Use facial recognition, liveness detection, document OCR, and Device Scan to sign your documents with maximum protection and authenticity.
Gain more security in your electronic signature
Many companies need stronger protection in document management and signature processes, even at high volume. Integrate via API and safeguard your business.
Facial Recognition
Increase the accuracy of your signing process through facial validation of signatories. Our anti-spoofing technology helps detect masks and tampered photos, while facematch compares the signer’s selfie with our database of over 120 million faces, verifying that the person is truly who they claim to be, all in just seconds.
Device analysis
Geolocation, installed apps, and much more, we scan the signer’s device to understand the context of the signature and detect any signs of fraud, from device tampering to previous use by fraudsters.
An additional layer of security, in a solution already integrated with WhatsApp and SMS.
Document validation
Speed up the extraction, reading, and verification of documents such as driver’s licenses (CNH) and ID cards (RG) in seconds with OCR technology.
Direct or API management
Manage all documents, signed or pending signature, directly from the dashboard, with options to resend signature links and download documents. Alternatively, integrate seamlessly through our API, connecting directly to your preferred system.
01
Sign with end-to-end security
01
Upload
The company uploads the document for signature (or a batch of documents via API) and sends the link through SMS, email, or WhatsApp, all fully integrated.
02
Validation
We capture an image of the user’s document and instantly verify it. Then, a selfie confirms identity and liveness, ensuring the signer is who they claim to be.
03
Signature
The user receives a confirmation token and signs the document, adding an extra layer of security to a process that already carries full legal validity.
04
Confirmation
All parties receive a signature confirmation. A digital dossier is generated, and the company can manage all documents directly on the platform or through the API.
