Payment engineering · since 2018
Engage us by the task or by the project. We measure ourselves by your results.
The numbers behind the work.
Paying.co (formerly Mojave Payment Technologies) is a payment engineering firm that has completed more than 131 EMV Level 3 certifications for processors, acquirers, ISOs, and ISVs since 2018. We run the full EMV L3 certification lifecycle — scoping, application development, FIME and ICC test-suite execution, and acquirer sign-off — across the United States, Canada, Latin America, the Caribbean, and Europe. Our in-house team builds and certifies native payment applications on PAX, Ingenico, Verifone, Clover, and ID TECH hardware against every major acquirer specification, including TSYS, Fiserv, Global Payments, Worldpay, and Elavon. Existing acquirer relationships let us clear certification bottlenecks before they form, so projects ship in months — not the year-plus timelines quoted elsewhere.

Three recent engagements — what came in, what shipped, and how long it took. Every project ends with working software in production, not a postmortem.
An ISO out of the Midwest needed a custom payment application built on Android — from concept to a first live customer transaction. We scoped, built, and shipped end-to-end. They were taking real card payments in production faster than most shops finish discovery.
A high-growth unattended operator needed L3 certification on Sunmi hardware against TSYS Sierra. They'd been quoted seven figures elsewhere and needed it shipped in months. We built the application, ran full FIME / ICC suites in-house, and shipped with time to spare for their rollout.
A European fuel operator needed L3 certification on outdoor pay-at-pump hardware against a notoriously strict processor spec. They came to us after a third party stalled. We ran a full pre-cert pass, caught the issues their previous vendor missed, and hit the original deadline.
