Intro - Choose Your Best Practice

We offer three integration methods:

1. Cloud API:

Quick Start - Cloud API

The Point of Sale (POS) system and the payment terminal are connected indirectly via a cloud API, with no direct physical link or requirement for the same network segment. This enables flexible integration and secure data transmission.

Advantages:

1. Flexibility and Scalability: Easily add or remove terminals and POS systems to accommodate business growth. Cloud-based solutions scale seamlessly, minimizing hardware upgrade needs.

2. Centralized Data Management: Transaction data is stored centrally, simplifying report generation, sales trend analysis, and inventory management for efficient decision-making.

3. Location Independence: Supports multi-location deployments, making it ideal for businesses with multiple branches, while maintaining a unified system without local configurations.

4. Reduced Physical Dependency: Eliminates reliance on cables and local wiring, lowering maintenance costs and enhancing system reliability.

2. Local Integration:

Payment App Integration Protocol

The Point of Sale (POS) system and the payment terminal are connected directly via USB, WIFI, Bluetooth, or a wired network to initiate transactions quickly and reliably.

Advantages:

1. Faster Transaction Speeds: Direct local connections enable quicker processing, outperforming cloud-based options in areas with unstable internet.

2. Enhanced Security: Data is transmitted locally, reducing exposure to online threats, but requires strong security measures (e.g., encryption) to address potential local vulnerabilities.

3. Internal Integration:

Payment App AIDL Integration

In the payment terminal, the business application directly invokes the AIDL interface provided by the OPC to process transactions internally on the same device, eliminating the need for external connections.

Advantages:

1. Ultra-Fast Processing: Internal calls reduce latency, enabling near-instant transaction handling without network delays.

2. Efficient Resource Use: Leverages local device resources, minimizing overhead and optimizing battery life and performance.

3. Heightened Security: Limits data exposure by keeping operations within the device, reducing risks associated with external data transmission.

4. Simplified Development: Streamlines integration for developers, as AIDL facilitates easy inter-app communication without complex setups.

In summary:

1. Local Network Connection

   • Pros:

     • Faster transaction speeds due to direct communication, ideal for environments with unstable internet.

     • Enhanced security by keeping data local, reducing exposure to external threats.

   • Cons:

     • Relies on stable local hardware (e.g., WIFI or Bluetooth signals), which can fail in interference-prone areas.

     • Potential security vulnerabilities if local connections aren't properly encrypted or managed.

2. Internal Invocation (via AIDL)

   • Pros:

     • Ultra-fast processing with minimal latency, as everything happens on-device.

     • Efficient resource use, improving battery life and performance while maintaining high security through localized operations.

     • Simplified development and integration for teams.

   • Cons:

     • Limited to a single device, making it inflexible for multi-device or scalable setups.

     • Requires advanced technical expertise to implement and troubleshoot.

3. Cloud-Based API

   • Pros:

     • Highly scalable and accessible, allowing remote management, real-time updates, and integration across multiple locations.

     • Easier to maintain and update software centrally.

   • Cons:

     • Slower processing times in areas with poor internet, potentially disrupting transactions.

     • Higher security risks due to data transmission over the internet, increasing exposure to breaches.
