Quick Start - Semi Integration

1. 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.

2. Internal Integration:

Payment App AIDL Integration Protocol

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.
