Question

How to disable signature verification/validation.

The platform I'm working with is Adobe Acrobat Pro 11.

     The forms that my place of employment uses require signatures from the client and our representative. We are using an Ipad on the field to present forms and obtain signatures from clients. The forms once singed are emailed to ourselves so that we can store them in our server. The problem we have encountered is that once the documents is signed and we try to open it on our PCs (windows) we get the infamous message- "At least one signature is invalid..."  Our agency does not need the signature to be certified or validated, all we require is that the signature be carried over digitally with the form so we can keep in our records. Is there a way around this problem? I have searched on the forum for an answer but I haven't found one yet.

Thank you.

Hi,

i'm bringing this old one up because i ran into the same mistake as chaye28.

Now my Problem is that i have about 50 filled forms including an signature field wich cannot be flattend due to the invalid signature.

Is there any way to remove the Signatur from the documents so i can flatten it? Or maybe a tool that doesn't care an flattens them anyway?

Regards Nic

Could you send it back to your iPad and send a flattened copy with PDF Expert 5?

Thank you for all of your help with this problem. I ended up deleting all signature fields on my forms and using the signature feature on PDFExpert. This is working out great for our purposes.

How exactly are you signing on an iPad? Adobe Reader for iOS doesn't support digital signatures, so I'm wondering what does.

I forgot to mention that on the ipad we are using PDF Expert to open, fill and sign all of our forms. It is unfortunate that that feature cannot be turned off. Now, how would i go about validating a signature? I don't understand what it is that i need to do.

thank you for all your help

Is the document digitally signed or Reader-enabled prior to it being e-signed with PDF Expert?

The warning is a security feature so you cannot just turn it off.

Adding the digital ID(s) that created the self-signed identities to your trust list will stop the message appearing for that specific ID, but you cannot choose to globally trust all self-signed IDs.
