How to sign a document

The complete process for signing a document in ArcaSign, either handwritten or with a BCCR certified digital signature.

Receiving the signature request

When someone sends you a document to sign, you will receive an email from ArcaSign with the subject “You have a document pending signature”. The email includes a unique, secure link.

Accessing the document

Click View and sign document. You do not need an ArcaSign account to sign — the link takes you directly to the document.

Reviewing the document

Read the full document before signing. You can download a preview copy as a PDF to review it more comfortably.

Choose how to sign

ArcaSign offers you two ways to sign the same document:

  • Handwritten signature: draw your signature directly in the browser. No certificate and nothing to install.
  • BCCR certified digital signature: use your card and the desktop signer app. It has the same legal validity as a handwritten signature before a notary (Costa Rica, Law 8454).

Sign by hand

  1. Choose Sign by hand.
  2. Draw your signature in the box with your mouse or finger.
  3. Confirm the signature.

Sign with a BCCR certified digital signature

  1. The first time, install ArcaSign’s desktop signer app when the system prompts you.
  2. Connect your signing device (card or USB).
  3. Click Sign with digital signature.
  4. The signer app will detect your certificate.
  5. Enter your PIN when the system requests it.
  6. Confirm the signature.

Signature completed

Once signed, you will receive by email a copy of the document with your signature embedded. The sender is also notified immediately.

Common problems

  • The certificate is not detected: make sure the desktop signer app is installed and the card reader is connected before signing.
  • PIN blocked: contact the BCCR directly to unblock your certificate.
  • Link expired: ask the sender to resend the document.
