Best card machine for Independent opticians
Independent opticians and dispensing practices. Mix of NHS-funded sight tests, GOS vouchers and private-paid glasses, contact lenses and lens-care subscriptions.
Our pick
Square Terminal
Acquirer: Square
Practice-management integration matters more than rate. Square integrates with Optix, Acuitas and similar via partner plugins. Card-on-file for lens-subscription billing handled on the same stack.
Why this trade matters
- Cashflow shape
- Steady weekly flow with retail lumps when prescriptions are dispensed. NHS GOS reimbursement runs on a separate quarterly cycle.
- Average transaction
- £60 to £400+
- Contactless share
- ~45%
Watch outs
- NHS GOS voucher reimbursement runs separately from card-acquirer flow.
- Lens-subscription billing needs card-on-file with clear consent capture.
- Higher-value designer-frame transactions trigger SCA more often.
