Work Flow:

  • HomeActivity - When the application starts, the user will see this Activity. This Activity actually contains a small part of the user interface of the “Bajaj Finserv” application, where we added a CardView of “KYC Verification”.
  • KYCVerificationActivity - As the user clicks on the VERIFY button it takes the user this activity. In this Activity user required to fill the basic details need for KYC purpose, we have a small forms for the same as the company need more user data we add more fields their, for the development purpose we are only using some basic details only, we can also include a OTP verification field in this activity which will be send to the mobile number which linked to the Aadhaar Number. After filling the basic details, the user will have to choose whether he/she would Capture the document image or choose from Gallery.
  • Camera Button - The user clicks on the camera button, it will open the camera’s intent then the user has to click the document image as a normal snapshot. As soon as the picture is clicked the user will be redirected to a ImageCropperActivity.
  • Gallery Button - The user clicks on the camera button, it will open the gallery’s intent user will select the required document. As soon as the picture is clicked the user will be redirected to a ImageCropperActivity.
  • ImageCropperActivity - In this Activity, users will have to use the various document editing options or proceed with the default magic color which is done by Machine Learning which resides in the openCVLibrary. After trimming the document the user will be redirected to the KYCVerification activity, where they can see a small thumbnail of their document. After doing all the process, there is a DONE Button in the bottom of the screen.
  • Done Button - As soon as user clicks on the Done Button, for sake of completeness we check that users has really filled the details, if all thing goes right the details of the user is sended to the Firebase Cloud Storage (or in production Bajaj Finserv Backend) along with the document image. Which can be used by the administration for further verification. This is the whole working of our “Aviza - Bajaj Finserv”.
  • SplashScreen - Just for sake of better user interface we have implemented a splash screen which is shown during the start-up of the application.
