About DigSig Authenticator
The DigSig Authenticator is your one stop shop for verifying DigSigs and getting a digital version of your document displayed right on your phone. But what is a DigSig? A DigSig is a code applied to a document in the form of barcode or NFC to authenticate it and ensure it hasn't been tampered with. It functions as a digital "stamp" and is utilised with a specific blueprint to validate the document's original condition, certifying it has remained unaltered since it was stamped.
