Welcome

Welcome to the Aera In‑Store Payments documentation.

Aera provides payment terminal and in‑store payment solutions that enable merchants, POS vendors, PSPs, and platform providers to build integrated payment experiences across physical retail environments.

This documentation covers everything needed to design, integrate, and operate Aera in‑store payment solutions, including:

• Terminal integration APIs
• Payment flows and transaction handling
• Authentication and security concepts
• Technical architecture
• Terminal configuration and deployment
• Operational and troubleshooting guidance

Whether you are integrating a POS system, connecting payment services, or deploying payment terminals in stores, this documentation provides the information required to get started.

Let’s build something that’s not just functional — but transformational.

Built for Unified Commerce

Aera In‑Store Payments is designed as part of a unified commerce platform, where in‑store payment experiences are connected with the broader commerce ecosystem.

Using shared payment infrastructure across channels enables merchants to:

• Reuse payment capabilities across physical and digital channels
• Maintain consistent payment and customer experiences
• Simplify operations, reporting, and payment management
• Support centralized payment routing and PSP connectivity

Rather than treating payment terminals as isolated store devices, Aera integrates terminals, POS systems, and backend services into a unified commerce architecture.

What You Can Build

The Aera platform supports several in‑store payment models, including:

• POS integrated payment terminals
• Semi‑integrated payment solutions
• Stand‑alone terminal deployments
• Customer identification and membership flows
• Voucher and loyalty integrations
• Multi‑acquirer and multi‑PSP payment routing

The platform is designed to support both small deployments and large enterprise retail environments.

Who is this documentation for?

This documentation is intended for teams involved in the design, integration, and operation of in‑store payment solutions, including:

• Merchants operating physical stores
• POS / ECR vendors integrating payment terminals
• System integrators deploying in‑store payment solutions
• PSPs connecting to Aera‑enabled terminals and store systems
• Retail IT, architecture, and operations teams

Each role may interact with different parts of the in‑store ecosystem, but this documentation provides a shared foundation for understanding how the pieces fit together.
