How can customers sign pdf document in web browser?

[KathyPerry]

I created a document in InDesign, added fillin fields, including Digital ID field, in Adobe Acrobat Pro DC, Reader extended when saving it and loaded it to the web. When clients open the form online, all the fillin fields show up EXCEPT the digital signature field. Why can they not sign the document when it's open in a web browser? I'm dealing with all levels of tech-users so am trying to make this as easy as possible for them. Requiring every customer to download Reader and set up a digital ID is not feasible. Does Adobe suggest any other options for easily adding electronic signatures to documents online? Thanks very much for your help. -Kathy

They need to use Adobe technology.  Unfortunately almost all browsers block that and use their own basic form filling stuff, without signing options. You can't change this. Indeed, even if you could, if you aren't willing to have users download Adobe tech, how could this solve it?  I wonder though if you've looked at Adobe Sign? I haven't used it but it might be more what you want.
