Android KYC SDK - OCR & Face Match
Accura OCR is used for Optical character recognition.
Accura Face Match is used for Matching 2 Faces. Source and Target. It matches the User Image from a Selfie vs User Image in document.
Accura Authentication is used for your customer verification and authentication.Unlock the True Identity of Your Users with 3D Selfie Technology
Below steps to setup Accura SDK's to your project.
Add it in your root build.gradle at the end of repositories.

Set Accura SDK as a dependency to our app/build.gradle file.

Create "assets" folder under app/src/main and Add license file in to assets folder.

Generate your Accura license from https://accurascan.com/developer/dashboard
