Download the Signer

The desktop app that reads your BCCR digital signature card and signs your documents on your own computer. Choose your operating system.

When installing

The installer is not code-signed yet, so Windows (SmartScreen) or macOS (Gatekeeper) may warn about an “unidentified developer”. This is expected: on Windows click “More info → Run anyway”; on macOS, right-click the app → “Open”.

After installing

Open the app, sign in with your ArcaSign account and insert your card. You need the BCCR drivers (Soporte Firma Digital) installed.

Java is bundled — nothing else to install.
