Passport - India OCR

Mindee’s Passport - Indian OCR API uses deep learning to automatically, accurately, and instantaneously parse your documents details. In a few seconds, the API extracts a set of data from your PDFs or photos of indian passport, including:

• Page Number

• Country Code

• Identity Number

• Given Name(s)

• Surname

• Date of Birth

• Place of Birth

• Place of Issue

• Gender

• Issuance Date

• Expiry Date

• MRZ Row #1

• MRZ Row #2

• Name of legal guardian

• Name of spouse

• Name of mother

• Old passport date of issue

• Old passport number

• Address line #1

• Address line #2

• Address line #3

• Old passport place of issue

• File number

The Passport - Indian OCR API only supports two pages of Indian passports. The passports from other nationalities and states are not supported with this model, you can use International Passport API instead.

Set up the API

Create an API key

To begin using the Mindee V1 OCR API, your first step is to create your V1 API key.

1. To test your API, you can use the sample document provided below.

   

   
2. Access your Passport - Indian API by clicking on the corresponding product card in the Document Catalog

   
3. From the left navigation, go to documentation > API Reference, you'll find sample code in popular languages and command line.

from mindee import Client, AsyncPredictResponse, product

# Init a new client
mindee_client = Client(api_key="my-api-key-here")

# Add the corresponding endpoint (document). Set the account_name to "mindee" if you are using OTS.
my_endpoint = mindee_client.create_endpoint(
    account_name="mindee",
    endpoint_name="ind_passport",
    version="1"
)

# Load a file from disk
input_doc = mindee_client.source_from_path("/path/to/the/file.ext")

# Parse the file.
# The endpoint must be specified since it cannot be determined from the class.
result: AsyncPredictResponse = mindee_client.enqueue_and_parse(
    product.GeneratedV1,
    input_doc,
    endpoint=my_endpoint
)

# Print a brief summary of the parsed data
print(result.document)

# # Iterate over all the fields in the document
# for field_name, field_values in result.document.inference.prediction.fields.items():
#     print(field_name, "=", field_values)

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-here" });

// Load a file from disk
const inputSource = mindeeClient.docFromPath("/path/to/the/file.ext");

// Create a custom endpoint for your product
const customEndpoint = mindeeClient.createEndpoint(
  "ind_passport",
  "mindee",
  "1" // Defaults to "1"
);

// Parse the file asynchronously.
const asyncApiResponse = mindeeClient.enqueueAndParse(
  mindee.product.GeneratedV1,
  inputSource,
  { endpoint: customEndpoint }
);

// Handle the response Promise
asyncApiResponse.then((resp) => {
  // print a string summary
  console.log(resp.document.toString());
});

)

# Print a full summary of the parsed data in RST format

• Replace my-api-key-here with your new API key, or use the "select an API key" feature and it will be filled automatically.

• Copy and paste the sample code of your desired choice in your application, code environment or terminal.

• Replace /path/to/my/file with the path to your document.

• Replace my-api-key-here with your new API key, or use the select an API key feature and it will be filled automatically.

• Copy and paste the sample code of your desired choice in your application, code environment, terminal etc.

• Replace /path/to/the/file.ext with the path to your input document.

Remember to replace with your V1 API key.

1. Run your code. You will receive a JSON response with your document details.

You can find the prediction within the prediction key found in document > inference > prediction for document-level predictions: it contains the different fields extracted at the document level, meaning that for multi-pages PDFs, we reconstruct a single object using all the pages.

Each predicted field may contain one or several values including:

• a polygon highlighting the information location

• a page_id where the information was found (document level only)
