VCheck for Flutter

VCheck is online remote verification service for fast and secure customer access to your services.

This package represents VCheck SDK for Flutter(iOS, Android). The native plugins in the package itself use dependencies of Android and iOS SDKs channeled to Flutter SDK.

Features

Document validity: Country and document type identification. Checks for forgery and interference (glare, covers, third-party objects)
Document data recognition: The data of the loaded document is automatically parsed
Liveliness check: Determining that a real person is being verified
Face matching: Validate that the document owner is the user being verified
Easy integration to your service's Flutter app out-of-the-box
