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.

Take your trade. We do the rest.

Named UK account team for the life of the agreement. Acquirer pays our commission on completed introductions, so it costs you nothing on top.

24/7 dedicated support
Direct line to a named UK account manager, not a generic acquirer helpline. When your terminal goes down on a Saturday night you call us.
Quarterly rate reviews
As your card volume grows your rate should drop. We renegotiate against the 80+ UK acquirer panel every quarter, so you never overpay because you forgot to ask.
Chargeback and dispute help
UK chargebacks cost £15 to £35 per case and 60-80% are friendly fraud you can win with the right evidence. We draft the response and escalate where the acquirer drags its feet.
Switching support when you outgrow
If a better acquirer fit emerges as you grow we manage the cutover. No exit-fee surprises, no dual-running gap. Same account team across acquirers.
