Enrolment Flow

In order to use our SDK you need an authorization token. Please check our API "Authorisation" in this regard.

The following method should be called when the application is initiated:

UqudoSDK.init(applicationContext)

The Uqudo SDK provides a builder class to initiate the "Enrollment Flow". See the example below:

try {
   val authorizationToken = ... // access_token from the API response
   val uqudoIntent = UqudoBuilder.Enrollment()
            .setToken(authorizationToken)
            .add(
                DocumentBuilder(applicationContext)
                    .setDocumentType(DocumentType.PASSPORT)
                    .enableReading(ReadingConfigurationBuilder()
                        .forceReadingIfSupported(true)
                        .build()
                    )
                    .build()
            )
            .enableFacialRecognition()
            .build(this)
        startActivityForResult(uqudoIntent, 101)
} catch( e: Exception ){
    ...
}

Uqudo Enrollment Builder Configuration

In order to check if the document type supports the "Enrollment Flow" you can use the following method:

DocumentType.NGA_DL.enrollmentSupported

Configuration options provided in the Uqudo Enrolment builder are:

Property	Type	Optional	Default	Description
setToken(token)	String	No	null	See Authorisation
setNonce(nonce)	String (max size 64 chars)	Yes	null	Nonce provided by the customer mobile application when the SDK is initiated. It is useful to make sure the process has been initiated by the customer mobile application. It should be generated server side.
setSessionId(sessionId)	String (UUID v4)	Yes	Auto generated	Required during the enrolment process using a QR code, see QR code App. Note: make sure to create always a new session id when you trigger the SDK flow
disableSecureWindow()	None	Yes	false	Whether to allow users to take screenshots and capture screen recording or not.
enableFacialRecognition()	None	Yes	none	Enable facial recognition with the default configuration, see Facial Recognition Configuration.
enableFacialRecognition(configuration)	FacialRecognitionSpecification	Yes	none	Enable facial recognition with a custom configuration, see Facial Recognition Configuration.
enableBackgroundCheck(configuration)	BackgroundCheckSpecification	Yes	none	Enable background check with a custom configuration, see Background Check Configuration.
add(document)	Document	No	none	Add a document to the enrolment process, see Scan Configuration.
returnDataForIncompleteSession()	None	Yes	false	When enabled, if the user or the SDK drops the session before completion, the SDK will return the partial data together with the SessionStatus object (see Handling the Result). Please note that you can expect some data only if the user passes at least the scanning step
enableLookup()	None	Yes	None	Enable third party lookup (Government database). See the supported documents and the data returned here Lookup object Note: this feature requires an additional permission and must be explicitly requested
enableLookup(documentTypes)	Variable length argument or Array	Yes	None	Enable third party lookup (Government database) filtered by document type. For instance, if your KYC process includes more than one document, you can decide to perform the lookup only for one single document. See the supported documents and the data returned here Lookup object Note: this feature requires an additional permission and must be explicitly requested
allowNonPhysicalDocuments()	None	Yes	false	If enabled allows scanning of non-physical documents (where the SDK doesn't reject scans upon detecting a screen) Note: Available only on SDK version 3.x and above
disableTamperingRejection()	None	Yes	false	If enabled directs the SDK not to dismiss the scan upon detecting tampering, specifically for ID photo tampering detection. Note: Available only on SDK version 3.x and above

Scan Configuration

The scanning has some customisation options which can be set using the DocumentBuilder object like below:

DocumentBuilder(applicationContext)
                    .setDocumentType(documentType)
                    .disableHelpPage()
                    .enableReading()
                    .build()

Below you can find the configuration options available:

Property	Type	Optional	Default	Description
setDocumentType(documentType)	DocumentType	No	None	Document type to scan. Please refer to the Scan API for supported Document Types.
disableHelpPage()	None	Yes	false	Disable scanning help page
enableReading()	None	Yes	None	Enable reading for the document, e.g. NFC reading of the chip with default configuration, see Read Configuration.
enableReading(configuration)	ReadingSpecification	Yes	None	Enable reading for the document, e.g. NFC reading of the chip, passing a reading specification object (see below), see Read Configuration.
setFaceScanMinimumMatchLevel(matchLevel)	Int	Yes	None	Defines the minimum match level that the facial recognition has to meet for scanned pictures related to this document. This configuration takes precedence from the global setting in the facial recognition configuration
setFaceReadMinimumMatchLevel(matchLevel)	Int	Yes	None	Defines the minimum match level that the facial recognition has to meet for pictures from the chip (e.g. NFC) related to this document. This configuration takes precedence from the global setting in the facial recognition configuration
disableExpiryValidation()	None	Yes	false	Allows to scan expired documents
enableScanReview(frontSide, backSide)	Boolean, Boolean	Yes	Not enabled	Enable scan review of the document for the front side, back side or both. After scanning the detected document side is presented to the user for review and confirmation
enableUpload()	None	Yes	false	Enable manual upload of the document instead of automatic scanning. The user can choose a single PDF that contains the image of the document. For a two-side document the first picture must be the front side and the second picture the back side. If enabled, the reading step is automatically disabled
enableAgeVerification(minAge)	Int	Yes	-1 (disabled)	Enable age verification. If the age calculated from the document is not above or equals minAge, the scan fails showing a message to the user accordingly. Min age must be above 0 otherwise is not taken into consideration

Read Configuration

In order to check if the document type supports the reading step (NFC) you can use the following method:

DocumentType.NGA_DL.readingSupported

In order to configure specific options for the reading part, see the example below:

....
                DocumentBuilder(applicationContext)
                    .setDocumentType(documentType)
                    .enableReading(
                       ReadingConfigurationBuilder()
                           .forceReading(false)
                           .forceReadingIfSupported(false)                                                     
                           .build()
                 )
                .build()

Reading configuration options available:

Property	Type	Optional	Default	Description
forceReading(value)	Boolean	Yes	false	Force the reading part. Users will not be able to skip the reading part. If the device does not support NFC and forceReading is set to true, the uqudo builder will throw and exception that needs to managed by the application
forceReadingIfSupported(value)	Boolean	Yes	false	Force the reading part only if NFC is supported. Users will not be able to skip the reading part if NFC is supported. Otherwise, the reading part is skipped and the user taken to the next step. Note: This option has been deprecated in version 3.0.0 and is the default behaviour now
forceReadingTimeout(timeout)	Integer	Yes	-1 (disabled)	Defines the timeout in seconds. If the user isn't able to perform the NFC scanning of the document before the timeout expires, a message is shown accordingly and the user is allowed to skip the NFC step.

You can also control the app for devices with NFC or not by turning the feature required as true or false in AndroidManifest.xml. By doing so, the app will only be available to devices with NFC if set true

<uses-feature
   android:name="android.hardware.nfc"
   android:required="true"
   tools:node="replace" />

Facial Recognition Configuration

In order to check if the document type supports facial recognition you can use the following method:

DocumentType.NGA_DL.facialRecognitionSupported

Note: By default the facial recognition is disabled. You need to enable Facial Recognition explicitly. See the example below:

...
        .enableFacialRecognition(
           FacialRecognitionConfigurationBuilder()
              .setFaceReadMinimumMatchLevel(3)
              .setFaceScanMinimumMatchLevel(2)
              .build()
        )

The above example shows how you can disable the help page on the facial recognition part.

Facial Recognition configuration options available:

Property	Type	Optional	Default	Description
setScanMinimumMatchLevel(matchLevel)	Int	Yes	None	Defines the minimum match level that the facial recognition has to meet for scanned pictures
setReadMinimumMatchLevel(matchLevel)	Int	Yes	None	Defines the minimum match level that the facial recognition has to meet for pictures from the chip (e.g. NFC)
enableAuditTrailImageObfuscation(obfuscationType)	ObfuscationType	Yes	None	Enables audit trail image background obfuscation leaving only the face visible. It can be used when there are privacy concerns related to the background of the selfie taken by the user and shared in the SDK result. There are two types of obfuscations: FILLED: the background is entirely replaced FILLED_WHITE: the background is entirely replaced with a wihte background BLURRED: the background is heavily blurred, making sure the objects in the background are not clearly recognizable, but still giving a perception of the environment surrounding the user and therefore still being able to validate the reality of the image. If privacy is a concern, we recommend using this option
setMaxAttempts(maxAttempts)	Int	Yes	3	Set the max failed facial recognition attempts before dropping the session. Note: only values between 1 and 3 are taken into consideration.
allowClosedEyes()	None	Yes	False	Allows to have closed eyes during facial recognition.
enableOneToNVerification()	None	Yes	False	Once activated, following a successful facial recognition (confirming liveness and matching the face), the system initiates a search for the user's selfie within your tenant. If the selfie is not found, it is added, and the indexed facial features are stored in the database. The SDK result includes a unique ID in the face object, along with an indication of whether there was a match with a previously onboarded selfie. It's essential to store this unique ID in your system alongside the user's record, facilitating future searches for users with the same ID. Please be aware that this option requires a specific permission, otherwise, it will be disregarded

Background Check Configuration

Note: This feature requires an additional permission and must be explicitly requested

Note: By default the Background Check is disabled. You need to enable Background Check explicitly. See the example below:

...
        .enableBackgroundCheck(
             BackgroundCheckConfigurationBuilder()
               .skipView()
               .build()
         )

Background Check configuration options available:

Property	Type	Optional	Default	Description
disableConsent()	None	Yes	false	Disable consent option for the user
setBackgroundCheckType(type)	BackgroundCheckType	Yes	RDC	Sets the background check type RDC
enableMonitoring()	None	Yes	false	Enable continuous monitoring. See API documentation for details.
skipView()	None	Yes	false	If enabled, the step will be skipped, and the SDK will trigger the background check without any user interaction.

Handling Exceptions

The Uqudo SDK will throw certain exceptions which need to be handled by the application. The Exceptions are:

1. IllegalStateException - e.g. enabling reading for a document that doesn’t support reading or required configuration missing

2. UnsupportedDeviceException - e.g. on DocumentBuilder().build() if force reading is enabled and the device doesn’t support NFC

3. InitializationException - thrown when the SDK fails to load native libraries due to a bug on certain Android devices. This exception enables your application to handle the issue gracefully instead of crashing.

Handling the Result

The enrollment result will be available to the application in the calling Activity’s onActivityResult method:

...
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
   super.onActivityResult(requestCode, resultCode, data)
   if (resultCode == Activity.RESULT_OK) {
       val result = data?.getStringExtra("data")
   } else if (resultCode == Activity.RESULT_CANCELED) {
       if (data != null) {
         val sessionStatus = data.getParcelableExtra("key_session_status") as SessionStatus
         println("Enrollment failed due to ${sessionStatus.sessionStatusCode.message} at ${sessionStatus.sessionTask.name()}")
       }
   }
}

If the resultCode is equals to Activity.RESULT_OK you can find the SDK result in the data attribute. The string is the JWS, see "SDK result" for details.

If the resultCode is equals to Activity.RESULT_CANCELED you can find the SessionStatus object result in the data attribute under the key “key_session_status”. The SessionStatus contains the following properties:

sessionStatusCode as SessionStatusCode enum that contains the following error codes:

1. USER_CANCELLED = User canceled the enrollment process

2. SESSION_EXPIRED = Session expired or not found

3. UNEXPECTED_ERROR = Something went wrong. In the message the details of the error

4. SESSION_INVALIDATED_CHIP_VALIDATION_FAILED = Session gets invalidated because the CHIP validation of the card fails and the reading step is forced by configuration

5. SESSION_INVALIDATED_READING_NOT_SUPPORTED = Session gets invalidated because the document doesn’t support reading (e.g. no chip available) and the reading step is forced by configuration

6. SESSION_INVALIDATED_FACE_RECOGNITION_TOO_MANY_ATTEMPTS = Session gets invalidated because of too many failed facial recognition attempts

7. SESSION_INVALIDATED_CAMERA_NOT_AVAILABLE = Session gets invalidated because the camera is not available

8. SESSION_INVALIDATED_CAMERA_PERMISSION_NOT_GRANTED = Session gets invalidated because camera the end user denies camera access

sessionTask as SessionTask enum that contains the following codes:

1. SCAN = The scanning task

2. READING = The NFC reading task

3. FACE = The facial recognition task

4. BACKGROUND_CHECK = The background check task (only if skipView() is not enabled)

data as String that contains the JWS object with the partial data of an incomplete KYC session. Returning the partial data for an incomplete KYC session is disabled by default, please see Enrollment Builder Configuration for details.
