NEW TAIPEI CITY, TAIWAN – [September 23, 2026] – Castles Technology (TWSE: 5258), a global payment solutions provider, today announced a major milestone in its SoftPOS development, achieving PCI Mobile Payments on COTS (MPoC) validation across MPoC Software, MPoC Attestation and Monitoring (A&M) Service, and MPoC Solution.
One MPoC Architecture, Multiple Paths to Market
The validated components are as follows:
- MPoC Software – Flexible SDK Integration
Castles Technology’s isolated MPoC SDK, listed as part of its validated MPoC Software, can be integrated into existing merchant or business applications, enabling partners to maintain control over their branding, user experience, and business workflows while building their own SoftPOS solution.
- MPoC Attestation and Monitoring (A&M) Service – Simplified Security Operations
Castles Technology’s listed MPoC Attestation and Monitoring (A&M) Service provides the backend security monitoring capabilities required to support an MPoC environment, covering device attestation, security monitoring, and risk assessment. By hosting and operating the A&M service infrastructure, Castles Technology enables partners to deploy MPoC solutions without building and managing the monitoring backend independently.
- MPoC Solution – Faster Time to Market
For organizations seeking a complete deployment model, Castles Technology provides a validated end-to-end MPoC solution that reduces development and integration requirements and accelerates commercial rollout.
Building a More Flexible SoftPOS Ecosystem
As payment acceptance continues to move beyond traditional payment terminals, Castles Technology’s modular MPoC portfolio enables acquirers, gateways, PSPs, and ISVs to choose the deployment model that best fits their technical and business needs. Whether building with Castles Technology’s SDK, operating with its A&M service, or deploying a complete MPoC solution, partners can accelerate SoftPOS adoption and deliver secure, scalable payment experiences across a wide range of use cases.
