New fraud detection: BIN intelligence
BIN intelligence enhances payment risk assessment at the moment of card capture.
Real-time BIN lookup validates the PAN and returns detailed card information, including type, brand, category, issuing bank, and issuer country.
This additional fraud signal helps customers identify high-risk transactions early, before the transaction begins.
Architectural shift: session-based API
The legacy Recognizer architecture is deprecated. BlinkCard v3000 moves to a session-based model, decoupling scanning logic from the UI lifecycle and enabling a headless integration for custom implementations.
Epoch versioning scheme
We are moving to an Epoch-based versioning system: (EPOCH * 1000 + MAJOR).MINOR.PATCH. This new versioning makes it easier for customers to immediately identify the impact of an update and plan upgrades with confidence.
- EPOCH: Fundamental architectural rewrites.
- MAJOR: Breaking API changes.
- MINOR: New features, backward-compatible.
- PATCH: Bug fixes.
Other improvements
- i18n: Expanded localization support to better serve a global user base: we added 33 new languages, bringing the total supported languages to 56, enabling a more convenient user experience across diverse regions.
- a11y: Enhanced accessibility capabilities, including support for screen readers.
- We introduced more granular event tracking throughout the SDK lifecycle, enabling customers to gain deeper insights into success rates and drop-off points during scanning sessions. These enhanced analytics help identify optimization opportunities and ensure an improved, more reliable user experience.
- Improved photocopy detection model, reducing FAR@FRR of 1% from 27.53% to 13.69%, significantly enhancing reliability.
Highlights & integration improvements
- Lighter SDK: By incorporating dynamic model loading, BlinkCard v3000 drastically reduces download size from ~11MB to ~3.8MB, and lowers memory usage.
- Unified session-based API: We've moved away from recognizer-approach to a single session-based BlinkCardScanningSession, unifying scanning logic under one simplified API.
- Backward compatibility: Existing production keys will continue to work with v3000.0. No new license key is required for the upgrade.
- More maintainable codebase: This new architecture sets the stage for easier and faster updates.
- Updated minimum OS requirement: BlinkCard SDK now requires Android API level 24 (Android 7.0 Nougat) or newer. This update allows us to leverage modern development practices, improve stability, and streamline future updates.
Architecture changes
- New core components: Instead of Recognizer-based architecture, BlinkCard uses a streamlined Session-based approach.
- Modern Kotlin features: Written fully in Kotlin, the code is simple and easy to work with, while still supporting Java integration.
- Jetpack Compose UI & modular SDK:
- UI is now built with Jetpack Compose, simplifying integration via
blinkcard-ux. - The SDK is modular:
blinkcard-corefor scanning logic.blinkcard-uxfor prebuilt UI components.
- UI is now built with Jetpack Compose, simplifying integration via
- Simplified flow: More straightforward API with clearer separation of concerns.
Major API changes
-
Simplified initialization & result handling
- New SDK initialization method:
BlinkCardSdk.initializeSdk(BlinkCardSdkSettings(licenseKey))
- Results are now retrieved through structured session-based callbacks instead of recognizer bundles.
- New SDK initialization method:
-
Enhanced UI customization & source-available UX
UiSettingsenables direct customization of typography, colors, and strings.- The source-available UI layer allows advanced modifications for branding and accessibility.
