There is no escaping the rapid advance of technology. People are interacting in ways that would have been completely alien to businesses and their employees just decades ago. Keeping in step with technological innovation, people are always seeking easier and faster ways to carry out their business. Doing business with people all over the country leaves little room for physical documents, or the signatures that are commonly used on them.
The electronic signature is commonplace now, but there is still concern about just how valid they are. Would they be legally binding in court, for example? According the the law in Australia, electronic signatures are in fact considered valid for signing agreements. Trouble arises when it becomes difficult to identify who actually signed a contract, or whether they were aware of the implications of signing. There are special tools that can identify the parties, and these can help to reduce the risk of a signature being declared invalid in court.
