Form of existence: Physical seal is a physical seal, usually made of metal, rubber and other materials. It is necessary to leave seal patterns on paper or other surfaces through seal oil or inkpad. Electronic seal exists in the form of electronic file, and the authentication, signature and protection of the file are realized by digital technology and cryptographic algorithm.

Usage: the physical seal needs to be stamped by hand, and the seal pattern is transferred to paper or other surfaces. Electronic seals can be used through electronic devices, such as computers and smart phones, and can be directly authenticated and signed on electronic documents.

Security: The security of a physical seal mainly depends on the production and preservation of the seal itself. Electronic seal uses cryptography to ensure the security and integrity of documents, and the authenticity and credibility of seals can be verified by digital certificates and digital signatures.

Cross-regional recognition: physical seals are usually used in specific areas, and may need to be certified and notarized before they can be used across borders. Electronic seals can be used and recognized in different regions, which is convenient for cross-border transactions and cooperation.

Management and storage: Physical seals need physical storage to prevent seals from being lost or abused. The electronic seal can be managed and stored uniformly through the electronic document management system and the electronic signature platform, which is convenient for searching and tracing.

Generally speaking, electronic seal has higher security, convenience and cross-regional identification than physical seal, and can realize the automation of document authentication and signature process. However, when using electronic seals, it is also necessary to abide by relevant laws and regulations and choose a legally certified electronic seal service provider.
