1. Seal: instead of sparse seal, you can use official seal, private seal and other seals. Stamping a document has a similar effect, indicating the authenticity and legality of the document.
2. Handwritten signature: Handwritten signature on a document can replace sparse seal. The signature should be legible to ensure that the signer's identity can be identified.
3. Digital signature: Using digital signature technology to sign a file can ensure the integrity and authenticity of the file. Digital signature needs to be authenticated and authorized by a special digital certificate authority.
It is necessary to choose the appropriate alternative method according to the specific situation and ensure that the alternative method can meet the requirements of relevant laws and regulations. In the case that the sparse text is not printed, it is recommended to communicate with relevant institutions or departments to understand the specific alternative methods and requirements.
