The Retail Technology Show 2026 (22–23 April) is fast approaching, and this year we expect the most meaningful conversations to be around how retailers turn innovation into real growth.
There’s no shortage of ideas on the RTS agenda
From connected retail, AI-driven personalisation, and elevated customer experiences, there’s plenty for tech-hungry retailers to be excited about. But making those ideas work in practice often comes down to something more fundamental: the technology at the checkout.
Payments is no longer just operational. It’s a key part of how retailers differentiate, streamline operations, and deliver better experiences. At Castles Technology, our focus is on making the shift to next generation POS not just possible, but practical.
Customer experience remains a central theme at RTS
While there’s lots of emphasis on finding the next big thing to lock customers in, it’s often the small moments like the checkout that matters most.
With our Android-based payment solutions, retailers can enhance those moments by embedding more functionality directly into the transaction:
• Loyalty and rewards at the point of sale
• Targeted promotions based on behaviour
• Faster, more intuitive checkout journeys
• Data capture and AI that feeds into wider personalisation strategies
Why Android POS remains a hot topic for 2026
Merchants want operational reliability that keeps pace with modern retail demands. Fixed tills, mobile devices, assisted selling, and self-checkout all need to work together seamlessly. That’s why Android POS has become such a powerful foundation for modern retailers.
By enabling payments to sit alongside the wider retail tech stack, Android-powered devices allow them to integrate payments with loyalty, inventory, ordering, and AI-driven tools—rather than treating them as a separate function.
Combined with premium managed services like our new CasERV offering, this approach is helping retailers across the UK and Europe to move faster and operate smarter. Giving their businesses real-time remote device management, full visibility across their estate, and proactive in the field and technical support, at scale.

Solutions built for the real world
Merchants visiting RTS are looking for devices that support their increasingly app-based environments, and tools that make it easier to build joined-up journeys across channels. Whether in-store, at a kiosk, or on a mobile device, it’s important that the experience remains seamless, even if the underlying setup differs. You can find it all at Castles Technology.
• In-store and large estates: A mix of countertop and mobile devices with centralised management and services
• SMEs and growing businesses: Mobile POS and SoftPOS for quick, low-cost deployment
• Unattended retail: Built-to-last, easy-to-integrate, POS components providing reliable performance for kiosks, transport, ticketing, and petro/EV environments
• Field operations: Devices built for mobility, connectivity challenges, and varied conditions
New POS services build continuity at scale
As POS estates grow, so does the challenge of managing them. Updates, security, and performance monitoring can quickly become resource intensive.
Castles addresses this through CasHUB, an agnostic cloud-based platform that enables remote terminal management of entire estates. Retailers and partners can roll out updates, monitor performance, and maintain security without on-site intervention.
Extending this further, our new end-to-end CasERV provides Android-powered payments, open architecture and managed services that scale on demand.
Ideal for large retailers, ISOs, and merchant acquirers, CasERV handles POS deployment, repair, estate management, and lifecycle support, reducing operational burden and improving service performance and viability. It provides the foundation needed to scale efficiently, enter new markets, and maintain consistent service levels across POS estates.
Merchants want a practical approach to innovation
Retailers don’t lack ambition. The challenge is making change manageable across complex environments.
Whether they’re looking for more accessible, secure and connected devices to improve experiences or more sustainable, efficient and cost-effective solutions to optimise business performance.
Castles Technology’s approach is grounded in that reality. We aim to deliver flexible, reliable solutions that support both new and existing infrastructure, while enabling gradual, scalable transformation that achieves merchant growth goals.
