# Introduction

BlinkCard extracts information from credit and payment cards. 

It's available as an SDK and 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 a large number of credit and payment cards.

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