Extract specific fields

The top-level result object contains aggregated fields extracted from all scanned sides of the document. All fields are optional—the SDK only populates what it can read from the document. Always check whether a field is present before using its value.

Name fields​

blinkId.addOnResultCallback((result) => {
  console.log("First name:", result.firstName?.latin?.value);
  console.log("Last name:", result.lastName?.latin?.value);
  console.log("Full name:", result.fullName?.latin?.value);

  void blinkId.destroy();
});

Date of birth​

Date fields carry both a structured representation (year, month, day) and the original string as it appeared on the document.

blinkId.addOnResultCallback((result) => {
  const dob = result.dateOfBirth;
  if (dob) {
    console.log("Year:", dob.year);
    console.log("Month:", dob.month);
    console.log("Day:", dob.day);
    console.log("Original string:", dob.originalString?.latin?.value);
  }

  void blinkId.destroy();
});

Document number and expiry​

blinkId.addOnResultCallback((result) => {
  console.log("Document number:", result.documentNumber?.latin?.value);

  const expiry = result.dateOfExpiry;
  if (expiry) {
    console.log("Expiry year:", expiry.year);
    console.log("Expiry month:", expiry.month);
    console.log("Expiry day:", expiry.day);
  }

  console.log("Permanent:", result.dateOfExpiryPermanent);

  void blinkId.destroy();
});

Address​

blinkId.addOnResultCallback((result) => {
  console.log("Address:", result.address?.latin?.value);
  console.log("Additional address:", result.additionalAddressInformation?.latin?.value);

  void blinkId.destroy();
});

Nationality, sex, and ethnicity​

blinkId.addOnResultCallback((result) => {
  console.log("Nationality:", result.nationality?.latin?.value);
  console.log("Sex:", result.sex?.latin?.value);
  console.log("Ethnicity:", result.ethnicity?.latin?.value);

  void blinkId.destroy();
});
