PLATFORM ARCHITECTURE

Secure, API-first kiosk middleware

A policy-driven coordination layer between business applications, peripherals, central operations and digital identity services.

KioWare architecture flow
TECHNICAL DECISION RECORD

Architecture designed for hardware change and operational control

01Application boundary

Applications call capabilities, not drivers

Reduce coupling and allow hardware models to change without rewriting business journeys.

02Security boundary

Identity-aware local service

Every request is bound to application identity, session, scope and device state.

03Operations boundary

Desired state separated from immediate commands

Configuration, release, command and rollback carry history, TTL and verified outcomes.

04Evidence boundary

End-to-end Trace ID

Connect applications, Agent, adapters, devices and backends in one audit chain.

API FIRST

Applications no longer integrate each driver

  • Capability-based APIs independent of hardware model
  • Local-only endpoints by default
  • JWT, mTLS and signed assertions for app, user and device identities
  • Offline queues, retry policies and event buffering
  • End-to-end trace IDs across application, middleware, device and backend
Peripheral and connection map
CORE CAPABILITIES

Runtime at the edge, governance at the center

Session management

Checkpoints, timeout, incident recovery, single-writer lock and duplicate prevention.

Policy Engine

Decides which application may use which device in which tenant and context.

Secure Storage

Encrypts temporary data, purges it at session end and never stores PIN/OTP/biometrics.

Event & Offline

Normalizes events, queues locally, retries by policy and synchronizes audit evidence.

Trust Layer

OIDC/OAuth2, consent, step-up authentication, signed evidence and remote signing.

Observability

Telemetry, audit trails, SLA, tracing and controlled support bundles.

DEPLOYMENT

Four deployment models

On-premise

For banks, government, healthcare and data sovereignty requirements.

Hybrid

Cloud/private-cloud Control Plane with sensitive services in private zones.

Managed Service

Mobile-ID assisted operations, monitoring and SLA for distributed fleets.

Multi-tenant SaaS

For partners, SIs, franchises and multi-brand ecosystems.

DEVELOPER FLOW

Five-step execution flow

01

Register application

Issue app identity and device access scope.

02

Start session

Obtain a local token and discover kiosk capabilities.

03

Call normalized APIs

Print, scan, capture, NFC and pay through one API surface.

04

Enforce & route

Middleware checks identity, authorization, session and policy.

05

Audit & trust

Events reach the Control Plane; Trust Layer is invoked when required.
