Two providers: two card each. Here’s what you need to know.

Zettle Reader 2
Compare rates and fees
One of the most important things to look at when you’re comparing card readers is the difference in the rates and fees each provider charges: not just the headline cost of each product, but the more ‘hidden’ fees too. For further explanations of the different charges you might come across in your research, use our handy guide.
The Square Reader and the Zettle Reader 2 have identical transaction fees of 1.75%, but the upfront cost of the Zettle model is £29, compared to the Square Reader’s £19.
Compare features
They’re very similar products: small card readers suitable for use on the go.
However, one big difference is in the battery life: while a fully charged Square Reader should keep going all day, the Zettle Reader 2 can only handle around 100 sales. A charging dock will set you back an extra £39.
For a full insight into the different features you should look out for when comparing card readers, you can use our helpful guide.
The bottom line
They’ll cost you less and they’ll last longer before needing to be charged: Square’s products win out as far as we’re concerned. Don’t just take our word for it, though: compare the full ranges below before you choose the best card reader for your business.
