Legal analysis: it is best to print it on the name to prevent it from being used by others. This is a kind of self-protection. As long as the parties personally sign or seal, it is valid. The law does not stipulate that fingerprints must be used. This is just a traditional habit. If the parties conclude a contract in the form of a contract, the contract shall be established when both parties sign or seal it.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
