v2.10.0​

Improvements​

  • Significant improvements in photocopy detection. Both the False Rejection Rate and False Acceptance Rate are reduced by ~50% as measured on the default match level.

Bug fixes​

  • Fix for duplicate attrs resource: attr/mb_onboardingImageColor when combining multiple Microblink's SDKs in the same app

Other changes​

  • Removed libc++_shared.so from the SDK

April 9, 2024

v2.9.3​

Bug fixes​

  • fixed Ping server URL error when using proguard-android-optimize.txt default proguard file

March 26, 2024

v2.9.2​

Bug fixes​

  • fixed URL of the server performing online license check when it's enabled
    • in v2.9.1 the URL depended on the BUILD_TYPE property, pointing to production server only when BUILD_TYPE was set to distribute. However, apparently the BUILD_TYPE is not a compile-time property on Android like it's on other platforms and native code, so it was affected by the setting of the app that was integrating the SDK and that caused the SDK to call to a dev server which is unavailable from the external network.

Other changes​

  • Add option to change Ping URL for Ping proxy feature through MicroblinkSDK.setPingProxyUrl()
  • minor improvements in the default UI w.r.t. accessibility

March 22, 2024

v2.9.1​

Minor API changes​

  • split up Image class to Image and InputImage
    • InputImage is to be used as an input to the recognizers. Image will be the result of recognizer processing
    • InputImage retains ROI functionality, but is now not serializable
    • InputImage handles YUV planes more efficiently
    • Image is now always BGRA and is serializable

Bug fixes​

  • removed UI thread blocking while waiting for recognition to complete
    • this fixes the ANR that can occur when the app gets resumed from the background on slow network connections when using online license keys
  • fix documentation-generated links to Javadoc
  • fixed crash that occurred when HDR image was provided as Bitmap to the Direct API
    • if provided Bitmap is not in ARGB_8888 config, it will be automatically converted into ARGB_8888 config
    • only if the conversion is not possible, then the exception will be thrown

Other changes​

  • native code is now built using NDK r26c and uses dynamic c++ runtime (libc++_shared.so)
    • in case when multiple different dependencies use the same runtime in the same app, the latest available version of the library should be packaged into the app
  • added support for license keys that support multiple application IDs
  • added android.permission.INTERNET permission to the manifest of LibBlinkCard
    • this permission is needed in order to correctly perform license key validation for licenses that require that

v2.9.0​

What's new in the BlinkCard Recognizer?​

  • Improved scanning performance and added support for virtually any card layout
  • Improved IBAN parser which now supports more IBAN formats
  • Added option allowInvalidCardNumber which allows reading invalid card numbers to avoid endless scanning on samples and test cards:
    • use with care as it might reduce accuracy in certain situations in production
    • for invalid card number the flag cardNumberValid in BlinkCardRecognizer.Result will be set to false

Improvements​

  • Better support for RTL languages in our default UX

Breaking API changes:​

  • Min Android SDK API level is raised to 21 (Android 5.0)
  • Removed legacy recognizers: LegacyBlinkCardRecognizer and LegacyBlinkCardEliteRecognizer

August 30, 2023

v2.8.1​

  • Fixed crashing issue when opening onboarding screens the help button

August 22, 2023

v2.8.0​

Improvements​

  • Included hand, photocopy, and screen detection models to achieve liveness functionality
  • Added anonymization info on which side was anonymized. String data is anonymized using an asterisk instead of blanking the result.
  • Expanded the number of supported credit card types by 100%.
  • Improved data extraction, including a 30% reduction in incorrect processing of CVV field.

What's new in the BlinkCard Recognizer?​

  • Added new settings handScaleThreshold, handDocumentOverlapThreshold, screenAnalysisMatchLevel, photocopyAnalysisMatchLevel. These settings are used in combination with the new liveness features.
  • Added a new callback LivenessStatusCallback, which is invoked when each side of a card is scanned. It is called with one parameter, a LivenessStatus enum. Use BlinkCardRecognizer.setLivenessStatusCallback method to set the callback.

BlinkCard Recognizer Result​

  • Two new booleans: firstSideAnonymized and secondSideAnonymized have been added to indicate whether the first or second side of the card has been anonymized, respectively.
  • New result documentLivenessCheck which has new liveness model results. It contains liveness information about the first and second sides of the card. Liveness information contains the results of checks performed on the card using screen detection, photocopy detection, and the presence of a live hand.

January 12, 2023

v2.7.0​

New features:​

  • Improved support for diverse credit card designs.

Architecture support:​

  • Devices that are based on the Intel x86 architecture, rather than ARMv7, are no longer supported. x86 and x86_64 architectures are used on very few devices today with most of them being manufactured before 2015, and only a few after that (e.g. Asus Zenfone 4). According to the Device catalog on Google Play Console, these devices make up about 1% of all Android devices (223 out of 22074 devices that have an API level of 21 and above support this architecture).

New user instructions that lead to successful scans​

  • More detailed instructions on how to scan credit cards, via an intro tutorial or tooltip during scanning, leading to improved success rates in credit card scanning and data extraction.

New layout for BlinkCardUISettings​

  • The scanning screen now shows a reticle in the center with scanning instruction.

What's new in the BlinkCard Recognizer?​

  • Added a new property fallbackAnonymization in AnonymizationSettings. If true, anonymization is applied on all fields of the image if extraction is uncertain.
  • Improved anonymization performance.

June 6, 2022

v2.6.0​

New features:​

  • We've added support for launching the scan activity via the new Activity Result API. Check out our sample to see how to implement it.

Improvements​

  • We’ve added support for 1000+ new credit card types.
  • Decrease of wrongly PAN field processing by 30% for horizontal credit cards, and by 60% for vertical credit cards.
  • Improvements in the Anonymization functionality for Quick Read formats on VISA credit cards, as well as general improvements for all other credit card types.

February 10, 2022

v2.5.2​

Visual identity update​

  • We’ve updated Microblink logo and colors

Fixes​

  • Fixed crash on some devices (mostly Huawei) when opening camera if SDK was used in full screen mode

December 21, 2021

v2.5.1​

  • Scanning improvements

November 12, 2021

v2.5.0​

Improvements and fixes:​

  • Improved date extraction from partial dates.
  • Fixed broken anonymization in result screen when the PAN number was anonymized but the image was not. We now correctly anonymize the image too.

Minor breaking API change​

  • We've changed how RecognizerRunner processes images. Now it can treat Image objects as either video frame or photo frame. Until now, Direct API always processed images as photo frames, that not giving ability to recognizers to use time-redundant information for yield better recognition quality.

August 20, 2021

v2.4.0​

Improvements and fixes:​

  • We updated the default BlinkCard scanning screen (BlinkCardOverlayController and BlinkCardActivity) which is activated when using BlinkCardUISettings. Now the UI supports landscape mode.
  • From now on, BlinkCard reads and extracts the expiry date in MM/YYYY format
  • We’ve fixed camera issues for the following devices:
    • Motorola Moto G100 - Camera 2 API wasn’t working
    • Realme X50 5G - Problem with Camera 2 API in legacy mode
    • LG K4 - Camera 2 API wasn’t working
    • Galaxy Tab Active 2 - broken aspect ratio

May 14, 2021

v2.3.0​

New features:​

  • We've added support for vertical payment cards.
  • As of this release, BlinkCard supports the Visa Quick Read format (the one where the card number spans through four lines).
  • We've changed the threshold for "Camera too far" and "Camera too near" callbacks. From now on, the card needs to be closer to the camera.

April 12, 2021

v2.2.0​

New features:​

  • We've added a new feature that lets you anonymize extracted results, images or both:
    • Choose which fields you want to mask:
      • Card number
      • Card number prefix
      • CVV
      • Owner
      • IBAN
    • Choose a BlinkCardAnonymizationMode for each field:
      • None
      • ImageOnly - Black boxes will cover chosen data on the extracted image, results are not anonymized
      • ResultFieldsOnly - String data is redacted from the result, images are not anonymized
      • FullResult - Both images and string data (results) are anonymized
    • You can customize the way you anonymize the card number through CardNumberAnonymizationSettings:
      • prefixDigitsVisible - Defines how many digits at the beginning of the card number remain visible after anonymization
      • suffixDigitsVisible - Defines how many digits at the end of the card number remain visible after anonymization

Improvements​

  • We've added support for new horizontal card layouts

February 22, 2021

v2.1.0​

New features:​

  • We’ve updated SDK's Android target API level to 30.
  • We’ve translated the complete SDK to the Serbian language.
  • We’ve made the SDK safe from tapjacking, a form of attack where a user is tricked into tapping something he or she didn’t intend to tap. We did this by adding a new security option that prompts the SDK to discard touches when the activity's window is obscured by another visible window. To activate it, use UISettings.setFilterTouchesWhenObscured(true).

Other improvements:​

  • We’ve updated our default UI with new error messages shown if the user doesn’t place the card within the frame.
  • We’ve updated security code field on the edit results screen, it is no longer anonymized.
  • We’ve added a new edit results screen customisation option, you can now change the toolbar icon (mb_blinkcardEditToolbarNavigationIcon theme attribute).
  • We've introduced other variants of resetRecognitionState methods that enable resetting of the current recognition step. Call RecognizerRunner.resetRecognitionState(false) when scanning with Direct API and RecognizerRunnerView.resetRecognitionState(false) when scanning with the camera to clear the scanning cache and results only for the current recognition step, for example, only for the backside of the document.

Minor API changes:​

  • We've replaced Using time-limited license! warning with Using trial license! warning. The warning message is displayed when using a trial license key. To disable it, use MicroblinkSDK.setShowTrialLicenseWarning(false).

Bug fixes:​

  • SDK does not require permission android.permission.ACCESS_NETWORK_STATE to unlock itself anymore, in cases when the license key needs online activation.
  • We have fixed an edit results screen issue causing user changes being lost when the app goes to background.
  • We've fixed the front camera error on Oukitel WP8 Pro.

v2.0.0​

BlinkCard v2 Release Announcement​

We're proud to announce our AI-driven BlinkCard v2.0! Extract the card number (PAN), expiry date, owner information (name or company title), IBAN, and CVV, from a large range of different card layouts.

As of this version, BlinkCard SDK is fully compatible with other Microblink SDKs, which means that you can use it with other Microblink SDKs in the same application.

  • BlinkCard v2.0 now supports card layouts with all information on the back side of the card!

  • BlinkCardRecognizer is a Combined recognizer, which means it's designed for scanning both sides of a card. However, if all required data is found on the first side, we do not wait for second side scanning. We can return the result early. A set of required fields is defined through the recognizer's settings.

  • "Front side" and "back side" are terms more suited to ID scanning. We start the scanning process with the side containing the card number. This makes the UX easier for users with cards where all data is on the back side.

  • We've expanded the set of possible recognizer states with StageValid. This state is set when first side scanning completes with valid data, and second side scanning is required.

  • Available BlinkCardRecognizer settings:

    • You can toggle mandatory extraction of all fields except the PAN.
    • You can enable the blur filter. When blur filtering is enabled, blurred frames are discarded. Otherwise, we process the blurred frames but set the blur indicator result member.
    • You can define required padding around the detected document. This ensures some empty space exists between the document and the edge of the frame.

  • BlinkCardRecognizer.Result structure:

    • Contains:
      • The card issuer
      • PAN
      • PAN prefix
      • Expiry date
      • Owner information
      • IBAN
      • CVV
      • Cropped document images
      • Blur indicators for both sides
      • Processing status
    • Processing status can be one of:
      • Success - if the process ended successfully and data is valid
      • DetectionFailed - if detection of the document failed
      • ImagePreprocessingFailed - if preprocessing of the image failed
      • StabilityTestFailed - if inconsistent results were detected between different video frames (when video processing, we require at least two frames with consistent data, for image processing this isn't applicable)
      • ScanningWrongSide - if the first side presented in the scanning process does not contain the PAN, or when the user failed to present the second side
      • FieldIdentificationFailed - if we detected a field, but we're unable to parse it (possible glare issues, or a finger covering the field)
      • ImageReturnFailed - failed to return requested images
      • UnsupportedCard - this card layout is currently unsupported.

New features:​

  • We added a new BlinkCard screen that allows users to edit BlinkCardRecognizer scan results:

    • This screen allows users to edit scanned data and input data that wasn't scanned.
    • Enable it by calling BlinkCardUISettings.setEditScreenEnabled(true).
    • Configure which fields should be displayed on this screen by using BlinkCardUISettings.setEditScreenFieldConfiguration() method.
    • Set your custom theme with BlinkCardUISettings.setEditScreenTheme() method.
    • Change default strings by using BlinkCardUISettings.setEditScreenStrings().
    • To get user-edited fields, in your onActivityResult(int requestCode, int resultCode, Intent data) method call BlinkCardEditResultBundle.createFromIntent(data).
    • This feature is available only for BlinkCardRecognizer.
    • If you are using a custom UI, you can launch edit screen by building intent with the following method BlinkCardEditActivity.buildIntent().

  • We updated the default BlinkCard scanning screen (BlinkCardOverlayController):

    • Instructions on how to reduce glare will be displayed when the user enables flashlight, you can disable it with BlinkCardUISettings.setShowGlareWarning(false).
    • If the edit screen is enabled, a new button will show up after 5 seconds of unsuccessful scanning to allow the user to go directly to the edit screen.

Other improvements:​

  • We have translated complete SDK to following languages: Arabic(UAE), Chinese simplified, Chinese traditional, Croatian, Czech, Dutch, English, Filipino, French, German, Hewrew, Hungarian, Indonesian, Italian, Malay, Portuguese, Romanian, Slovak, Spanish, Slovenian, Thai and Vietnamese.
  • We have improved recognition timeout logic when using BlinkCardRecognizer.
    • When a credit card has multiple sides to scan, the timeout timer for the second side starts after the second side of the card has been detected. Previously, it has been started immediately after the first side has been scanned.
    • Timeout duration can be configured by using RecognizerBundle.setNumMsBeforeTimeout

Major API changes:​

  • To ensure compatibility with other Microblink SDKs, we have repackaged all classes. We have renamed the root package com.microblink to com.microblink.blinkcard, which is unique to BlinkCard SDK.
  • ScanResultListener interface now has an additional method called when the scanning cannot continue because of an unrecoverable error. You have to implement the onUnrecoverableError method. If you’re using built-in activities, when onActivityResult is called with RESULT_CANCELED result code, the exception will be available via ActivityRunner.EXTRA_SCAN_EXCEPTION intent extra. If the user canceled the scan, the exception would be null.

Minor API changes:​

  • We have renamed old BlinkCardRecognizer and BlinkCardEliteRecognizer recognizers to LegacyBlinkCardRecognizer and LegacyBlinkCardEliteRecognizer. They are now deprecated.
  • We removed RecognizerRunnerView custom attributes: mb_initialOrientation and mb_aspectMode. Use RecognizerRunnerView.setInitialOrientation and RecognizerRunnerView.setAspectMode to configure the attributes in the code.
  • We renamed RecogitionMode to RecognitionDebugMode in RecognizerBundle.

Bug fixes:​

  • We fixed race conditions in camera management, which in some cases caused that the camera was unable to resume after it had been paused.
  • We fixed crash when using Direct API on high resolution com.microblink.image.Image from HighResImageWrapper

February 17, 2020
