Electronic signature (Esignature) is not a new concept in business practice. In fact, telegraph signatures were once legally acceptable. Times have changed, of course. Even the traditional wet signature seems to be a thing of the past for many companies. In mid-2000, eSignature was ruled by Congress to ensure the same legal standing as a traditional handwritten signature. ESign even has its own national holiday, June 30th, if you plan to mark it on your calendar.
