Signatures Rooted in Physical Reality.
Stop relying on software-only e-signatures that can be easily disputed. Aeion E-Signatures bridges the gap between the web and the physical world. Through the Aeion Bridge desktop companion, integrate directly with Wacom USB signature pads, scan government IDs via barcode readers, and capture witness photos during high-stakes signing ceremonies—all backed by an immutable, ESIGN-compliant audit trail.
The Ultimate Signing Ceremony
Native USB Pad Integration
Software-only signatures are just typed text. Aeion E-Sign connects directly to Wacom STU and Topaz USB signature pads via WebHID, capturing thousands of biometric pressure points to generate wet-ink-quality vector (SVG) and raster (PNG) signatures at the point of service.
Instant Identity Verification
Don't just trust an email address. Plug in a standard HID barcode scanner. When a signer presents a US Driver's License, the system instantly parses the AAMVA PDF417 barcode to cryptographically extract and verify their Name, Address, and Date of Birth into the audit trail.
Witness & Camera Capture
High-stakes legal documents require witnesses. The platform seamlessly hooks into document cameras and webcams to capture high-resolution photos of physical IDs, signed paper addendums, and even the physical face of the witness at the exact moment of execution.
Immutable Legal Audit Trails
Every signature event is cryptographically linked into a tamper-evident SHA-256 audit chain, so any insertion, deletion, reordering, or edit anywhere in a document's history is detectable. The system records the precise timestamp, the IP address, device fingerprints, and the raw biometric stroke count. On completion, the final PDF is sealed with a SHA-256 content hash — the Certificate of Completion embeds every signer, timestamp, and the audit chain's integrity proof, and re-verifying the stored PDF at any time detects any post-seal change. This record-integrity model satisfies the ESIGN Act / UETA integrity requirements.
Multi-Party Document Routing
Automate your document lifecycle. Route documents to multiple signers using parallel (everyone at once) or sequential (Step 1 → Step 2) workflows — each signer is notified automatically the moment it's their turn, and still-pending signers get automatic reminders on a configurable cadence.
Progressive Enhancement
No hardware? No problem. The platform gracefully degrades to a standard browser-based signing experience (typed or mouse-drawn signatures) for remote clients, while instantly unlocking hardware capabilities the moment a USB signature pad is detected via the Aeion Bridge.
Bridging Software and Hardware
Zero-Config Drivers
Historically, making a web app talk to a Wacom pad required awful Java applets or ActiveX controls. The Aeion Bridge handles hardware I/O cleanly, passing signature and scan data to Aeion OS over a secure, local connection.
Image Enhancement AI
Document camera captures are rarely perfect. The system intercepts the raw camera blob and runs it through an integrated AI enhancement pass—automatically adjusting contrast, deskewing the angle, and cropping the margins before appending it to the legal packet.
Legally Binding, Wherever Your Signers Are
International Compliance
Compliant with ESIGN Act (US), UETA (US states), eIDAS (EU), UK Electronic Communications Act, Singapore ETA, and India IT Act — with per-jurisdiction identity-proofing flows so a "standard" vs. "advanced" electronic signature requirement is handled automatically, not left to a legal team's guesswork.
Tiered Identity Verification
Email verification for low-stakes agreements, SMS one-time codes for medium-stakes, and full government-ID scan + biometric signature capture for the high-stakes signatures — real estate, financial, healthcare — where a disputed signature has real consequences.
Frequently Asked Questions
DocuSign is a standalone e-signature platform with per-envelope fees. Aeion eSign is built into the OS — contract documents from Legal flow directly into eSign without copy-paste; signatures bind back to the originating contract; renewal reminders fire from the same data; zero per-envelope fee beyond standard platform usage.
Yes — compliant with ESIGN Act (US), UETA (US states), eIDAS (EU), UK Electronic Communications Act, Singapore ETA, India IT Act. Per-jurisdiction signature requirements (standard vs. advanced electronic signature) are supported with appropriate identity-proofing flows.
Tiered IDV — email verification (low stakes), SMS one-time code (medium), government-ID scan + biometric signature capture (high, for real-estate / financial / healthcare).
Yes — form fields (text, date, checkbox, dropdown, signature), conditional logic ("if 'corporate' selected, show signing-authority field"), attachments (proof of ID, certificate of insurance), and multi-party serial / parallel signing workflows.
Stored in the tenant's S3 / R2 / Azure storage (your bucket, your data sovereignty). The sealed Certificate of Completion carries a SHA-256 content seal, and every signature event is linked into a tamper-evident SHA-256 hash chain (date, IP, user agent of each signer).
