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.
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.
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.
Explore EMV capabilities →Turnkey, hardware-agnostic platforms for vending, EV charging, parking, petroleum, and car washes. Certified stacks on PAX, Ingenico, and Verifone, with MDB integration and field-ready Android terminals engineered for uptime.
See unattended platforms →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.

Turnkey products you can white-label and resell. Start small on existing hardware, brand it as your own, or build a full platform — the commitment scales with your ambition.
Unclear synthesizes every payment signal into one explainable decision. Five scoring lenses run across your settlement files, returning a score, a band, and the plain-language factors behind it, so your team acts on reasoning it can defend, not a black-box number.
Unclear is Transaction Intelligence for payments teams: ISOs, ISVs, processors, and acquirers. It reads the transaction exports you already produce, scores each row for fraud, and shows the reasoning behind every number, plus how suspicious transactions link into rings. It runs as an analysis layer after the transaction, never in your authorization path. It scores and explains; it does not move money.
Paying.co builds its own products, then exposes them through native MCP servers. Puny, Landed, and Ask aren't just tools you use — they're tools your AI can operate directly. Publish a page, shorten a link, or send a payment request, straight from the conversation.

A live, AI-powered window into your project. From kickoff to launch, you get near real-time insight into progress, milestones, and what's next — so you always know exactly where things stand while we're working together.
flaw.co scans your public attack surface and gives you a letter grade instantly. When the grade exposes real risk, Paying.co's senior pen testers take over with the full engagement — internal segmentation testing, manual exploitation, and QSA-ready reporting a scanner cannot produce on its own.
Passive scan of TLS, HTTP headers, exposed services, and information disclosure. Instant letter grade and unredacted findings at no cost.
