A computerized signature is a legally valid digital representation of an individual’s handwritten signature. It is used to authenticate agreements and transactions in the digital world, much like a written signature would be used in the physical world. Essentially, computerized signatures are digital evidence of consent on certain documents—like contracts, invoices, and forms—a signee agrees to abide by the terms and conditions of those documents. By providing a secure, reliable identity solution, electronic signatures provide assurance when business is done online.
