If someone else takes a copy of your ID card to sign a contract that you didn't sign yourself, you don't need to bear the contract responsibility, and you can disclose that the contract is invalid to the other party. However, if the relationship between the actual signatory and you is enough to convince the other party that you agree, then the contract is valid. When copying a copy of your ID card, you'd better sign it to explain the purpose, and you can't use it for other purposes.
