Contract & Agreement SigningScanOrbit Pro

Sign PDF Documents Privately on Your Android Phone

Q: Are signatures created in ScanOrbit legally binding?

Yes. Electronic signatures generated and embedded into PDF documents are widely accepted for standard business agreements, contracts, and lease documents under e-signature frameworks like the ESIGN Act and eIDAS.

Q: Can I scan my real handwritten signature from a piece of paper?

Yes! ScanOrbit includes a specialized signature scanner (`sig-scan`) that photographs a pen-and-paper signature, crops the ink, removes the paper background, and saves it as a transparent digital stamp.

Q: Does ScanOrbit put a trial watermark on signed documents?

Never. All documents exported from ScanOrbit are 100% clean, professional, and free of any watermarks or advertising tags.

Add legally binding electronic signatures to PDF contracts, lease agreements, invoices, and consent forms. Draw your signature on screen, import a handwritten signature from paper, and place it precisely where needed.
