How it works
Nothing to install: the sender works in the dashboard and each participant signs in the browser, on a computer or a phone.
Send
Attach the document, add the participants and choose how signing happens. Once sent, the document is frozen: what each person signs is exactly what you uploaded.
Sign
Each person receives an individual link by e-mail. To read and sign, they confirm a one-time code sent to the same address, draw or type their signature and record their acceptance. Anyone who disagrees can decline.
Track and download
In the dashboard you see who has signed and who is missing. When everyone is done, Pactaris seals the set and delivers the final package for download, ready to keep and verify.
Features
Only what already works. No promises about future features.
PDF documents up to 15 MB. The file is fixed at sending; to change anything, create a new request.
All at once or in sequence: in the chosen order, each person is invited when the previous one signs.
You decide until when the document can be signed. After the deadline the request expires and this is recorded.
Each participant has their own link, which only opens with a one-time code sent to the e-mail provided.
Draw with a finger or mouse, or type the name. The acceptance is recorded together with the exact document that was shown.
Anyone who disagrees can decline and give a reason. The refusal also goes into the event trail.
See who has signed and who is missing. Filter by status and search by title, code or participant.
Sender access requires a password and a second factor, with a code generated in an authenticator app.
Everything in the browser. The interface adapts to the screen and offers light and dark themes.
Evidence and verification
Each signature leaves organized traces. In the end, everything is gathered into a sealed, verifiable package.
A PDF with the participants, acceptances, dates and times, the IP address and browser of each access, plus the verification code.
Each event carries the hash of the previous one. Changing, removing or reordering an event no longer goes unnoticed.
Pactaris digitally signs, with Ed25519, the manifest of the files in the set. Any change to the files can be detected.
A ZIP file with everything that matters, in one place:
Anyone can check a set in the verification portal, without creating an account and without seeing the document content.
Printed in the evidence report, it leads straight to verification.
Type the request's verification code.
Upload the original, the report, the event log, the manifest or the complete ZIP.
Simple electronic signature
Pactaris offers simple electronic signature, with an evidence trail. The signer is identified by control of the e-mail address provided by the sender: the link is individual and the one-time code arrives at that same e-mail.
Frequently asked questions
It is a signature made by electronic means in which the person is identified by a simple method, here control of the e-mail, and expresses the intent to sign. Pactaris adds an evidence trail (document hash, chained events, report and seal) so the act can be checked later.
Pactaris does not promise any specific legal validity. It delivers a simple electronic signature with organized evidence; whether that level is enough depends on the type of document and on what the parties agreed. Documents that require a specific form are not covered by this service. Consult your lawyer if in doubt.
By control of the e-mail. The sender provides each participant's address, and that participant receives an individual link and a one-time code at that address. This shows that someone with access to the mailbox signed; it does not prove the person's civil identity.
No. The participant signs in the browser, with the link and the code received by e-mail. In return, Pactaris does not issue a digital certificate for the signer and is neither an advanced nor a qualified signature. If your case requires those levels, Pactaris is not the right tool.
PDF files up to 15 MB. PDFs with active content (such as JavaScript), embedded files or password protection are rejected at screening. After sending, the document is frozen: the file, the participants and the order cannot be changed. To change anything, create a new request.
From 1 to 10 participants. You choose between simultaneous order, in which everyone is invited at once, and sequential order, in which each person is invited when the previous one signs.
Anyone who disagrees can decline and give a reason. The deadline ranges from 1 to 90 days; if it ends before everyone has signed, the request expires. The sender can also cancel a request in progress. Refusal, expiry and cancellation are recorded in the event trail.
Open the link received, ask for the 6-digit code that arrives at the same e-mail, read the document and confirm the acceptance by drawing the signature or typing the name. It works in the browser on a computer or a phone, with nothing to install.
A ZIP file with the original document, the evidence report in PDF, the event log, the manifest with the digital seal, the signature images, the verification instructions and the public key. When possible, it also includes a single PDF with the original followed by the report. The single PDF is a convenience: the separate original file remains the reference.
In the verification portal, by QR Code (printed in the report), by the request code or by uploading a file from the set. The portal shows the status, the organization, the number of signatures and the seal key, without exposing the content or e-mails. Verification can also be done outside Pactaris, with common tools and the public key.
No. Pactaris's digital seal is a signature over the manifest of the files: it lets you detect any change, but it does not identify the signer and is not a personal certificate. Nor does it, by itself, prevent a file from being deleted or replaced; that is why we recommend downloading and keeping the final package.
Documents and evidence are kept in private storage, on cloud provider infrastructure that may be outside Brazil. The retention period has not been defined yet: nothing is deleted automatically, and the period will be agreed by contract with each organization. Details are in the Privacy policy.
