Omni is enterprise payments engineering.

Bypass the sales jargon. Omni provides the direct L3 architectural framework required for enterprise-scale terminal fleets, from custom kernel development to global acquirer certifications.

EMV test cards
FastFlex™ accelerated L3 certification

Unpredictable certification, turned into a guaranteed outcome

FastFlex is Omni’s productized certification engine, designed to eliminate the traditional 12+ month industry stall. We own the entire technical lifecycle: from 8–10 page technical intake forms and toolchain configuration (UL/FIME/ICC) to real-time log triage and final LOA receipt. You provide the roadmap, and we get it done.

Plug directly into the engineering leadership

Skip the sales layers. Omni provides specialized engineering for kernel-level development, P2PE validation, cryptographic and key management engineering, custom acquirer interface engineering and everything in between, so your infrastructure is audit-ready and ready for market.

Kernel & HAL

L3 frameworks & hardware abstraction

Custom EMV L3 application development and hardware abstraction layers that bridge proprietary hardware and standardized payment kernels, in line with the latest EMVCo and PCI specifications.

P2PE & keys

Omnichannel encryption architecture

PCI-validated point-to-point encryption, tokenization, key injection facility (KIF) coordination, and PCI DSS scope reduction for enterprise merchants.

ISO 8583 / ISO 20022

Acquirer interface engineering

Direct host integration for major U.S. acquirers, mapping transaction data across ISO protocols so Purchase, Authorize, Refund and Tip-adjust flows work with zero friction.

Unified commerce

Digital transformation

Technical bridges between store systems, POS, eCommerce, OMS and CRM/WMS, supporting BOPIS/BORIS, mobile clienteling, loyalty and private-label credit in the payment flow.

Decades of high-ROI enterprise merchant engineering, compliance and digital transformation for U.S. payments technology providers.

How Omni extends your engineering depth

Bridge your legacy infrastructure to modern unified commerce with engineers who have already done it.

L3 payment application frameworks & hardware abstraction

Deep-layer engineering for custom EMV L3 application development and hardware abstraction layers for any hardware. We bridge proprietary hardware environments and standardized global payment kernels, in full compliance with the latest EMVCo and PCI specifications.

Omnichannel solution enablement & encryption architecture

We architect and support PCI-validated P2PE solutions, including tokenization, key injection facility (KIF) coordination and reducing PCI DSS scope for enterprise merchants through secure tokenization and encryption strategies.

Specialized acquirer interface engineering (ISO 8583 / ISO 20022)

Direct host-integration support for all major U.S. acquirers. We handle complex data mapping across ISO protocols so your custom implementation supports Purchase, Authorize, Refund and Tip-adjustment flows with zero technical friction.

Enterprise digital transformation & omnichannel solutioning

Architectural leadership for moving from brittle legacy infrastructure to unified commerce: one source of truth across store systems, POS, eCommerce, OMS and CRM/WMS, including BOPIS/BORIS, mobile clienteling, loyalty and private-label credit.
