Mobile SDK

From ID Capture to Liveness, Every Module On-Device

The iOS and Android SDKs are modular; add only the steps you need to your flow.

ID Capture

Catcher

AI recognises only the relevant ID document in the camera and captures the sharpest frame without the user pressing any button.

  • AI-controlled capture of the relevant ID only
  • Auto-focus and auto-capture
  • Landscape and portrait experience options
  • Event-based user guidance
  • Voice guidance
  • Animated guidance
  • Event-based UX
  • Robust app logging
  • Avatar and chatbot guidance
Web SDK

One Tag, Every Browser, Zero Setup Hassle

The <techsign-kyc> Web Component adds card reading and face verification to any web project in a few lines.

Framework-agnosticPlain HTML, React, Vue, Angular, PHP or .NET — the same component works everywhere.
In-browser AICard detection and face analysis run on-device with TensorFlow and MediaPipe.
Smart loadingIf the face step is off, the face module is never downloaded; you can also serve the models from your own server.
Three verification modesCloud, standalone, or host mode that only captures and forwards to your own API.
Desktop to mobileDesktop users continue the flow on their phone via QR code.
Languages, themes, accessibilityOffers Turkish and English, text customisation, light and dark themes, and keyboard and screen reader support.

Integration

Go Live in Three Steps

  1. 01

    Create a token

    Your server obtains a short-lived transaction token from the Prove ID API. Credentials never reach the browser.

    POST /identification/start
  2. 02

    Add the SDK

    Add the mobile SDK or the Web Component and pass the token; flow, theme and language come ready.

    <techsign-kyc token="…">
  3. 03

    Receive the result

    Get the result via the complete event or a webhook; every record lands in the Management Panel.

    on('complete', verify)

Infrastructure

Enterprise Scale, On Your Infrastructure

Server-side verification

Every on-device check is re-verified on the server; client-side manipulation is not possible.

Microservice architecture

Scales horizontally on OpenShift, Kubernetes or your custom environments.

On-premise or cloud

Your data stays in your own data centre or in ready-made private and public cloud options.

Blacklist checks

Stop repeat fraud with face, national ID and device-based blacklists.

Robust logging

Audit-ready, end-to-end transaction logs are kept across app and backend.

Panel and reporting

In the role-based panel, transactions are flagged, verification media is reviewed and thresholds are managed.
