Pfizer pegs the cost of one "wet signature" at $30 (including time to track down the signer, plus storage and scanning costs, Holbrook says, though some analysts estimate the cost as high as $125.) Today, one smart card (and its unlimited number of digital signatures) costs $13 plus $70 for a three-year license for the {high-assurance} PKI credential (Pfizer uses a Microsoft digital certificate authority for some in-house signatures, but for signatures subject to outside scrutiny, it partners with Citibank to license the SAFE high-assurance PKI credential; SAFE—"signatures and access for everyone"—is a pharmaceutical industry consortium.) Anecdotally, Pfizer's use of FedEx to ship documents for signatures has also dropped, Potter says.
