Unattended payment platforms comprise several integrated elements.

• Hardware: This encompasses the physical devices utilized for payment acceptance, such as card readers, contactless terminals, and cash acceptors. Prominent manufacturers, such as PAX, specialize in producing robust and secure hardware, often accompanied by Software Development Kits (SDKs) for seamless integration with other platform components.
• Software: This software facilitates communication between the payment hardware and payment processor, ensuring secure transaction authorization and settlement. POS Software with MDB, Pulse, and USB Protocols: This software functions as the central processing unit of the unattended terminal, managing sales, inventory, and customer interaction. Crucially, it utilizes communication protocols, such as a Multi-Drop Bus (MDB), Pulse, and USB, to connect and control various peripherals, including kiosks and other automated retail devices.
• Telemetry Software: This software provides remote monitoring and data management capabilities, enabling businesses to track sales, inventory levels, machine health, and customer behaviour in real time.

The unattended payment market features a diverse range of entities including:

• Payment hardware Providers: Companies such as PAX focus solely on developing and manufacturing payment hardware and associated SDKs.
• Payment-Acquiring and Processing Providers: These companies specialize in constructing infrastructure for secure payment processing and offer a variety of solutions for accepting electronic payments.
• Complete Self-Service Platforms: These providers offer comprehensive solutions, integrating POS software, payment processing, and telemetry systems into a single, unified platform.
