Handprint is a signature seal, which is engraved according to the owner's own handwriting. I hold and use my signature, which shows the true meaning of the parties and has the same effect as my signature. If you can't judge that the signature is for your own use, the signer himself can't confirm it because he has lost his will, and he can't judge his clear authorization and expression of will from other evidence. It is not enough to represent the true meaning of the signer only by signing, and the signed document has no signature effect.

With the development of social economy, transactions between enterprises become more and more frequent. In order to meet the needs of transactions, more and more business leaders use handwritten signatures instead of autographs. Electronic signature has gradually begun. Because modern seals are carved by computer, the probability of being forged has increased accordingly. Individual seals have become a mere formality, so handwritten signatures are often combined. With the improvement of modern fingerprint analysis ability, some important contracts should be stamped with handprints in addition to signatures and seals, including signatures, seals and handprints. In some cases, even if there is only a personal signature and no signature, it will not be invalid because it is not my signature. In the asset appraisal procedure, the appraisal report signed by the appraiser also has legal effect.
