On the Pro plan, your prescriptions can be digitally signed with a qualified ICP-Brasil signature — with the same legal validity as a handwritten signature.
Set up the certificate (once)
In Settings → Digital signature, upload your A1 certificate (ICP-Brasil e-CPF, .pfx/.p12 file). It is stored encrypted and, on subsequent signatures, the app asks only for the password — which is never stored. On the same screen you can see holder and validity and remove the certificate.
A3 (token/card) and cloud certificates are not supported yet. The screen explains the certificate types and links to the official (ITI) page on where to obtain one.
Signing a prescription
On the finished prescription, tap Sign and enter the certificate password. Requirements: a CRMV registered on your profile and a configured certificate.
The signed PDF shows a "Digitally signed by … — ICP-Brasil" stamp in place of the handwritten signature.
How the pharmacy checks authenticity
- PDF: anyone can upload the file at validar.iti.gov.br — the Brazilian government confirms who signed and that nothing was tampered with.
- Paper: the signed PDF carries a QR Code and a short code that open a public AllEars.Vet validation page, even when the prescription is printed. Whoever scans it sees the signature details and can download the original signed PDF — handy for pharmacies checking a paper copy.
Signed prescriptions are immutable
Once signed, a prescription cannot be edited or deleted. To change it, use Create new version: the app creates a draft from the original (which is marked as superseded) for you to adjust and sign again. Mima follows the same rule — if you ask her to change a signed prescription, she creates the new version automatically.
