Passport Scanner #

Easily scan passports to extract its information from the MRZ code. This app is using the camera of the device to scan the MRZ region (Machine Readable Zone) and parse it to extract the information.

Setup #

Since this package is using ML Kit for text recognition, you must satisfy its requirements:

iOS #

• Minimum iOS Deployment Target: 15.5
• Xcode 15.3.0 or newer
• Swift 5
• ML Kit does not support 32-bit architectures (i386 and armv7). ML Kit does support 64-bit architectures (x86_64 and arm64). Check this list to see if your device has the required device capabilities. More info here.

Your Podfile should look like this:

platform :ios, '15.5'  # or newer version

...

# add this line:
$iOSVersion = '15.5'  # or newer version

post_install do |installer|
  # add these lines:
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=*]"] = "armv7"
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion
  end

  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    # add these lines:
    target.build_configurations.each do |config|
      if Gem::Version.new($iOSVersion) > Gem::Version.new(config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'])
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion
      end
    end

  end
end

Notice that the minimum IPHONEOS_DEPLOYMENT_TARGET is 15.5, you can set it to something newer but not older.

Android #

• minSdkVersion: 21
• targetSdkVersion: 35
• compileSdkVersion: 35

Supported languages #

The ML Kit Text Recognition API can recognize text in any Chinese, Devanagari, Japanese, Korean and Latin character set. Supported languages can be found here.

Camera permission #

There is no need to ask for the camera permission, this will be done automatically.

Usage #

You can add the PassportScannerWidget to your scaffold and pass a listener to get the result data:

Scaffold(  
  appBar: AppBar(title: Text('Passport Scanner')),  
  body: PassportScannerWidget(  
    onScanned: (result) {  
      print('Scanned: ${result.documentNumber}, ${result.givenNames} ${result.surnames}');
    },  
  ),  
)

The data will be an MRZResult object, and it includes these information:

documentType
countryCode
surnames
givenNames
documentNumber
nationalityCountryCode
birthDate
sex
expiryDate
personalNumber
personalNumber2
