We can generalize by mentioning that, when deciding which electronic signature system best suits the needs of a business, one should use traditional paper-based practices as a gold standard. If a specific technology mimics or matches these practices closely, it is probably a safe and reliable choice. The more technical shortcuts a system employs, such as creating multiple signatures with one stroke of a pen or keypad, or saving  images in place of real signatures, the more likely the system is to encounter difficulties and fraud in practice. With old ink-on-paper characteristics as one’s guide, electronic document solution should be a signature success.
