interactions involving the general public, is handwritten signature devices and
software. While the use of any pen-and-tablet signature technology may seem to
be the logical replacement for traditional "wet" ink-on-paper
signatures, there are several issues to consider when choosing a system for
your business. Signature capture hardware manufacturers have their own
specifications, data formats, and software methodologies that affect security,
authentication, and legality.
