1. Overview
The OctopusTMS POS SDK is an Android library that enables partner applications to process card payments through UNISWITCH-certified POS terminals. The SDK abstracts all hardware communication, EMV processing, key management, and printer control behind a clean, high-level API.
Multi-device Support
A single integration works across all supported OEM devices — the SDK automatically detects the hardware at runtime and routes all calls to the appropriate driver internally.
