A simple electronic signature is the most basic type of esignature. It is a scanned image of your handwritten signature or typed name.

2. Advanced electronic signatures (AES)

An advanced electronic signature is a more secure type of esignature. It uses biometrics to verify the signer’s identity.

3. Qualified electronic signatures (QES)

A qualified electronic signature is the most secure type of esignature that uses digital certificates for verification. A QES is typically used for financial transactions and other high-value contracts.

Why Do I Need to Use Electronic Signatures?

Here are the qualities that explain the growing popularity of esignatures across a wide range of industries:


Electronic signatures simplify the process of signing documents. They can help speed up business workflows by eliminating the need to print, sign, and scan documents.

Electronic signatures have been legally recognized in the United States since June 2000. The E-Sign Act and the Uniform Electronic Transactions ACT have established that esignatures are just as legally binding as their ink-based counterparts.

Electronic signatures carry the same weight and authority as physical ones for all other purposes. They are a valuable asset in any business agreement because they save time.


Esignature apps and services use a variety of methods to protect you from tampering, forgery, and identity theft. Some use biometrics, like a fingerprint or iris scan, to verify the identity of the signer. Others use digital certificates to verify the authenticity of signatures.

FAQs About Esignatures

Are electronic signatures and digital signatures the same?

While these terms are often interchanged, they are not strictly the same. The US Electronic Signatures in Global and National Commerce (E-Sign) Act defines an esignature as an “electronic sound, symbol, or process attached to, or associated with, a contract or other record and adopted by a person with the intent to sign a record.”

On the other hand, a digital signature is a technology that is used to encrypt and decrypt signatures. This is used in electronic signature solutions to verify the identity of the signer and to ensure that the document hasn’t been tampered with.

Can I use an electronic signature on any document?

No. Certain documents must still be signed in person, including:

  • Last will and testament
  • Divorce papers
  • Adoption papers

However, most documents that can be signed with a physical signature can also be signed electronically. Keep in mind that electronic signatures may not be accepted as valid in certain countries.

Always check if your state or location has specific laws that limit how esignatures are used in legal documents.

Is my electronic signature similar to my wet signature?

Yes, in the sense that an electronic signature is simply an electronic version of your handwritten or wet signature. It can be a digital image of your handwritten signature or a typed name.

The difference is that you create esignatures using digital tools instead of ink and paper. Often, an electronic signature is also less prone to forgery, thanks to security measures like encryption.

When can I use an electronic signature?

You can use electronic signatures to sign a document. You only need an internet-ready device, a stable internet connection, and a signature service or a platform. Some examples include signing a contract, applying for a loan, or giving consent to a medical procedure.
