Dynamsoft MRZ Scanner React Native SDK - Release Notes

3.4.1310 (05/20/2026)

Fixes & Improvements

  • Improved compatibility with devices running kernels that use a 16 KB memory page size.
  • Addressed intermittent crash and hang conditions encountered in certain runtime scenarios.

3.4.1300 (04/28/2026)

New

  • Image results: MRZScanResult now returns captured images alongside the parsed MRZ data. Five new properties are exposed on the result, each typed as ImageSourcePropType so it can be passed directly to a React Native <Image> element via its source prop:
    • mrzSideDocumentImage — a cropped and perspective-corrected image of the side containing the MRZ. Returned by default.
    • oppositeSideDocumentImage — a cropped and perspective-corrected image of the reverse side, relevant for two-sided documents such as TD1 ID cards. Returned by default.
    • mrzSideOriginalImage — the raw full-frame camera image captured for the MRZ side. Disabled by default.
    • oppositeSideOriginalImage — the raw full-frame camera image captured for the opposite side. Disabled by default.
    • portraitImage — the detected portrait extracted from the document. Returned by default.
  • Image return configuration: Added three new MRZScanConfig properties to control which images are included in the scan result:
    • returnDocumentImage (default: true)
    • returnOriginalImage (default: false)
    • returnPortraitImage (default: true)
  • Additional MRZ data fields: MRZData now exposes the following additional parsed fields:
    • issuingStateRaw — the raw ICAO issuing state code as encoded in the MRZ, before standardization.
    • nationalityRaw — the raw ICAO nationality code as encoded in the MRZ, before standardization.
    • optionalData1 — the first optional data field on the MRZ document.
    • optionalData2 — the second optional data field on the MRZ document.
    • personalNumber — the personal number field, typically present on TD1 and TD3 documents.
  • New UI button visibility controls: Added three new MRZScanConfig properties to control the visibility of toggle buttons in the scanning UI:
    • isBeepButtonVisible — shows or hides the beep sound toggle button (default: true).
    • isVibrateButtonVisible — shows or hides the vibration toggle button (default: true).
    • isFormatSelectorVisible — shows or hides the document format selector at the bottom of the scanning UI (default: true).

Highlighted Features

  • Updated the underlying Capture Vision bundle to 3.2.3000 for major improvements in reading accuracy and speed.
  • Neural MRZ Localization – The new MRZLocalization model improves region detection accuracy and delivers up to 42.7% faster processing for MRZ-based document workflows.
  • Configurable Localization Control – The new LocalizationModes parameter allows configuration for text line detection.

3.0.5200 (08/28/2025)

This is the introductory version of the MRZ Scanner (React Native Edition) to include the newly designed and developed ready-to-use MRZScanner component.
