2. Generally, there is only one signature and fingerprint. Of course, you can also sign and fingerprint.
Extended data:
Whether signing, stamping or fingerprinting is an effective way to prove identity, if there is no special agreement, the legal effect of the three is the same, indicating the parties' recognition of the contract.
When signing a contract, the parties can agree on the way to sign the contract, which can be only signed and sealed, or signed, sealed and thumbprinted at the same time.
In the absence of special agreement between the parties, as long as any one of the three is available, the contract is established.
However, although the efficacy is equivalent, the convenience is not the same.
For example, stamping is simple and convenient to improve efficiency. The disadvantage is that it is easy to be forged by private engraving, and sometimes it is difficult to prove that the stamped seal is the expression of my true meaning.
Because the fingerprint is unique, it can be determined whether I pressed it or not through identification, but the disadvantage is that only the fingerprint can not directly prove the identity of the parties, so it is rarely used alone.
In general, the combination of signature and fingerprint is often used. The signature should be neat and easy to identify, consistent with the name on the ID card, and no nicknames or pen names should be written.
