Prerequisite

You will need a valid license to use the Digius SDK, which can be obtained by contacting support@frslabs.com .

Depending on the license - offline or online - you have opted for, the ping functionality to billing servers will be disabled or enabled. For instance, if you have opted for the offline SDK model, then there will be no server ping needed to our billing server to bill you. However, if you have chosen a transaction based pricing, then after each transaction, a ping request will be made to our billing server. This cannot be overrided by the App. A point to note is that if the ping transaction fails for any reason, the whole transaction will be void without any results from the SDK.

Once you have the license , follow the below instructions for a successful integration of Digius SDK onto your iOS Application.

Getting Started

Swift

1. Initialize the input parameters and import delegate DigiusControllerDelegate

class YourViewController: UIViewController,DigiusControllerDelegate {

    func digiusControllerSuccess(_ scanner: Digius.DigiusController, didFinishScanningWithResults results: Digius.digiusResult) {
        var getAadharData = [String:Any]()
        getAadharData = (results.AadhaarResult) // Return the Aadhaar result
        print(results.digiusDocumentType) // Return type of document
    }
    
    func digiusControllerFailed(_ scanner: Digius.DigiusController, didFailWithError error: Int) {
        print(error)
    }
}

2. Invoke Digius SDK

    // ...
    
    override func viewDidLoad(_ animated: Bool) {
        let digius = DigiusController(showInstruction: true, delegate:self)
        digius.modalPresentationStyle = .fullScreen
        digius.licenceKey = "DIGIUS_LICENCE_KEY"
        present(digius, animated: false, completion: nil)
    }
    
    // ...

String	getAadharData["photo"]	Returns user's photo in BASE64 String
String	getAadharData["lastFourDigits"]	Returns last four digits of aadhaar
String	getAadharData["issuedDate"]	Returns aadhaar issued date and time

PHOTO: Convert BASE64 into Image

  func convertBase64StringToImage (imageBase64String:String) -> UIImage {
      let imageData = Data(base64Encoded: imageBase64String)
      let image = UIImage(data: imageData!)
      return image!
  }
  
  convertBase64StringToImage(imageBase64String: (getAadharData["photo"]) as! String)
