Privacy concerns continue to influence the decision-making process when choosing how to sign documents electronically. The reliability and clarity of the signatures are also important, as is the speed with which documents can be processed. As digital signatures become standard practice, the variety and sophistication of online services available seem to be growing, reflecting user demand for faster and more secure document handling.
