What is the average transaction size in this trade?
£80 to £350, 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 locksmiths?
Mixed, with smaller payments tapped and larger ones 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.

MLA (Master Locksmiths Association) membership does not affect card acceptance but customers ask. 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.
