Frequently Asked Questions
- How is a fintech wallet app secured?
- AppMatic Tech applies biometric authentication, device encryption, and session controls in the Flutter app, with sensitive operations verified against a secure Node.js backend rather than trusted on the device alone.
- Does the app handle KYC onboarding?
- Yes. AppMatic Tech builds a KYC onboarding flow with document capture and verification, so a new user is identity-checked before transacting.
- Why Flutter for a wallet app?
- AppMatic Tech uses Flutter to ship one codebase to iOS and Android with a consistent, tested payment UI, which shortens delivery while native modules handle biometrics on each platform.
