1. Stamping is more anti-counterfeiting than signature:

(The seal is unique: there are no two identical seals in the world), especially the seal that is deliberately knocked on the edge-knocking on the edge: engraving anti-counterfeiting is the most scientific method.

2. Stamping is universal (even if signed);

At present, the "seal" is the most legally effective!

4. "Seal" and "seal" are different; Stamp: The stamps we are talking about don't need anti-counterfeiting, because there are no two identical stamps. The seal is reproducible, and the only way to identify it (when it is suspicious) is to find the original seal.

A real "record" (seal, seal) does not need anti-counterfeiting.
