Patented Payment Security Platform

The client
Securter Systems Inc.
A fintech startup developing next-generation payment security technology to combat the billions of dollars lost annually to online credit card fraud.
Project Overview
Project Overview
Superscript Systems served as Securter's dedicated development partner, building a complete payment security platform from concept through patent filing. The project required creating proprietary risk management algorithms, mobile applications for iOS and Android, backend infrastructure, and multiple web interfaces,all working together to transform smartphones into secure payment terminals by reading EMV-enabled credit cards.
Challenges
Building a novel payment security system presented significant technical and business challenges:
Complex Technical Requirements The solution needed to integrate smartphone hardware capabilities (NFC reading), proprietary risk management algorithms, real-time payment processing, and secure data transmission, all while maintaining PCI compliance standards.
Multi-Platform Development The system required coordination across web applications, backend services, iOS native apps, and Android native apps, all working seamlessly together.
Patentable Innovation The technology had to be genuinely novel enough to warrant patent protection, requiring deep domain expertise in both payment security and mobile technology.
Production-Grade Security Given the sensitive nature of payment data, the platform needed enterprise-level security architecture from day one, even though the client was an early-stage company.
Solution
Superscript provided a dedicated senior team that took full ownership of the technical development:
Comprehensive Platform Development
- Backend payment processing infrastructure built on .NET Core and AWS
- Proprietary risk management algorithms for fraud detection
- Native iOS app (Swift) and Android app (Kotlin/Java) enabling EMV card reading
- Multiple web interfaces for merchants and administrators
- PostgreSQL database architecture for secure transaction management
Patent Strategy Development Michael Shmulevich, Superscript's CEO, worked directly with the founding team to develop the patent strategy. The technical innovation resulted in two patent applications, protecting the unique approach to mobile payment security.
Enterprise-Quality Architecture Despite being a startup project, we built the platform with mid-market and enterprise scalability in mind: proper source control, CI/CD pipelines, comprehensive testing, and security protocols that would support growth.
Results
Patent-Pending Technology: Two patent applications filed, protecting genuinely novel approaches to payment security using smartphone technology.
Complete Platform Delivered: Full-stack payment security solution including mobile apps, backend infrastructure, risk management algorithms, and web interfaces—demonstrating end-to-end product development capability.
Technical Validation: The CEO of Securter noted: "What makes them unique is their experience and ability to deliver an actual product." This speaks to our focus on production-ready code rather than prototypes.
Long-Term Partnership Model: While the product didn't reach commercial production due to market conditions, the technical work validated Superscript's ability to handle complex fintech projects requiring deep expertise in payments, security, and mobile development.
Proof of Capability: This project demonstrates what mid-market fintech companies can expect: a dedicated team that understands regulatory requirements, builds patent-level innovation, and delivers enterprise-quality architecture, not just code.
