What is digital signature used for

TL;DR

Digital signatures let people sign, fill, and send documents electronically with legal validity under U.S. law. signNow supports common workflows — upload a file, add fields, send for signature, track status, and securely store completed records. It includes audit trails, encryption, HIPAA support with a BAA, mobile signing, and integrations with CRMs and storage to speed approvals and reduce paper handling.

What digital signatures are

A digital signature is a secure electronic way to show that someone approves a document, similar to signing a paper form but done online. It confirms who signed and when, and prevents later changes without detection. In practical use, a user uploads a contract or form, adds signature and data fields, sends it for signature, and receives a completed, tamper-evident PDF. Platforms like signNow combine simple fill-and-sign steps with audit trails, encryption, mobile support, and integrations so teams can complete and store agreements faster and more securely than paper workflows.

Why electronic signing matters legally

Electronic signatures are legally recognized in the U.S. under the ESIGN Act and UETA, and they reduce processing time, lower costs, and improve recordkeeping. Use signNow when closing remote sales contracts or collecting employee onboarding signatures at scale; it supports compliance, audit trails, and secure storage for regulated industries.

Common eSignature challenges

• Confusion over signer identity when authentication is weak, leading to potential disputes and delays in contract acceptance.
• Document version control issues when multiple parties edit PDFs offline, increasing risk of invalid or inconsistent final agreements.
• Regulatory requirements for sensitive data that demand BAAs, encryption, and strict access controls for health or financial records.
• Integration gaps between eSignature tools and core systems like CRM or ERP, causing manual work and slowing approval cycles.

Who uses digital signatures

Businesses of all sizes use eSignatures to speed approvals, cut paper costs, and improve auditability across departments.

• Real estate agents use online signing for leases, purchase agreements, and disclosures to close deals remotely.
• Healthcare practices collect patient consent and intake forms electronically with HIPAA-protected workflows and BAAs.
• Finance and legal teams execute contracts, tax forms, and lender documents while preserving audit trails and timestamps.

Public and private organizations adopt eSignatures for efficiency, compliance, and easier recordkeeping across mobile and desktop platforms.

Core eSignature capabilities

Key features support common document types and signing patterns, helping teams replace paper processes across departments and devices.

Templates

Reusable templates let teams predefine field placement, signer roles, and conditional logic so recurring forms are sent consistently and completed faster.

Bulk Send

Bulk send distributes the same document to many recipients at once, automating individualized fields and tracking returns to reduce manual sending overhead.

Mobile Signing

FAQs About eSignature problems

This section addresses common issues users encounter with eSignature workflows and practical steps to resolve them when using signNow.

• Why a signer cannot access a document
  Confirm the recipient email is correct, check spam folders, and verify any access code or authentication step required. If email delivery fails, resend and confirm mailbox settings; for persistent delivery issues contact your IT team to allow signNow domains.
• How to fix incorrect field placement
  Before sending, open the editor, move or resize fields as needed, and save as a template. If a document was sent with errors, void and resend a corrected copy to ensure the audit trail reflects the new, authoritative version.
• What to do when signatures are missing
  Check the document status in Dashboard to see signer actions. If a signer viewed but did not sign, send a polite reminder or enable automatic reminders. For completed disputes, export the audit trail for review.
• Resolving authentication failures
  If a signer fails authentication, verify the method configured (email code, SMS), confirm contact details, and provide a secondary verification route. For advanced auth, coordinate with IT or signNow support to validate identity options.
• Troubleshooting API integration errors
  Validate API keys, webhook endpoints, and scopes. Check request payloads for required fields and review signNow API responses for error codes. Use staging environments before production changes.
• Recovering a lost signed document
  Search account folders, check connected cloud storage, and request a new copy from signNow account history. Ensure retention policies prevent premature deletion for future recovery needs.
