At UK Card Readers, our mission is to help small business owners and sole traders make confident, informed decisions about how they take payments. To support this site and keep our reviews free and independent, we sometimes use affiliate links.

This means that if you click on a link to a product — such as a card reader from SumUp, Zettle by PayPal, or Square — and go on to make a purchase, we may earn a commission. This comes at no extra cost to you.

We only recommend products we’ve personally tested in real UK business environments, including shops, mobile services, events, and market stalls. Every recommendation is based on honest evaluation, not paid placement. We do not accept sponsored posts, and we never rank products based on affiliate commission.

We believe in full transparency — so if you ever have questions about how we test products or how affiliate links work, you can always get in touch.
