Release Notes for MAUI SDK - 3.x

3.4.1200 (04/17/2026)

New

  • Image results: MRZScanResult now returns captured images alongside the parsed MRZ data. Three types of images can be retrieved from the result:
    • Document image: A cropped and perspective-corrected image of the document, available via GetDocumentImage(EnumDocumentSide). Returned by default.
    • Original image: The raw full-frame camera image captured at the moment of scanning, available via GetOriginalImage(EnumDocumentSide). Disabled by default.
    • Portrait image: The detected portrait extracted from the document, available via GetPortraitImage(). Returned by default.
    • For two-sided ID cards, images for both sides are accessible by passing EnumDocumentSide.MRZ or EnumDocumentSide.Opposite to GetDocumentImage() and GetOriginalImage().

  • New EnumDocumentSide enumeration: Added EnumDocumentSide with values MRZ (the side containing the MRZ) and Opposite (the reverse side) to identify which side of a document an image belongs to.

  • Image return configuration: Added three new MRZScannerConfig 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 issuing state value as encoded in the MRZ, before standardization.
    • NationalityRaw — the raw nationality value as encoded in the MRZ, before standardization.
    • OptionalData1 — the first optional data field (nullable).
    • OptionalData2 — the second optional data field (nullable).
    • PersonalNumber — the personal number field, typically present on TD3 passport documents (nullable).
  • New UI button visibility controls: Added three new MRZScannerConfig 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).
