What Are Digital Signatures?

A digital signature is an electronic way to authenticate a document. It allows the recipient to verify that the document came from the right sender and that it has not been altered in transit.

Digital signatures are used for various purposes, including signing financial documents, and legal contracts. In some countries, they are as legally binding as a handwritten signature.

With a digital signature, there’s no need to print out documents or have them couriered to you for signing. Also, it’s more difficult to forge a digital signature than a handwritten one.

When can you use a digital signature? Imagine you’re buying a house. With digital signatures, all parties can sign the necessary paperwork meeting in person. This can speed up the closing process and get you into your new home faster.

Are Digital Signatures Legally Valid?

Most countries accept digital or electronic signatures, provided you follow specific conditions. Always check your local laws to ensure your esignature is accepted as valid.

If you are in the United States, take a closer look at the E-Sign Act, also known as the Electronic Signatures in Global and National Commerce Act. This federal law was enacted in 2000. It establishes the legal validity of electronic signatures and records, making them as enforceable as paper documents with handwritten signatures.

How Do Digital Signatures Work?

You can create a digital signature using specialized software on your laptop, desktop, or mobile device. Here’s how to do it:

  1. Type your whole name or initials. Then, choose a font style that is similar to your handwriting.
  2. Draw your signature on a trackpad or mouse pad with your fingertip. Alternatively, you can also use a digital pen or stylus.
  3. Capture and upload an image of your handwritten signature. Use a white background for better quality.

Most esignature software or services use encryption and other security measures to protect your files. For example, Fill provides the option to activate both signer identity verification and two-factor authentication.

Signatories have to submit a valid ID to prove their identity. Once confirmed, that’s the only time a signer can electronically authenticate a document. These security measures ensure that your signature can’t be forged.
