Key Features

Built for APAC Requirements

Universal Terminal Support

Connect terminals from Ingenico, Verifone, PAX, and Castles Technology via a single integration — reducing the complexity of managing a mixed terminal estate.

Intelligent Routing

Route transactions to the lowest-cost acquirer in real time, with automatic fallback to secondary acquirers on failure — maximising approval rates and minimising processing costs.

Remote Terminal Management

Deploy software updates, parameter changes, and key rotations to thousands of terminals simultaneously via the TMS — without field engineer visits.

Alternative Payment Methods

Accept QR payments, digital wallets, and local APAC payment methods alongside traditional card transactions — from the same terminal and switch infrastructure.
