Introduction

IMPORTANT NOTE

Major versions represent a big change from the previous major version, providing more capabilities and potential. At the same time, moving from a major version means a break in backward compatibility that must be managed using the provided migration guide. Please make sure to perform proper tests in development environments to ensure that everything is working as expected.

Differential features and improvements of WC SDKs

Document SDK is a JS library that allows detecting and capturing documents, using advanced detection techniques. This allows to carry out a document verification step in the context of the identity verification process offered by Veridas. Document SDK supports the identification of different types of documents such as ID Card, Driving License, Residence Permit, or Passport.

Document type

The SDK allows you to capture a large number of documents from all over the world. To see the complete list you can go to the following link: Documents. Depending on the type of document to be detected, Document SDK will ask the user to capture only the front part of the document (observe) or both sides (observe and reverse).

Camera

Document SDK, also refering in this documentation as VDDocument, takes into account the type of device being used and attempts to launch the camera (front facing or rear) that will provide the user with the best experience:

  • Rear camera is used on mobile devices (smartphones, tablets…)
  • Front camera is used on computers (desktops, laptops…)

To improve user experience, VDDocument attempts to capture images of the document automatically, by having the user center each side in a frame. VDDocument uses several algorithms to detect a document in the camera’s field of vision, and snaps the photo without need for further user action. Also, the user can take a photo manually by touching/clicking on the button when the manual capture option is enabled.

The camera attempts to start at Full HD (1080p), but lower resolutions are intended whether the devices are unable to support the optimal one.

The photo is taken in .JPG format, being a 1080p capture about 500KB on size.

Specifications

The following permission is required for the framework to work:

  • Camera: By default, the SDK launch Back camera on all devices (smartphones, tablets, desktops, laptops...), but you can choose the camera you want to use with the selectCamera property. With this property you can use the Front camera, interesting to capture documents.
