OSIS Payment Suite
A complete cloud-based SaaS and point-of-sale platform, built to digitise, streamline and secure the sales and payment infrastructure at large events, festivals and pop-up concepts.
Native POS architecture and haptic UX
The till app is written entirely in native Swift and SwiftUI, which gives maximum performance, full use of the hardware and a fast, reactive design driven by Apple's Combine framework.
The platform minimises till errors through a deliberate interface and uses the device's haptics to make eyes-free operation possible. A firm, confirming thump marks a correct scan or a successful server action, while a sharp buzz signals a network error.
- Reactive basket handling through SwiftUI and Combine
- Safety states prevent double-tap charges
- Rich haptic feedback (Taptic Engine) right in the sales flow
Hybrid payment engine and API security
The platform is built on an intelligent two-track routing system. To keep sales running without interruption, cash transactions are settled straight to the database, bypassing third parties entirely.
For card payments through platforms such as SumUp or MobilePay, our dedicated Node.js backend on an Ubuntu VPS acts as a security moat. It guarantees cryptographic transfer and means sensitive API keys never reach the physical iPad in the kiosk. Unlike locked-down off-the-shelf systems, OSIS Payment Suite owns the entire data flow.
- Intelligent hybrid routing of card and cash sales
- A secure API gateway (Node.js/Express) protects the system
- Decentralised data control instead of closed third-party ecosystems
Sub-millisecond data synchronisation
The whole sales floor and product catalogue are bound together in one fast, real-time ecosystem running on a NoSQL cloud database.
When an organiser changes a price in the master admin, the change is pushed asynchronously to every till in under a millisecond, with no manual reload. Sales logistics update continuously at the same time, giving management a complete live picture of takings and receipts straight from their phone.
- A global real-time state manager in the cloud
- Asynchronous millisecond synchronisation of product catalogues
- Live overview of order data and sales logistics
Bring your own device and immediate ROI
The architecture supports bring your own device, so staff can take payments straight from their own iPads and iPhones. That removes the cost of renting expensive traditional till terminals entirely. Together with the end of manual bookkeeping, it adds up to a saving of more than DKK 12,000 per event. OSIS Payment Suite carries a formal commercial market value of DKK 1,000,000 as a scalable enterprise SaaS product.
