Digital vs. Electronic Signature Guide for SignNow
Award-winning eSignature solution
Key performance indicators that demonstrate SignNow's proven track record.
What digital and electronic signatures do
A digital signature uses cryptography, usually PKI and X.509 certificates, to prove identity and protect document integrity. An electronic signature is a broader legal term for any electronic symbol, process, or action that shows intent to sign. In the U.S., both can support enforceable business transactions when consent, attribution, and records are handled correctly. SignNow helps teams collect signatures, track activity, and store proof of the transaction in one place.
Why the distinction matters
The distinction affects how much identity assurance, cryptographic proof, and workflow control you need. Under ESIGN and UETA, electronic signatures remain enforceable when consent and attribution are clear, while stronger digital signatures add integrity and verification benefits for regulated or higher-risk documents.

How the signing flow works
A simple flow keeps signing fast while preserving the information needed for review, storage, and compliance.
Prepare: Create the document, add fields, and choose the signing order before sending it out. Send: Deliver the request by email, link, or app notification. Sign: The signer reviews, authenticates, and signs on web or mobile. Finalize: The platform seals the file and stores the audit trail.
What the audit trail records
An audit trail captures the evidence needed to show who signed, when they signed, and how the file stayed intact.
Signer authentication:
Timestamp capture:
Document hashing:
Tamper-evident sealing:

Record retention by governing rule
Signed records often follow the retention rule for the underlying document, not the signature method. Keep the signed copy, audit trail, and related records together.

Business types that rely on eSignature
The best fit depends on document volume, compliance needs, and how much routing control the team needs.
Solo practitioners can send NDAs, engagement letters, and intake forms quickly, while keeping document tracking simple and records organized for later review. Healthcare clinics can route consent forms and patient paperwork with audit trails, access control, and HIPAA-aligned handling of signed records. Enterprise operations teams can standardize approvals, templates, and delegated sending across departments, especially when they need consistent routing inside NetSuite, Salesforce, or other systems.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
Industry use cases and outcomes
Industry examples help show where stronger authentication, audit trails, and document controls matter most in practice.
Financial operations
A financial operations team needed faster outbound approvals and better system alignment.
- Tech Data improved speed to revenue.
- Bob Dutkowsky led internal and external service workflows.
Tech Data used airSlate SignNow to improve customer service and speed to revenue, showing how electronic signatures can remove delays in financial and operational approvals. The result was a cleaner path from document creation to completed signature, especially across repetitive workflows.
Healthcare
A fertility clinic wanted responsive API support and reliable patient forms.
- John Butler at Fertility Centers of Illinois chose SignNow.
- API support helped coordinate signing workflows.
Fertility Centers of Illinois chose SignNow for responsive support and a strong API, which helped the team handle patient-facing signature workflows more efficiently. In healthcare settings, that kind of setup can reduce turnaround time while keeping record handling aligned with compliance needs.
Common implementation pitfalls
Teams often confuse the signature method with the legal rule that governs the document, which can lead to inconsistent review and retention decisions. Signer authentication can be too weak for regulated workflows when no ID check, OTP, or audit trail is captured. A missing retention policy can leave signed records scattered across inboxes, shared drives, and local devices. People sometimes assume every document can be signed electronically, even when notarization, witness presence, or an exclusion applies.
Practical eSignature best practices
The most reliable workflows combine clear templates, measured authentication, and controlled access so the record stays usable later.
Standardize templates
Match authentication to risk
Restrict access early
Test every signing path

Supported platforms and devices
SignNow works in modern browsers and on mobile devices, so teams can send, review, and sign documents across desktop and phone environments.
Browser support Chrome, Firefox, Safari, and Edge. Desktop devices Windows and macOS desktops. Mobile access iOS and Android mobile apps.
Managed deployments often pair browser access with mobile apps, SSO, and admin controls. Regulated workflows may also require certificate handling, tighter retention policies, and device governance.
Ways to send and sign
- Use the web app for desktop preparation, batch sending, and admin review when documents need templates, routing, or detailed signer tracking.
- Use the mobile app when signers must review and sign from iOS or Android without waiting for a desktop session.
- Use kiosk mode when multiple people sign at a shared device, such as an office front desk or reception area.
- Use shareable signing links when you need fast access from email, chat, or a portal without a logged-in sender flow.

Free trial access is limited to 7 days. SignNow Business, Business Premium, and Enterprise plans are paid tiers, while all paid plans include unlimited users and audit trails.
SignNow supports HIPAA workflows when a BAA is in place and the account is configured to protect PHI, including access controls, audit trails, and retention practices.
For higher-assurance signing, use advanced signer authentication, such as 2FA or ID verification, and keep the audit trail enabled so attribution and intent are easy to prove.
The Business plan includes legally binding eSignatures, templates, mobile apps, and audit trails. Business Premium adds bulk send, kiosk mode, request payments, and quick invite links.
If a document needs higher legal assurance, use digital-signature-style controls, certificate-based authentication, and a complete record history. For ordinary U.S. contracts, ESIGN and UETA generally support standard eSignature workflows.
Wills and certain court orders are excluded from electronic signing under U.S. law. Check the document type first, since ESIGN and UETA do not override those exclusions.
