There are two signature types in AllEars.Vet, with different legal weight. When you sign a prescription or document, you choose which to use.
- Digital signature (ICP-Brasil): a qualified electronic signature (MP 2.200-2/2001) — the same legal validity as a handwritten signature, verifiable and tamper-evident. Requires an A1 digital certificate. Available on the Pro plan.
- Handwritten signature: a photo of your signature, converted to high contrast and stamped onto the document. Equivalent to a printed, hand-signed document — not a qualified signature and with no ICP-Brasil verification. Available on all plans (a CRMV is enough). It cannot be used on special-control or compounded prescriptions, which require the digital signature — on those types the method shows disabled in the signing dialog with the note "Unavailable for this prescription type".
Set up the certificate (once)
In Settings → Signatures, 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.
Set up the handwritten signature
On the same Settings → Signatures screen, under Handwritten signature, upload a photo of your signature: sign with a dark pen on white paper, with good lighting and no shadows, framing only the signature. The app removes the background automatically and shows a high-contrast preview. A CRMV is all you need.
Signing a prescription or document
Tap Sign — the action lives in the ⋯ (more actions) menu and, on mobile, also in the prescription's or document's bottom panel. The ⋯ menu offers Sign while you are editing too: the app saves first and goes straight to signing. Choose the method: Digital signature (enter the certificate password) or Handwritten signature (no password) — in both cases the app opens the PDF and you drag the signature/stamp to the exact spot, choosing position and size. Common requirement: a CRMV registered on your profile.
When signing with the ICP-Brasil certificate on documents, simple prescriptions and uploaded PDFs, the app opens the PDF and you drag the signature stamp (text + QR) to the spot you want, choosing its position and size, before confirming. Magistral and special-control prescriptions keep the stamp in a fixed position. The stamp is only visual — legal validity comes from the signature embedded in the file, always verifiable.
The certificate-signed PDF shows a "Digitally signed by … — ICP-Brasil" stamp; the image-signed one shows your signature with your name, the signing date and the note "Scanned handwritten signature — no ICP-Brasil certification".
How the pharmacy checks authenticity (digital signature only)
- 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. The old version's public validation page (from the QR) then shows a "superseded prescription" notice — anyone scanning an outdated paper copy finds out. Mima follows the same rule — if you ask her to change a signed prescription, she creates the new version automatically.
