This is new for me:
If I add a fillable pdf to my webpage for customers to fill out, is the information going to be secured once it is sent back to me?
It is is if you send it to a secured web server, running up to date software written by an experienced web programmer. Forget any ideal of emailing it though.
Thank you for your quick reply; just one more question as I am new to this process... If a customer fills out the PDF what is the best way to transfer the information, lets say to excel or what other application would I use to gather the information?
Well, it has to get to you securely. Often that goes into a database on the secure server. Otherwise typically you submit an FDF or XFDF file, which you can import to Acrobat to fill the form again. Hard work if you have a lot of submissions.
