Description: Overview of BlinkID SDK for extracting data from 3000+ identity documents worldwide
---

# Introduction

BlinkID extracts information from identity documents. 

It's available as an SDK or as an API.

When used as an SDK integrated in your app, all extraction happens locally; no data leaves the device.

When used as an API, you self-host our Docker image. 
You send images to it and get extraction results in the response.

We [support](https://microblink.com/resources/full-list-of-supported-identity-documents/) over 2,500 identity documents from more than 140 countries.

You can use our pre-built scanning components to ensure a great user experience in your app.
