Digital Signature Definition UK for SignNow
Award-winning eSignature solution
What a digital signature means
A digital signature is a cryptographic way to sign an electronic record and prove who signed it and whether the document changed afterward. In practice, the signer uses a private key to create the signature, and the recipient verifies it with the matching public key. For U.S. users, that means stronger identity assurance, tamper evidence, and a clear audit trail. signNow applies this workflow to contracts, approvals, and regulated records without changing the basic signing experience.
Why it matters in U.S. transactions
It reduces paper handling, speeds approvals, and supports enforceability under ESIGN and UETA when the signer’s intent, consent, and record integrity are documented.
Common implementation challenges
Confusing a drawn eSignature with a cryptographic digital signature can weaken identity assurance and record integrity. Missing consent records can create disputes about whether the signer agreed to electronic delivery and signing. Weak authentication makes it harder to attribute the signature to a specific person in a later challenge. Incomplete audit logs can leave gaps in timestamps, device data, and document history.
Who uses it and where
Real estate
Real estate teams use it for leases, disclosures, and closing packets that need fast turnaround and clear consent.
Healthcare
Healthcare groups use it for intake forms, authorizations, and HIPAA workflows that require auditability and retention.
Typical users and personas
A NetSuite operations leader at Xerox can route the right documents to the right approvers, then keep the signing process aligned with ERP-driven workflows and internal controls. The value is less manual follow-up, clearer document status, and easier coordination across teams that already work inside connected systems. A founder at Martin Properties can send leases and approvals from the office or on mobile, while keeping a clear record of who signed, when they signed, and what was signed. That matters when speed, compliance, and customer convenience all need to stay in balance.

Core features and benefits
signNow supports secure signing workflows with clear evidence, flexible delivery, and controls that fit business and compliance needs.
Cryptographic proof
Creates a cryptographic link between the signer and the document, helping confirm identity and detect later changes.
Audit trail
Captures a time-stamped history of actions, which supports review, dispute handling, and internal controls.
Mobile signing
Works across desktop and mobile signing flows, so people can sign without changing their device habits.
Reusable templates
Supports templates for repeat documents, which reduces setup time and keeps fields consistent across sends.
Faster approvals
Helps teams manage approvals faster by removing printing, scanning, and manual routing from the process.
Compliance support
Fits regulated workflows that need clear evidence of consent, signer intent, and document integrity.
How the signing flow works
The process follows a simple sequence from document delivery to signed record storage.
Send request: The signer receives a secure request and opens the document. Verify identity: Identity checks confirm the signer before the signature is applied. Apply signature: The signature is attached and the record is sealed. Store record: The completed file and audit trail are stored for review.
Quick setup steps
Use a short setup sequence to prepare, send, and track a signing request.
Prepare file:
Upload the document and place signature fields. Set recipients:
Add recipients and set the signing order. Configure delivery:
Choose authentication and reminder options. Review status:
Send the request and monitor completion.

FAQ and troubleshooting
These answers focus on plan limits, compliance needs, and signNow features that affect real signing workflows.
signNow Business starts at $8/user/mo billed annually, and all paid plans include unlimited users. If you need bulk send, Business Premium adds it. For HIPAA workflows, a BAA is required, and retention should follow 45 CFR §164.530(j)(2).
signNow supports ESIGN and UETA-compliant workflows, but enforceability still depends on consent, intent, and attribution. Use the audit trail, signer authentication, and document history to preserve evidence that the signer acted intentionally.
If a signer cannot complete the session on mobile, signNow supports iOS and Android apps, plus desktop browsers like Chrome, Firefox, Safari, and Edge. Check device permissions, browser updates, and network access before resending.
If you need stronger identity proof, use advanced authentication options rather than email alone. signNow workflows can be configured with SMS OTP or other verification steps, which helps support higher-assurance transactions.
If you need records for regulated review, export the signed document and its audit trail together. That gives you the signing history, timestamps, and action log needed for internal review and legal support.
If your team needs a plan with bulk send or advanced controls, compare Business, Business Premium, Enterprise, and Site License. Site License adds SSO, full API access, and add-ons for HIPAA, 21 CFR Part 11, and QES.
