Best card machine for Locksmiths
Mobile locksmiths and lockup-based key-cutters. Emergency call-outs (24/7), scheduled lock-changes, and counter-based key-cutting. Job-by-job payment.
Our pick
Tap to Pay on iPhone
Acquirer: SumUp
Mobile call-outs need zero-hardware acceptance; Tap to Pay fits. Counter-based key-cutters can add SumUp Solo for the printed receipt. No-contract economics suit the mix of emergency and scheduled work.

Why this trade matters
- Cashflow shape
- Steady with emergency call-out spikes (weekends, evenings, post-holiday). Insurance-direct work creates monthly invoice lumps.
- Average transaction
- £80 to £350
- Contactless share
- ~50%
Watch outs
- MLA (Master Locksmiths Association) membership does not affect card acceptance but customers ask.
- Insurance-direct billing for emergency call-outs runs separately from card flow.
- High-value lock replacements trigger SCA more often.
