COMPARISON
E-signature vs physical seal control:
what is the difference?
E-signature and physical seal control solve different problems: one works on electronic files, the other on paper originals and physical seals.
THE SHORT ANSWER
Not a replacement; a boundary decision
E-signature and physical seal control solve different problems: one works on electronic files, the other on paper originals and physical seals.
- Start with the document format
- Then check the sealing location and custody
- Then decide whether comparison, records and integration are needed

| E-signature | Physical seal control | |
|---|---|---|
| Object | Electronic files and online contracts | Paper contracts, letters and certificates |
| Core capability | Digital certificates, electronic signatures and online workflow | Seal isolation, automatic sealing, document comparison and records |
| Typical use | Standard online business and remote signing | Bank outlets, credit contracts, multi-entity groups and paper originals |
| Risk focus | Identity, key management and electronic evidence | Seal isolation, page replacement, unauthorized sealing and audit |
| Relationship | Can run in parallel | Does not replace e-signature; handles the paper last mile |
When to choose which
- If the file can be fully electronic and the counterparty accepts e-signature, evaluate e-signature first.
- If regulation, customer or business process requires paper originals and a physical seal, evaluate physical seal control.
- Large institutions often need both, routed by document type and business rules.
Can e-signature completely replace physical seals?
Not universally. E-signature fits electronic files and online workflows; paper originals, physical seals and certain regulatory scenarios still need physical seal control.
Do we still need a seal robot after e-signature?
If you still seal paper contracts, letters or certificates, you need a way to control the physical seal. The two systems can coexist.
