The Problem Issuers Run Into
Card issuers and processors are expected to deliver “bank-grade” digital experiences, but building a cardholder app internally often means:
-
long delivery cycles and constant backlog pressure
-
fragmented integrations (KYC, notifications, loyalty, fraud tools, support chat, etc.)
-
recurring maintenance across iOS/Android releases, security updates, and compliance changes
-
inconsistent experiences across different clients and programs
Our Solution
A cardholder app and middleware, delivered as a full lifecycle service
We provide a production-ready white-label app and the integration layer that connects it to your existing issuing and processing stack so you can roll it out across all your programs with a repeatable delivery model.

What We Provide
White-label cardholder app
A modern, configurable app that you brand and deploy for each program, covering the core journeys cardholders expect:
-
onboarding and secure access
-
card and account overview
-
transaction history and statements
-
notifications and in-app communication
-
self-service controls and settings
Integration layer
A middleware layer that:
-
standardizes API contracts for your clients/programs
-
connects to your processor/core/IAM and other systems
-
makes it easier for your clients to add third-party services without redesigning the app each time
-
supports versioning and controlled change as you expand features
Compliance-ready patterns & security controls
The solution is built with issuer-grade expectations in mind:
-
strong authentication flows (configurable to your IAM/SCA approach)
-
role-based access and auditability for operational actions
-
secure session handling and traffic controls
-
logging/monitoring hooks aligned to enterprise operations
Program rollout capability
We don’t deliver “one app once.” We set you up to deploy to multiple programs with:
-
repeatable rollout playbooks
-
program-specific configuration and branding
-
integration templates and release governance
-
a scalable process for onboarding new clients quickly
