Apparently, digital signatures and electronic signatures are different. I recall when we first started faxing scripts several area pharmacies wouldn't take it. Now, I can pressure my patients to go elsewhere, but in the end I can't just tell Rite Aid, I won't use them. So, they tell me that Electronic Signature below the name as is the default in AC scripts wouldn't work, but it had to say Digitally signed by... OK stupid. Then one of my MAs came up with a brilliant workaround. She changed my name in my user account from Bert Adams, MD to:
First name: Digitally signed by Bert Last name: Adams MD
This, of course, came out:
Digitally signed by Bert Adams, MD
Still had the electronic signature in place below. And, it looked funny on the letters, but who cares. Now the irony is now that I am using ePrescribe, and I only fax a few, they all go through even with just my name being the old way.
Technically, true digital signatures are ones with private keys and public keys and certificates and the like. But, that takes both sides having them. Right.
It is quite easy to make a stamp for AC or PDFs, etc. I don't know how Paperport does it. But, if you make a stamped signature for a PDF by just scanning it in, it will likely work, but you risk having the issue of the white background.
If you make a transparent stamp, then you don't have to worry about the white background covering anything up. In fact, I go out of my way to make sure it overlaps things.
