Hello, I’m seeking your guidance on whether we can develop an application using the Backendless system. Specifically, I’d like to inquire about incorporating functionalities such as e-signature, document scanning using the device camera, and automatically creating PDF documents from user-entered information. Could you please advise if these functionalities are built into the Backendless system, or would we need to implement them independently? Your insights are highly valued. Thank you!
Hello @Sayali_Shinde ,
we do have a component for signature:
# Signature Pad
This is a component for Backendless [UI-Builder](https://backendless.com/developers/#ui-builder) designer based on the [signature_pad](https://github.com/szimek/signature_pad) library post by [Szymon Nowak](https://github.com/szimek).
The component allows to draw smooth signatures and save them for later usage. A user can pick up any color for a drawing pen. Also, the component has features for exporting signatures as images in different formats. The action buttons are configurable, and thus you can adjust their visibility and labels.

Other functionalities you will need to implement independently.
