food stalls

Is the Square card reader for me?

Square's card reader is designed for small business owners wanting to keep costs low without missing out on the good stuff – like the option to integrate its accompanying POS software with food delivery apps or customer relationship management systems.

While unconventional, you can be reassured that Square adopts the highest security standards when it comes to developing its products.

Clean and simple, Square’s card reader adds a breath of fresh air into the payment process, and shows that it’s putting itself at the forefront when it comes to pioneering the future of the payments market.

To secure the best transaction fee rate, we suggest that you opt for Worldpay’s Simplicity plan; an 18 month contract which sees the percentage you pay per transaction drop from 2.5% to 1.5% – one of the lowest rates around.

Worldpay is for those who prioritise security over everything, so you can look forward to robust fraud protection and complete PCI compliance (security standards for processing card payments). Plus, with 24/7 support, you’ll never be left in the dark.

Whether you’re looking for a mobile card reader to take on the road, or a fixed terminal for your shop point of sale area, Worldpay’s payment taking solutions are robust options for small businesses.

Best suited for:

✓ All types of small businesses

6. Barclays Anywhere card reader

Best for Barclays account holders

Main features:

✓ Very simple functionality

✓ Fairly basic accompanying payment software

✓ Fast deposits into your business account

Barclays Anywhere pricing

Device £14.50
Card present fee1.6%

Is the Barclays Anywhere card reader for me?

Barclays’ little device accepts credit and debit card payments through the mobile connection of your smartphone or tablet. Aside from that, the card reader package from Barclays is comparatively basic.

In fact, the sole function of the accompanying software is to facilitate payments. For example, you won’t be able to upload an inventory or access an analytics platform.

You will, however, benefit from decent Barclays phone support and receive swift deposits into your Barclays account.

At 1.6%, the Barclaycard Anywhere offers one of the lowest transaction rates going, but your compromises are that the card reader only accepts Visa, Mastercard, and refunds cost 75p to process.

The Barclaycard Anywhere card reader is for those who would prefer to stick with a bank they can trust – and the Barclaycard Anywhere card machine will save you hassle if you already have a Barclays account.

Best suited for:

✓ Sole traders

✓ Small businesses that take occasional payments

The best small business card readers: the verdict

If you own a small business that’s just getting off the ground, SumUp and Takepayments A920 are the ideal first card readers. The fees are reasonable and inline with the functional capabilities of their accompanying software. Plus, Takepayments offer shorter contracts than most (12-month) and no joining or leaving fees, making it perfect for brand new business needing a zero-risk, short-term commitment.

Fast-growing businesses may want to consider Zettle by PayPal, but it’s the Square card reader and WorldPay card reader that really come up trumps (if you want to compare Square and Zettle by PayPal side by side, we’ve done so in our Square vs Zettle review).

Thanks to a vast array of third party integrations, the Square card reader offers businesses the freedom to build a payments package that works for their exact needs.

WorldPay is renowned for its security, and it offers preferential rates and packages when its pay-as-you-go fees stop becoming cost-effective.

There’s no doubt that the Barclays Anywhere card reader is the most basic out of our selection but it still has a place – particularly for sole traders who want a cheap, fuss-free way to take card payments.

If you’re still not certain about which card reader is best for your small business, the startups comparison tool is a good way to find out. Our merchant accounts team have put together a simple questionnaire that pairs businesses with the right providers based on their answers.
