Use Digital Signature With SignNow
Award-winning eSignature solution
What a digital signature does
A digital signature is an electronic signature that uses cryptographic methods to confirm who signed a document and to detect later changes. In practice, the signer’s identity is linked to the document through public key infrastructure, a hash, and a private key. When the document is signed, the system creates a tamper-evident record that can be verified later. In the U.S., this supports secure online agreements, faster approvals, and clearer evidence of intent across business workflows.
Why digital signatures matter
Digital signatures reduce paper handling, speed approvals, and create stronger evidence of intent. Under ESIGN and UETA, they can be legally enforceable when the signer’s identity, consent, and record integrity are preserved.
Frequent digital signature issues
Signer identity can be disputed if authentication is too weak for the transaction risk. Document changes after signing can break trust if tamper-evident controls are missing. Poor consent capture can weaken enforceability under ESIGN and UETA. Missing audit details can make it harder to defend the record in a dispute.

Core features for digital signing
Digital signatures work best when the workflow is secure, traceable, and easy for signers to complete across devices.
Tamper evidence
Create signed records with cryptographic integrity so later edits are detectable and the completed file remains defensible.
Audit trail
Capture signer identity, timestamps, and document history in one record for clearer audit support.
Mobile access
Use mobile signing to complete approvals on phones, tablets, or desktops without changing the workflow.
Signing order
Route documents in order so each signer receives the file at the right stage.
Templates
Reuse approved forms and clauses to reduce repetitive setup and keep document versions consistent.
Faster turnaround
Collect signatures faster with simple request flows that reduce manual follow-up and paper handling.
How digital signatures work
The signing process follows a short sequence that links identity, document integrity, and record retention.
Open document: The signer opens the document and reviews the request. Verify signer: Identity is verified with the chosen authentication method. Sign document: The signature is applied and linked to the record. Save record: The system stores the signed file and audit history.
Quick steps to use digital signatures
A simple setup keeps the signing process clear for both senders and recipients.

Recommended workflow settings
Use stronger identity checks for sensitive records, preserve a complete audit trail, and keep retention aligned with the governing record rule.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP for higher-risk transactions |
| Signature type | Cryptographic digital signature |
| Audit trail | Full time-stamped event log |

Real-world use cases
These examples show how signNow fits document-heavy workflows where identity, speed, and record integrity all matter.
Enterprise operations
A Xerox operations leader needed flexible routing across systems and document formats.
- NetSuite integration guided the right signatures to the right documents.
- The workflow reduced format friction across teams.
The result was better control over signature routing and fewer manual handoffs across connected business systems.
Real estate
A real estate founder needed online execution for property documents with compliance and security.
- Mobile signing supported work away from the office.
- Offline access helped keep document flow moving.
The workflow supported faster document execution while keeping records organized for property transactions and related approvals.
Best practices for digital signatures
A controlled workflow helps preserve identity, integrity, and record quality across routine and regulated signing tasks.

FAQ and troubleshooting
These answers focus on record integrity, compliance, and plan limits that affect digital signature workflows in the U.S.
If a HIPAA workflow needs a BAA, use a signNow plan and agreement that support HIPAA handling. HIPAA requires a BAA when a vendor handles PHI, and signed records should keep audit history and access controls intact.
If a signer says the document changed after signing, check the audit trail and file hash. signNow records time-stamped events, and a tamper-evident record helps show whether the document was altered after signature.
If a court or regulator asks for proof, export the audit trail and signed PDF. ESIGN and UETA support electronic signatures, but the record should show signer identity, intent, timestamps, and document history.
If a team needs bulk sending, use a plan that includes bulk send, such as Business Premium. The Business plan covers legally binding eSignatures, templates, and audit trails, but bulk send is listed with higher tiers.
If a healthcare or life sciences workflow needs stronger controls, use 21 CFR Part 11 features such as unique user IDs, time-stamped audit trails, and documented validation. signNow’s compliance profile should be matched to the regulated process.
If a mobile signer cannot complete the process, confirm the device and app path. signNow supports iOS and Android signing, and mobile-created eSignatures remain valid when intent, attribution, and consent are documented.
