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: acquirers, including some brands ranked here, pay us commission on completed introductions. Commission never affects a ranking. See our methodology and how we are funded.
