#### Data extracted

The extracted data is returned in a structured and standardized format.

It includes fields from the **Visual Inspection Zone (VIZ)**, **Machine Readable Zone (MRZ)**, and **barcodes**.

The service will also extract images from the document, including **cropped faces**, **signatures**, **security elements**, and more.

#### Common use cases

Autofill is commonly used in scenarios such as:

* **Onboarding form autofill**: Prefill registration and onboarding forms directly from ID document scans to reduce manual entry and customer drop-off.
* **Data quality improvement**: Extract names, dates of birth, document numbers, and other key attributes directly from identity documents to minimise input errors.
* **Faster customer verification**: Reduce onboarding friction by automatically populating required identity fields during verification flows.
