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.

Configuration options provided in the Uqudo Enrollment builder are:

Property	Type	Optional	Default	Description
authorizationToken	String	No	null	See Authorisation
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
enableFacialRecognition	Boolean	Yes	false	Enable facial recognition. See Facial Recognition Configuration for additional configurations
enableBackgroundCheck(isDisableConsent, backgroundCheckType, monitoring, skipView)	Boolean, Integer, Boolean, Boolean	Yes	None	Enable background check. See Background Check Configuration for details
add(documentConfig)	UQDocumentConfig	No	None	Add document config object. See Document Configuration for details.
returnDataForIncompleteSession	Boolean	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 Session Status Handling). Please note that you can expect some data only if the user passes at least the scanning step
setAppearanceMode	AppearanceMode	No	SYSTEM	Set the appearance mode for the SDK. The following options are available: SYSTEM: the SDK checks the OS setting for light or dark mode LIGHT: force the light mode DARK: force the dark mode
enableLookup()	None	Yes	None	Enable third party lookup (Government database). See the supported documents and the data returned in Lookup Object Note: this feature requires an additional permission and must be explicitly requested
enableLookup(documentTypes)	Array of document types	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 in in Lookup Object Note: this feature requires an additional permission and must be explicitly requested
allowNonPhysicalDocuments	Boolean	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	Boolean	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

Document Configuration

Objective-C

UQDocumentConfig *passport = [[UQDocumentConfig alloc] initWithDocumentType:PASSPORT];
passport.disableExpiryValidation = NO;
passport.enableAgeVerification = -1;
passport.scan = <Scan Config Object>;
passport.reading = <Reading Config Object>;

Swift

let passport = UQDocumentConfig(documentType: PASSPORT.rawValue)
passport.disableExpiryValidation = false
passport.enableAgeVerification = -1
passport.scan = <Scan Config Object>
passport.reading = <Reading Config Object>

See the options described below:

Property	Type	Optional	Default	Description
disableExpiryValidation	Boolean	Yes	false	Allows to scan expired documents
enableAgeVerification	Int	Yes	-1 (disabled)	Enable age verification. If the age calculated from the document is not above or equals the defined age, the scan fails showing a message to the user accordingly. Age must be above 0 otherwise is not taken into consideration
scan	UQScanConfig	Yes	None	Add scan configuration. See Scan Configuration for details
reading	UQReadingConfig	Yes	None	Add reading configuration. See Read Configuration for details

Scan Configuration

Objective-C

UQScanConfig *scanConfig = [[UQScanConfig alloc] init];
scanConfig.disableHelpPage = NO;
scanConfig.faceMinimumMatchLevel = 2;
[scanConfig enableScanReview:NO backSide:NO];
scanConfig.enableUpload = NO;

Swift

let scanConfig = UQScanConfig()
scanConfig.disableHelpPage = false
scanConfig.faceMinimumMatchLevel = 2
scanConfig.enableScanReview(false, false)
scanConfig.enableUpload = false

See the options described below:

Property	Type	Optional	Default	Description
disableHelpPage	Boolean	Yes	False	Disable scanning help page
faceMinimumMatchLevel	Integer	Yes	None	Defines the minimum match level that the facial recognition has to meet for scanned picture of this specific document
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	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

let readingConfig = UQReadingConfig()
readingConfig.enableReading = true
readingConfig.faceMinimumMatchLevel = 3
readingConfig.forceReading(false)
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	3	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	No	false	Disable consent option for the user
backgroundCheckType	Integer	No	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:

1. 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

2. 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_CANCELLED = User canceled the enrollment process

• SESSION_EXPIRED = Session expired or not found

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

• SESSION_INVALIDATED_READING_INVALID_DOCUMENT = Session gets invalidated because the digital signature validation fails after reading the data in the chip

• SESSION_INVALIDATED_CHIP_VALIDATION_FAILED = Session gets invalidated because chip authentication fails (e.g. chip authentication for passports)

• 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 the end user denied camera permission

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.
