FAQs
What is the best card machine for independent opticians in the UK?
The best UK card machine for independent opticians in 2026 is Square Terminal on Square. Practice-management integration matters more than rate: check that your practice software (Optix, Acuitas or similar) connects to Square before signing. Card-on-file for lens-subscription billing handled on the same stack.
How much does a card machine cost for independent opticians?
Hardware runs from nothing (Tap to Pay on iPhone, on a phone you already own) to £229 + VAT (Stripe Reader S700), with SumUp Solo at £79 + VAT and Square Terminal at £149 + VAT. Published pay-as-you-go rates on UK cards are 1.69% at SumUp, 1.75% at Square and 1.75% at Zettle, with no monthly fee; contract providers quote a blended or bespoke rate and usually charge monthly terminal rental instead. Your blended monthly cost depends on card volume and average transaction size, so model it on your own numbers with our fees calculator rather than relying on a flat figure.
What is the average transaction size in this trade?
£60 to £400+, on our working estimate. Your own card statements give the real figure, and it matters because percentage fees and fixed per-transaction fees weigh differently on small and large payments.
How much contactless use is typical for independent opticians?
Lower, with larger payments by chip and PIN, on our working estimate. Your own card statements show the real split between tap and chip and PIN, which is worth checking before you choose between a phone-paired reader and a standalone terminal.
What should I watch out for when choosing a card machine for independent opticians?
NHS GOS voucher reimbursement runs separately from card-acquirer flow. Also check the contract length, exit fees, chargeback handling and how quickly money settles into your account.
How we rank
Rankings are built by desk research from each provider's published rates, upfront costs, contract lengths and settlement terms, held in a dated record per terminal (last-reviewed date shown on this page) and re-checked when published pricing changes. We do not hands-on test every device; specs are taken from provider documentation and cited. No provider pays for inclusion or position. MerchantHQ is an introducer. Quote enquiries go to one card-payments broker, Merchant Advice Service, which pays us a fee for each introduction; acquirers do not pay us commission on quote enquiries. That fee never affects a ranking. See our methodology and how we are funded.
