Not that wikipedia is an authoritative legal source, but the link below certainly reflects my understanding that Electronic signatures, even "scanned" signatures are legally binding and hold up in court. Using a tablet that can capture some level of pressure/etc during the signing process increases its identity.

IANAL, but there is more involved in contract law than proving the identity of the signature. Intent, business relationship, phone conversations, payment, signatures all hold sway. Forgery is not a new problem. In a perfect world, we would all be running around with third-party validated certificates that we could control at will, but we are not there yet? It seems that the law recognizes this?

Is there a particular vertical market where scanned signatures don't work?

Wherever the signature image can be legally disputed and challenged by the
customer.
