What is the difference between a card reader and a card machine?
There is no difference. "Card reader", "card machine", "card terminal" and "PDQ machine" all describe the same thing: the device a customer uses to pay you in person by tapping, inserting a chip card, or holding their phone against it. Fintech brands (SumUp, Zettle, Square, Tide, Revolut) say "card reader"; older bank-acquirer documentation says "card terminal" or "PDQ". Same device.
What is the best card reader for a small business in the UK?
SumUp Solo is the strongest all-round pick at £99 hardware, 1.69% flat, no contract and a free 4G SIM. For an all-in-one with a built-in printer, Square Terminal at £149 is the better fit. The cheapest entry on hardware is Zettle Reader 2 at £59. If you already bank with Tide or Revolut, their £49 readers carry the lowest rates (1.5% and from 0.8%).
How much does a card reader cost?
Hardware runs from £49 (Tide, Revolut) to £329 (Stripe Reader S700), with most readers between £59 and £149. On top sits the rate per transaction, from 0.74% (Tyl by NatWest, for NatWest customers) to 1.95% (SumUp at its lowest plan), and usually no monthly fee on no-contract readers. Tap to Pay on iPhone needs no reader at all if you have a compatible iPhone.
Do card readers need a phone or do they work on their own?
It depends on the reader. Standalone readers (SumUp Solo, Square Terminal, Stripe Reader S700) have their own screen and connectivity and work without a paired phone. Tethered readers (Zettle Reader 2, Tide, Revolut) pair to your phone or tablet over Bluetooth and use the app, which makes them cheaper but dependent on your phone. For unreliable signal, choose a 4G standalone reader.
Which card reader has the lowest fees?
On headline rate, Revolut Card Reader (from 0.8% on higher Revolut Business plans) and Tide Card Reader (1.5% for Tide Business customers) are lowest, both conditional on holding that business account. Tyl by NatWest publishes 0.74% for existing NatWest customers. Among unconditional no-contract readers, SumUp Solo (1.69%) is competitive for sub-£10k monthly volume.
