A digital signature is a way of signing into a business agreement without the need for physical documents. It’s the legal equivalent of an ink signature and is used to ensure that both parties are held accountable for whatever is agreed upon. In a digital signature sign, each party digitally signs their agreement using their private key – a string of numbers, letters and characters unique to them. With this secure code, each party can prove they are who they say they are and have agreed to the terms of the business contract. Digital signatures offer businesses the security and convenience of not having to use pen and paper to sign agreements, so they can easily be done from anywhere in the world.
