Mobile SDK

Accessibility improvements: We continuously improve the accessibility of our Android and cross-platform plugin SDKs to comply with EAA requirements, aligning with WCAG 2.1 Level A and AA criteria.

These recent updates enhance usability for users with vision impairments and include:

• We updated all links to include underlines, ensuring color isn’t the only way information or actions are conveyed.
• We added underlines to link buttons to ensure they’re easily identifiable, even without color cues.
• We raised the background opacity from 50% to 90% to improve visual clarity and focus during document capture.
• We updated our default styles to increase text and UI contrast, making content easier to read and more accessible.
• We updated the default Orca color scheme to increase contrast and improve visibility.

Improved TIN extraction: We streamlined TIN extraction from Italian ID documents, improving accuracy and efficiency while reducing manual input.

Web SDK

Improved document upload: We’ve enhanced the document upload experience in our Documents flows by reducing upload times.

This improvement shortens user journeys and decreases waiting times, resulting in a smoother overall onboarding experience.

Now live on Web. Mobile support coming soon — stay tuned!

Document NFC

Enhanced NFC flow: We’ve optimized the Document NFC flow for Spanish identity documents by leveraging data directly from the NFC chip when a scan is performed. As a result:

• The place of birth step is automatically skipped
• Tilted document images are automatically removed
• The overall flow is shorter and more efficient

These enhancements improve completion rates for Spanish flows.

Bank Account Verification

Migration to Tink: We’re transitioning from Klarna to Tink as our PSP to deliver improved performance, broader coverage, and a smoother payment experience.

The migration is fully handled by Fourthline — no action is required on your end.

The Fourthline Docs have been updated to reflect this change.

Mobile SDK

CameraX integration on Android (Beta): We are migrating our Android experience to the new CameraX library.

Expected benefits include:

• Higher-quality image and video capture
• Improved performance and smoother flows across our Documents and Biometrics solutions

App Drop-in & Web SDK

Improved

Fourthline is dedicated to data-oriented decision-making, so we implemented a new analytics tracking tool: Snowplow SDK, v6.0.3.

We have also renewed our entire data pipeline.

Important

We will be implementing an extensive update of events emitted by our SDKs during July.
Stay tuned!

 Added

We added videos to illustrate the user experience of our solutions and modules via the App Drop-in and Web SDK.

App Drop-in

Improved

Qualified Electronic Signature

If the client leaves the signature flow, they can now re-enter the flow at the same place, instead of having to start a new flow.

Physical Proof of Address

The copy in this module now provides better guidance and improves the user experience.

Fixed

In the Android SDK, we fixed a navigation crash when initializing the drop-in, after building with AGP 8.4.x.

Web SDK

Improved

We released improvements to selfie capturing, which has increased selfie conversion by almost 7% for Android and low-end devices!!

AML Screening & Monitoring

Improved

We have improved our webhook notifications:

• You can update your configuration to be notified when a screening requires investigation: Status manualReviewRequired
  (This was already the case for AML Monitoring.)
• Notifications now include hits that are still awaiting investigation: Status pendingManualReview
• Notifications also return any relevant categories and subcategories.
  
  

Action

To update your AML Screening configuration to be notified when an investigation is required, contact your Fourthline delivery manager.

Case Review Portal

 Added

Quality Assurance

We're proud to introduce a new Quality Assurance functionality that lets your Compliance and QA teams flag process improvements and demonstrate evidence of compliance reviews to regulators and auditors.

Users with the QaAuditor role can create samples of completed cases for review, specifying the sample size and time period. Within cases, auditors can add comments on individual checks. Multiple auditors can collaborate on the same sample and track progress.

Action

To enable Quality Assurance, reach out to your Fourthline delivery manager.

Selfie video depth camera data

For the App Drop-in iOS SDK, we now collect depth camera data while recording the selfie video to help confirm liveness. This functionality uses Apple TrueDepth technology on every model later than iPhone X 2017, including iPhone 11 and higher, but excluding iPhones SE 2020 and SE 5G 2022.

Improved

Physical Proof of Address

In addition to performing eligibility checks and including the Physical Proof of Address document photo in the CDD zipfile, we now extract the following data from the document:

• Document type
• Issue date
• Validity in days, based on the document type
• Client's name
• Client's home address

We return this data in the CDD PDF, XML, and JSON formats.

Tax Number

For the Tax Number module, you can now configure which TIN documents to accept. If a client provides a document that is outside your regulatory scope, we don't return the TIN to you.

Support

For any questions, contact your Fourthline delivery manager.
For older notes, see the Release Notes Archive.

App Components

 Added

Introducing Fourthline App Components! If you build custom flows with your own UI, business logic, orchestration, reduce development time and effort with these standalone functionality modules for Android and iOS mobile apps.

Document Component

This component captures the document photos and video, with real-time feedback to the client, and extracts the data. It returns the photos, video, and data to you to upload to Fourthline via the API. We provide the UI, which you can customize in the same way as the App Drop-in. You can dynamically adjust the functionality, e.g. disable the tilted photo step.

Biometrics Component

This component captures the selfie photo and video, and functions the same way as the Document Component.

More information

For the full documentation, see App Components.

App Drop-in

Improved

You can now:

• Dynamically configure the minimum required age and related checks in the Identity Verification flow.
• Co-design Fourthline xcframeworks.

Web SDK

 Added

European markets have different rules for the Tax Number module: some require evidence, such as a photo of a second document, and some have different forms of TIN, such as the Spanish NIE, NIF, and DNI. Fourthline has extensive knowledge of local regulations and our SDKs offer custom flows per market.

Previously, the Web SDK only supported the Dutch BSN flow. It now supports all Spanish TINs and the Italian codice fiscale, in parity with the App Drop-in.

Action

To understand your market requirements and enable the Tax module, contact your Fourthline delivery manager.

Fixed

We fixed an issue where signed documents for Qualified Electronic Signature weren't available to download on some devices.

App Drop-in

 Added

As of May 1, 2024, Apple applies new third-party library requirements for all application owners on the App Store. For more information, see Apple Developer – Upcoming third-party SDK requirements.

Although Fourthline's iOS SDK itself isn't impacted, it uses 2 impacted libraries: Lottie and OpenSSL. Therefore we added a manifest file to the SDK, that explains which data points are used for what reason.

Action required

Update your iOS App to SDK version 2.37.3 or newer to fully comply with Apple's requirements.

Fixed

We fixed:

• Some issues related to extending the validity of French national ID cards
• The Unknown selfie error, which was mostly occurring on iPhone 12 mini devices

Web SDK

Improved

Permissions dialog

We improved conversion in the Location section of the Identity Verification flow. To access the client's device geolocation, they need to give both operating system (OS) and browser permissions, which are under the OS's jurisdiction. If the client initially blocks permission and then decides to unblock it (especially on iOS), they need to change the permission settings on their device. At this point, there was an increase in drop-outs.

• Before: On the Location access blocked screen, the client tapped the Learn more call-to-action (CTA) button, and an overlay containing the unblocking instructions opened. The client tapped X to close the overlay, changed the settings, and then tapped the Try again CTA button.

• Now: On the Location access blocked screen, the unblocking instructions are displayed in an accordion, providing a clear overview of the 2 steps involved. The client changes the settings and then taps the Try again CTA button.

Furthermore, the unblocking instructions for both the device's geolocation and camera are now contextual and match the client's OS and browser.

Qualified Electronic Signature flow

We improved the 409: Incorrect passcode error message.

Fixed

We fixed some errors in the German copy.

AML Screening & Monitoring

• We released new Get hits endpoints that provide more information about false positives and confirmed hits.
• You can now configure to screen clients by PEP, sanctions, adverse media, and convictions hits separately or a custom combination, instead of all together.
• We overhauled the backend to improve search accuracy, stability, and speed.

App Drop-in

Improved

Document NFC for Spanish documents

Document NFC is one of the most secure features of Fourthline's Document flow. For Spanish documents, we can now more easily unlock NFC chips using the card access number (CAN).

We then re-ordered the steps in the user journey, so that clients can choose:

• NFC flow: Scan the front and back of the card with NFC (42% shorter journey).
• Document scan flow: Take more document photos (front, front tilted, back, back tilted).

Click to magnify

Request feature

To enable Document NFC, contact your Fourthline delivery manager.

Web SDK

 Added

Physical Proof of Address

Physical Proof of Address is now available on Web SDK!

In this flow, the client:

1. Enters the Physical Proof of Address module
2. Selects the type of proof of address document
3. Chooses to upload a PDF file or photo of the document from their device, or to take a photo of the document now
4. Either selects a file or image to upload
5. Or, takes a photo of the document
6. Confirms the document photo

Request feature

To enable Physical Proof of Address for Web SDK, contact your Fourthline delivery manager.

Enable JS prompt

Previously, if the client had JavaScript disabled in their mobile web browser, the Web SDK couldn't load.
Now, the SDK detects this and the UI prompts the client to enable JavaScript to start the workflow.

Improved

Feature configuration

You can now configure to enable or disable the following features:

• Selfie video
• Tax Number extraction
• Tilted document photos

Configure features

To configure these features in your Web SDK implementation, contact your Fourthline delivery manager.

Lower minimum age

Previously, the minimum supported age was 18 years and is now 16 years.

Change configuration

To change your minimum age configuration to 16 years, contact your Fourthline delivery manager.

Case Review Portal

You can now set up access to the Case Review Portal via Okta Federation.
