Legal analysis: the signed labor contract is valid without fingerprints. The conclusion of a labor contract is not based on fingerprints and does not affect the effectiveness of the contract.

Legal basis: Article 17 of People's Republic of China (PRC) Labor Law shall follow the principles of equality, voluntariness and consensus through consultation, and shall not violate the provisions of laws and administrative regulations. After a labor contract is concluded in accordance with the law, it is legally binding, and the parties must fulfill their obligations under the labor contract.
