It often happens that some important and urgent documents need to be signed by the boss in daily office. At this point, if the boss is in the company, print out the document and give it to the boss to sign his name.

By using the signature line in Word, documents such as contracts or other agreements can be signed paperless, such as inserting a handwritten signature into the contract and affixing an electronic seal to the document, which helps to ensure that the identity of the signer is consistent with the statement, and the content has not been changed or tampered after the signature is confirmed, and helps to prove the effectiveness of the signed content to all parties.
