Capturing an Onscreen Signature

As per my knowledge there is no OOTB feature nor any shared component for your above mentioned requirement. But there is a shared component to sign PDF document. Please have a look.

This is indeed possible. You can use the a!FileUpload component. On a mobile device, when you select the button to choose a file, you will have the option to "draw signature".

Hi Eliot,
I tried this component but I am not seeing option to draw signature. Am I missing something here? Below is the steps I tried:
1. Created a fileUploadfield Component and then tried accessing that from my iphone. I am not seeing any option to draw signature.

Thank you in advance,

Hi surendrab - You will need to access the form via the Appian app, this is the only way to view the signature option.

Hi Brad,
Thank you so much for the reply. When you say Appian app, do I need to install the app to the phone first? How do I do that?
Thank you in advance,

Yes, you need to go to the Apple or Google app store, download the free Appian app (just search for Appian) and then login to your Appian instance from the app. You will then find your task, and the signature option will appear on your a!fileUpload component.

Got it. Thank you so much.

HI gangd

you can capture signature from moble appian app.
through file upload field in the form.
