As for fax and e-mail, I believe that those methods of transmission are less susceptible to fraud than ordinary mail because they leave digital signatures. If fraud is suspected, it's easy to trace the submission back to the source. Moreover, because the same official form must be used no matter how the application is submitted, I don't believe that fax and e-mail use will increase the number of fraudulent submissions from groups like ACORN. The time-consuming part of the process is filling out the form, which is the same in all instances.
