Legal analysis
Of course, the signature is legally binding, and of course, handwriting identification also needs circumstantial evidence, such as his other handwritten evidence. Foreign signatures are very effective, and signatures are not as important as domestic ones. As for fingerprints, it is not necessarily my true meaning, such as pressing his hand, so any signature method is flawed and cannot be perfect. Signature recognition depends on writing habits, not whether it is exactly the same. Even if the writing is different, the habits are usually the same. In actual civil activities, there are usually other evidences to prove it. Important civil activities are generally confirmed by seals, notarization and other means. In criminal or some civil activities, fingerprints are often added to prove that they are the same as signatures. In short, it is not that the signature has legal effect, but that the signature is a kind of evidence and voucher to prove the expression of intention. Generally speaking, this will do. If it is not enough, there are many other means. Signature is habitual, and a new writing habit will remain stable for a period of time. Write a different name every time. That's because you're a layman. Every time you write, you are exposed to exquisiteness. The signature is legally binding. Don't do anything illegal.
