How Do E-Signatures Work

What Is an Electronic Signature?

Electronic signatures are various legal software methods of authenticating digital documents. According to the Federal ESIGN Act of 2000, an electronic signature can be a symbol, a sound, or a digital process intentionally attached to a record by its owner. An e-sign can also be logically associated with the data in an electronic document and the signer rather than directly attached to a form. A properly used e-signature serves as a legal substitute for a conventional handwritten signature.

Using electronic signatures, you can sign a variety of contracts and agreements. Here are the types of documentation that are most often signed electronically:

  • Forms in banks
  • Non-disclosure and non-compete agreements;
  • Hiring contracts
  • Product releases
  • Rental agreements
  • Leases
  • Tax forms
  • Permission slips
  • Insurance documentation

E-signature methods are flexible enough to be integrated into any business and federal document flow. Any department can significantly improve workflow efficiency by implementing e-sign protocols in the right way.

There are some exceptions, though. Electronic signatures cannot be used for signing:

  • Court documentation;
  • Documents related to Uniform Commercial Code (UCC);
  • Wills (both for creation and execution);
  • Documents regulated by family lawn, such as divorce, marriage contract, or adoption;
  • Filing for bankruptcy.

Types of E-Signatures

As the interpretation of the electronic signature standard is open-ended, the market has come up with multiple types of e-signatures to cover the different demands of users. Some methods are more focused on security, while others offer faster workflow. Below are the most common types of e-signatures:

  • SES (Standard electronic signatures) – it’s the most widely accepted e-sign type that is mostly used in online signing. Unlike AES, it’s not encrypted with a cryptographic key and relies only on the user’s intention to sign a document. SES can be a scanned image of a signature or simply a tick in a checkbox on a website.
  • AES (Advanced electronic signatures) – it’s a more secure edition of SES as it requires signer authenticity verification prior to signing. In most cases, PKI (public key infrastructure) is used for that. This method is used for signing important business contracts, proposals, etc. This type is equivalent to a handwritten signature in the US but doesn’t have the same legal power in the EU.
  • QES (Qualified electronic signature) – this e-sgn type works only in the EU. It combines requirements for SES and AES and adds several custom requirements for qualified electronic signature input hardware. The combination of a protected e-sign device with AES protocols ensures 100% authenticity and signed document integrity. This type is highly effective against business contract fraud.
  • Wet signature – although wet signatures are not digital, they can be scanned and used as SES. Still, they are not considered as secure and legally forceful as fully digital signatures.

Benefits of Electronic Signatures

With businesses and government departments adopting cloud technologies and paperless workflows, e-signatures let you simplify your own document flow as well. An e-signed document can be instantly submitted and processed earlier than any posted paper form. It’s also fully protected from physical theft or loss on its way to the receiver. When you create an e-signature, you can quickly insert it into multiple forms at once.

The use of e-signature for your business will reduce the amount of paper in the office and help you establish relations with remote employees without the need to meet during the pandemic.

How Does E-Sign Work?

Digitized documents are used to reduce the amount of paper in workflows. E-signatures are needed to sign these documents. Depending on the document type and required security level, the document creator and signer agree to use a particular e-sign type (listed above). While SES is not encrypted, AES can be protected with a cryptographic key that is later verified by the receiver and executed.
