1. What is the Document Detector SDK and what is its main functionality?

Answer:

The Document Detector SDK is designed to capture identity documents, such as RG, CNH, and RNE, with high-quality imaging and reliable data extraction. Instead of relying on a standard camera, it utilizes a smart camera with features like automatic capture and document detection, reducing the chance of low-quality or unusable photos. This functionality enhances onboarding processes, ensuring that documents are captured accurately and efficiently for identity verification and other secure applications.

5. Is the Document Detector SDK compatible with Expo?

Answer:

Yes, the Document Detector SDK can be used with Expo, but only in the Bare Workflow, which allows for the necessary native configurations. To set up the SDK for Expo, follow these steps:

• Android setup:

  1. Add the following Maven repositories to android/build.gradle:

     allprojects { 
         repositories { 
             ... 
             maven { url 'https://repo.combateafraude.com/android/release' }
             maven { url 'https://jitpack.io' }
         } 
     }     

  2. Ensure Java 8 compatibility by configuring android/app/build.gradle.

     android {
         ...
         compileOptions {
             sourceCompatibility JavaVersion.VERSION_1_8
             targetCompatibility JavaVersion.VERSION_1_8
         }
     }

• iOS setup:

  1. Add the following sources to your Podfile to access required dependencies.

     source 'https://github.com/combateafraude/iOS.git'
     source 'https://cdn.cocoapods.org'

These configurations enable the SDK to function effectively in an Expo environment with native support.

For detailed instructions, see the Installation section.
