Legal analysis: if a written contract is concluded, the contract shall be established when both parties sign or seal it. As long as we abide by the mandatory provisions of our laws, it is effective to conclude a contract by scanning, that is to say, we can sign a contract by electronic scanning. However, in order to avoid disputes in the subsequent contract signing, it is best for both parties to sign the contract face to face in the presence of both parties.
