Payment Engineering / Since 2018

Payments are complex.

Launching them shouldn’t take a year.

Eliminate the steep learning curve and instantly bypass your internal dev constraints. We are the elite payment engineering team you plug in by the task or project. Backed by 131+ successful EMV Level 3 certifications, we build and deploy custom apps, SoftPOS, and unattended systems in weeks, not months.

Engage us by the task or by the project. We measure ourselves by your results.

Three core services. One expert team.

Paying.co (formerly Mojave Payment Technologies) runs the full EMV L3 certification lifecycle, builds native payment apps on every major terminal, and engineers unattended platforms that run unattended. Existing acquirer relationships let us clear bottlenecks before they form.

EMV Level 3 Certification & Managed Programs

From scoping to acquirer sign-off, we run the full certification lifecycle across the US, Canada, LATAM, Caribbean, and Europe. Existing acquirer relationships clear bottlenecks before they form, so projects ship in months, not the year-plus timelines quoted elsewhere.

Custom Payment Development

We scope, design, and build in-house. C, Android, iOS, embedded, and cloud, all with payments DNA. From Clover apps and PAX terminals to multi-region acceptance stacks, we ship outcomes, not tickets.

Verdict by Paying.co Clear · Review · Decline Post-authorization review

A second look at what already cleared.

Your real-time controls are tuned to approve. Verdict is the independent pass that runs across your settlement data after the fact, scoring every transaction for fraud and showing the reasoning, so your team catches what was let through instead of combing every row.
