# Python
engine_instance = ocrstudiosdk.OCRStudioSDKInstance.CreateFromPath(<PATH_TO_CONFIGURATION_FILE>)
session = engine_instance.CreateSession(<SIGNATURE>,
  "{\"session_type\": \"document_recognition\", \"target_group_type\": \"default\", \"target_masks\": \"chn.passport.*\"}")
image = ocrstudiosdk.OCRStudioSDKImage.CreateFromFile(<PATH_TO_IMAGE>)
session.ProcessImage(image)

result = session.CurrentResult()
target = result.TargetByIndex(0)
item_it = target.ItemsBegin('string')
while not item_it.IsEqualTo(target.ItemsEnd('string')):
  name = item_it.Item().Name()
  value = it.Item().Value()
  item_it.Step()

// Java
OCRStudioSDKInstance engine_instance = OCRStudioSDKInstance.CreateFromPath(<PATH_TO_CONFIGURATION_FILE>);
OCRStudioSDKSession session = engine_instance.CreateSession(<SIGNATURE>,
  "{\"session_type\": \"document_recognition\", \"target_group_type\": \"default\", \"target_masks\": \"chn.passport.*\"}");
OCRStudioSDKImage image = OCRStudioSDKImage.CreateFromFile(<PATH_TO_IMAGE>);
session.ProcessImage(image);
OCRStudioSDKResult result = session.CurrentResult();
OCRStudioSDKTarget target = result.TargetByIndex(0);
for (OCRStudioSDKItemIterator item_it = target.ItemsBegin("string"); !item_it.IsEqualTo(target.ItemsEnd("string")); item_it.Step()) {
  String name = item_it.Item().Name()
  String value = item_it.Item().Value()
  }

// C#
ocrstudio.OCRStudioSDKInstance engine_instance = ocrstudio.OCRStudioSDKInstance.CreateFromPath(<PATH_TO_CONFIGURATION_FILE>);
ocrstudio.OCRStudioSDKSession session = engine_instance.CreateSession(<SIGNATURE>,
  "{\"session_type\": \"document_recognition\", \"target_group_type\": \"default\", \"target_masks\": \"chn.passport.*\"}");
ocrstudio.OCRStudioSDKImage image = ocrstudio.OCRStudioSDKImage.CreateFromFile(<PATH_TO_IMAGE>);
session.ProcessImage(image);

ocrstudio.OCRStudioSDKResult result = session.CurrentResult();
ocrstudio.OCRStudioSDKTarget target = result.TargetByIndex(0);
for (OCRStudioSDKItemIterator item_it = target.ItemsBegin("string"); !item_it.IsEqualTo(target.ItemsEnd("string")); item_it.Step()) {
  String name = item_it.Item().Name();
  String value = item_it.Item().Value();
  }

// C++
std::unique_ptr<ocrstudio::OCRStudioSDKInstance> engine_instance(ocrstudio::OCRStudioSDKInstance::CreateFromPath(<PATH_TO_CONFIGURATION_FILE>));
std::unique_ptr<ocrstudio::OCRStudioSDKSession> session(engine_instance->CreateSession(<SIGNATURE>,

std::unique_ptr<ocrstudio::OCRStudioSDKImage> image(ocrstudio::OCRStudioSDKImage::CreateFromFile(<PATH_TO_IMAGE>));
session->ProcessImage(*image);
const ocrstudio::OCRStudioSDKResult& result = session->CurrentResult();
const ocrstudio::OCRStudioSDKTarget& target = result.TargetByIndex(0);
for (auto item_it = target.ItemsBegin("string"); item_it != target.ItemsEnd("string"); item_it.Step()) {
  string name = item_it.Item().Name();
  string value = item_it.Item().Value();
  }

Frequently Asked Questions

What is Passport OCR SDK?

Passport OCR SDK is an advanced solution for automated passport scanning and authentication. It captures and structures passport data using OCR and machine-readable zone recognition, supports NFC passport reading, and enables fast integration into mobile, desktop, server, and web environments.

Which passport types does OCR SDK support?

OCR SDK supports passports issued in 250+ countries and territories, allowing to create a global KYC platform for international identity verification. The solution scans ordinary, biometric, electronic, diplomatic, temporary, and other passport types, including MRP, MRTD, and eMRTD formats. OCR SDK correctly recognizes passports compliant with both legacy and new-generation ICAO/ISO standards.

How does OCR SDK enhance regulatory compliance?

Passport OCR SDK enhances regulatory compliance through on-premise / on-device data processing. Passport images and extracted personal data can be processed directly on the user’s device or within the company’s secure infrastructure, helping businesses meet GDPR, CCPA, and local data privacy standards, which is relevant for building KYC for emerging markets.

Are passport images sent to external servers?

No. On-premise OCR SDK does not require passport images to be sent to external servers, clouds, or crowdsourcing platforms for processing. The system runs directly on mobile devices, desktops, or company’s servers, ensuring full data locality and reducing privacy and security risks.

How does OCR SDK detect forged passports?

ID verification SDK detects forged passports using advanced document forensics technologies. The system spots digital image tampering, deepfakes, morphed passport photos, photocopied IDs, screen recapture attempts, and other signs of manipulation. Passport OCR SDK also validates document authenticity through machine-readable zone verification, NFC passport reading, and cross-checking of passport data.

Why is passport data cross-validation essential?

Passport data cross-validation helps confirm that all document zones contain consistent information. OCR SDK compares data from the visual inspection zone, machine-readable zone, and RFID/NFC chip to detect mismatches that may indicate document manipulation.

Does OCR SDK handle poor-quality images?

Yes. Passport OCR SDK is designed for real-world scanning conditions and can recognize passports with glares and blurs under low light and challenging capture angles. The system also performs preliminary image quality analysis during document capture to maintain high recognition accuracy and a low false acceptance rate.

Which platforms support Passport OCR SDK?

Passport OCR SDK runs on Android, iOS, Windows, Linux, and in web browsers through the WebAssembly technology. The solution enables precise document processing across all platforms. Developers can integrate it using C++, C#, Java, Python.
