Electronic signatures are a way to sign documents, like a contract or a form, without actually having to write your name. When you use an electronic signature, you're usually typing your name or drawing a picture of your signature on the computer. Electronic signatures help you sign documents quickly, without having to print them out, and make sure that your signature is protected from being changed.
The law says that when you sign something electronically, it has the same power and weight as if you wrote your signature on paper. So if you use an electronic signature for something important, like a contract, both you and the other person will be legally protected in the same way as if you wrote your signature by hand.
