Enrolment Flow

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

The Uqudo SDK provides a builder class to initiate the "Enrollment Flow". The example below assumes that you have already initialised the SDK:

Objective-C

UQBuilderController *builderController = [UQBuilderController defaultBuilder];
builderController.delegate = self;
builderController.appViewController = self;
//
UQEnrollmentBuilder *enrollmentBuilder = [[UQEnrollmentBuilder alloc] init];
enrollmentBuilder.authorizationToken = authorizationToken;
//
UQFacialRecognitionConfig *frConfig = [[UQFacialRecognitionConfig alloc] init];
frConfig.enableFacialRecognition = YES;
enrollmentBuilder.facialRecognitionConfig = frConfig;
//
UQDocumentConfig *documentConfig = [[UQDocumentConfig alloc] initWithDocumentType:PASSPORT];
//
UQReadingConfig *readingConfig = [[UQReadingConfig alloc] init];
readingConfig.enableReading = YES;
[readingConfig forceReadingIfSupported:YES];
documentConfig.reading = readingConfig;
//
[enrollmentBuilder add:documentConfig];
//
[builderController setEnrollment:enrollmentBuilder];
[builderController performEnrollment];

Swift

let uqudoBuilder = UQBuilderController.defaultBuilder()
uqudoBuilder.delegate = self
uqudoBuilder.appViewController = self
//
let enrollmentBuilder = UQEnrollmentBuilder()
enrollmentBuilder.authorizationToken = authorizationToken
//
let frConfig = UQFacialRecognitionConfig()
frConfig.enableFacialRecognition = true
enrollmentBuilder.facialRecognitionConfig = frConfig
//
let passport = UQDocumentConfig(documentType: PASSPORT.rawValue)
//
let readingConfig = UQReadingConfig()
readingConfig.enableReading = true
readingConfig.forceReadingIfSupported(true)
passport.reading = readingConfig
//
enrollmentBuilder.add(passport)
//
uqudoBuilder.setEnrollment(enrollmentBuilder)
uqudoBuilder.performEnrollment()

Uqudo Enrollment Builder Configuration

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

Objective-C

UQDocumentConfig *documentConfig = [[UQDocumentConfig alloc] initWithDocumentType:PASSPORT];
[documentConfig isEnrollmentSupported]

Swift

let documentConfig = UQDocumentConfig(documentType: PASSPORT)
document.isEnrollmentSupported()

Please refer to the Scan API for supported Document Types.

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

Boolean

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

Read Configuration

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

Objective-C

UQDocumentConfig *documentConfig = [[UQDocumentConfig alloc] initWithDocumentType:PASSPORT];
[documentConfig isSupportReading]

Swift

let documentConfig = UQDocumentConfig(documentType: PASSPORT)
document.isSupportReading()

Objective-C

UQReadingConfig *readingConfig = [[UQReadingConfig alloc] init];
readingConfig.enableReading = YES;
readingConfig.faceMinimumMatchLevel = 3;
[readingConfig forceReading:NO];
readConfig.forceReadingTimeout = -1;

Swift

readingConfig.forceReadingTimeout(-1)

See the options described below:

Property

Type

Optional

Default

Description

Property

Type

Optional

Default

Description

enableReading

Boolean

Yes

false

Enable reading for the document, e.g. NFC reading of the chip

faceMinimumMatchLevel

Integer

Yes

None

Defines the minimum match level that the facial recognition has to meet for the picture in the chip for this specific document

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 enrollment builder will throw and exception when you trigger SDK

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, after the Scan user will be moved to the next step. Note: This option has been deprecated in version 3.0.0 and is the default behaviour now

forceReadingTimeout

Int

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.

Facial Recognition Configuration

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

Objective-C

UQDocumentConfig *documentConfig = [[UQDocumentConfig alloc] initWithDocumentType:PASSPORT];
[documentConfig isSupportFaceRecognition]

Swift

let documentConfig = UQDocumentConfig(documentType: PASSPORT)
document.isSupportFaceRecognition()

Note: By default the facial recognition is disabled. You will have to enable facial recognition explicitly as per the below example:

Objective-C

UQFacialRecognitionConfig *config = [[UQFacialRecognitionConfig alloc] init];
config.enableFacialRecognition = YES;
config.scanMinimumMatchLevel = 2;
config.readMinimumMatchLevel = 3;
config.maxAttempts = 3;
config.allowClosedEyes = NO;

Swift

let config = UQFacialRecognitionConfig()
config.enableFacialRecognition = true
config.scanMinimumMatchLevel = 2
config.readMinimumMatchLevel = 3
config.maxAttempts = 3
config.allowClosedEyes = false

Facial Recognition configuration options available:

Property

Type

Optional

Default

Description

scanMinimumMatchLevel

Integer

Yes

None

Defines the minimum match level that the facial recognition has to meet for scanned pictures

readMinimumMatchLevel

Integer

Yes

None

Defines the minimum match level that the facial recognition has to meet for pictures from the chip (e.g. NFC)

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

maxAttempts

Int

Yes

Set the max failed facial recognition attempts before dropping the session. Note: only values between 1 and 3 are taken into consideration.

allowClosedEyes

bool

Yes

false

Allows to have closed eyes during facial recognition.

enableOneToNVerification

bool

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:

Objective-C

[enrollmentBuilder enableBackgroundCheck:YES type:RDC monitoring:NO skipView:YES];

Swift

enrollmentBuilder.enableBackgroundCheck(true, type: RDC, monitoring: false, skipView: true)

Background Check configuration options available:

Property

Type

Optional

Default

Description

isDisableConsent

Boolean

false

Disable consent option for the user

backgroundCheckType

Integer

RDC

Sets the background check type

RDC

DOW_JONES

enableMonitoring

Boolean

Yes

false

Enable continuous monitoring. See API documentation for details

skipView

Boolean

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:

IllegalStateException - e.g. enabling the "Lookup Flow" for a document that doesn’t support it or because facial recognition is enabled and the documcent doesn't support it or because of some required configuration missing
UnsupportedDeviceException - e.g. the device is rooted

Handling the Result

The enrollment result will be available to the builder delegate (the class that initiates the SDK has to extends UQBuilderControllerDelegate) if the operation succeeds and you get the result with the following method. See "SDK result" for the details about the JWS string:

Objective-C

- (void)didEnrollmentCompleteWithInfo:(NSString *)info {}

Swift

func didEnrollmentComplete(withInfo info: String) {}

A failure scenario can be handled with the following method:

Objective-C

- (void)didEnrollmentIncompleteWithStatus:(UQSessionStatus *)status {}

Swift

func didEnrollmentIncomplete(with status: UQSessionStatus) {}

See the details about the UQSessionStatus below.

Session Status Handling

The UQSessionStatus is used to identify the status of the enrollment task. The object contains the following properties:

@property (nonatomic, assign) NSInteger statusCode;
@property (nonatomic, assign) NSInteger statusTask;
@property (nonatomic, strong) NSString *message;
@property (nonatomic, strong) NSString *data;

statusCode contains the following error codes:

USER_CANCEL = User cancel the operation
SESSION_EXPIRED = Session expired or not found
UNEXPECTED_ERROR = Something went wrong. In the message the details of the error
SESSION_INVALIDATED_CHIP_VALIDATION_FAILED = Session gets invalidated because the CHIP validation of the card fails, and the reading step is forced by configuration
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
SESSION_INVALIDATED_FACE_RECOGNITION_TOO_MANY_ATTEMPTS = Session gets invalidated because of too many failed facial recognition attempts
SESSION_INVALIDATED_CAMERA_NOT_AVAILABLE = Session gets invalidated because the camera is not available
SESSION_INVALIDATED_CAMERA_PERMISSION_NOT_GRANTED = Session gets invalidated because camera the end user denies camera access

statusTask contains the following codes:

SCAN = The scanning task
READING = The NFC reading task
FACE = The facial recognition task
BACKGROUND_CHECK = The background check task (only if skipView() is not enabled)

message contains the details of the status code

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.
