ATOM

ATOM is Payrillium’s unified payment engine designed to support every merchant integration model. Whether you operate standalone terminals, embedded POS systems, cloud-native platforms, or custom applications, ATOM provides a single secure API and scalable architecture to deploy anywhere.

Build once. Deploy anywhere.

ATOM uses a single secure API across Standalone, POS, Semi-Integrated, Cloud, and App-to-App modes. That means no rewriting code when your customer moves from local POS to cloud orchestration, kiosk, or embedded commerce.

One Core. Multiple Deployment Models.

Atom offers several flexible modes of operation, allowing merchants to adapt the payment application to their specific business needs, hardware setup, and integration requirements. All modes run within the same unified Android-based app from Payrillium, ensuring consistent security, ease of use, and access to features like PayLove for personalized customer messaging.

POS Mode

Transforms the terminal into a lightweight POS system with product management and real-time sales tracking.

Standalone Mode

Complete terminal-native payment system with transaction lifecycle, clerk management, reporting, and branding — no external POS required.

Semi-Integrated Mode

Deploy once using HTTPS POST API. No proprietary SDK. Supports synchronous and webhook workflows.

Cloud Mode

Control devices remotely. No local server. True build-once-deploy-anywhere architecture.

App-to-App Mode

Localhost HTTP integration. ATOM surfaces only during payment and returns control instantly.

PayLove Mode

Built-in thank-you messaging, promotions, and branded experiences to drive repeat visits.
