Passport OCR Node.js

The Node.js OCR SDK supports the passport API for extracting data from passports.

Using this sample passport below, we are going to illustrate how to extract the data that we want using the OCR SDK.
sample passport

Quick Start

const mindee = require("mindee");
// for TS or modules:
// import * as mindee from "mindee";

// Init a new client
const mindeeClient = new mindee.Client({ apiKey: "my-api-key" });

// Load a file from disk and parse it
const doc = mindeeClient.docFromPath("/path/to/the/file.ext");
const respPromise = doc.parse(mindee.PassportV1);

// Print a summary of the parsed data
respPromise.then((resp) => {
  if (resp.document === undefined) return;

Field Objects

Each Field object contains at a minimum the following attributes:

  • value (string or number depending on the field type):
    Corresponds to the field value. Can be null if no value was extracted.
  • confidence (Float):
    The confidence score of the field prediction.
  • bbox (Array< Array< Float > >):
    Contains exactly 4 relative vertices coordinates (points) of a right rectangle containing the field in the document.
  • polygon (Array< Array< Float > >):
    Contains the relative vertices coordinates (points) of a polygon containing the field in the image.
  • reconstructed (Boolean):
    True if the field was reconstructed or computed using other fields.

Extracted Fields

Depending on the field type specified, additional attributes can be extracted from the Passport object.

Using the above passport example, the following are the basic fields that can be extracted.


  • orientation (Orientation): The orientation field is only available at the page level as it describes whether the page image should be rotated to be upright.

If the page requires rotation for correct display, the orientation field gives a prediction among these 3 possible outputs:

  • 0 degrees: the page is already upright
  • 90 degrees: the page must be rotated clockwise to be upright
  • 270 degrees: the page must be rotated counterclockwise to be upright
// Show the orientation of each page
resp.pages.forEach((page) => {

Birth Place

  • birthPlace (Field): Passport owner birthplace.
const birthPlace = resp.document.birthPlace.value


const country =


Date fields:

  • contain the date_object attribute, which is a standard Ruby date object
  • can contain the raw attribute, which is the textual representation found on the document.
  • have a value attribute which is the ISO 8601 representation of the date, regardless of the raw contents.

The following date fields are available:

  • expiry_date: Passport expiry date.
const expiryDate = resp.document.expiryDate.value
  • issuance_date: Passport date of issuance.
const issuanceDate = resp.document.issuanceDate.value
  • birth_date: Passport's owner date of birth.
const birthDate = resp.document.birthDate.value


  • gender (Field): Passport owner's gender (M / F).
const gender = resp.document.gender.value

Given Names

  • givenNames (Array< Field >): List of passport owner's given names.
// To get the list of names
resp.document.givenNames.forEach((name) => {


  • id_number (Field): Passport identification number.
const idNumber = resp.document.idNumber.value

Machine Readable Zone

  • mrz1 (Field): Passport first line of machine-readable zone.
const mrz1 = resp.document.mrz1.value
  • mrz2 (Field): Passport second line of machine-readable zone.
const mrz2 = resp.document.mrz2.value
  • mrz (Field): Reconstructed passport full machine-readable zone from mrz1 and mrz2.
const mrz = resp.document.mrz.value


  • surname (Field): Passport's owner surname.
const surname = resp.document.surname.value
