Verified Signatures are also sub divided into two categories. Electronic signature and Digital signature. There are some difference in both and let us check out what exactly they mean.

Electronic Signature

Electronic sign is Quick sign you add on invoices, documents and bills. In other word, if you are dealing with general paper work then Electronic signature is sufficient for you.

Digital Signature

Digital sign is more advanced, highly authenticated, and more authorized. This is widely used in a notary or third-party witness where you require a high level of security. When you add a digital signature on your document then that document is encrypted and locked. For a digital signature, you have to go for the third-party tool.

The most common question now a days is do the electronic signature are legal. The answer is YES! If you create an ID and set a verified digital signature then this is legal and only you have authentication to make changes to that document. It is widely used by firms for online contracts.
