Quick Start - Semi Integration
1. Local Integration:
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:
Faster Transaction Speeds: Direct local connections enable quicker processing, outperforming cloud-based options in areas with unstable internet.
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:
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:
Ultra-Fast Processing: Internal calls reduce latency, enabling near-instant transaction handling without network delays.
Efficient Resource Use: Leverages local device resources, minimizing overhead and optimizing battery life and performance.
Heightened Security: Limits data exposure by keeping operations within the device, reducing risks associated with external data transmission.
Simplified Development: Streamlines integration for developers, as AIDL facilitates easy inter-app communication without complex setups.
