blue·auth
Read full descriptionHide full description
Sign contracts and documents from your phone, with legal standing recognised across the European Union. When somebody sends you a document to sign, it turns up here. You get a notification, open it, read the whole thing and sign in the right place. No more printing, signing by hand, scanning and sending it back. QUALIFIED SIGNATURES Sign with the Portuguese Chave Móvel Digital and you get a qualified electronic signature, the highest level European law recognises. It carries the same weight as a signature witnessed in person, and is accepted by courts, banks, notaries and public services. If you would rather not, you can always sign the ordinary way, by drawing your signature on the screen. IDENTITY CHECKS When the sender asks for stronger proof, the app captures a photo of your identity document and runs a short video check that tells a real person from a photograph. All of it is stored alongside the document, as evidence. ALWAYS KNOW WHERE THINGS STAND See what is waiting for you, what you have signed and what is finished. On a document with several people, you can see who has signed and who is still holding it up. THE ORIGINAL IS ALWAYS ONE STEP AWAY Every signed document carries a code that takes anyone back to the original online, with the full record of who signed, when and from where. Print it or share it freely: the paper never loses its link to the original. PRIVATE BY DEFAULT The app opens with Face ID or Touch ID. Your documents are yours, and blue·auth was built from the ground up to prove a document is genuine without having to expose it. PART OF blueauth.co The app is one piece of a larger platform, with timestamping, document anonymisation, certificates, forensic evidence custody and tools for teams. What you sign here shows up there, and the other way round. A blue·auth account is required. You can create one at blueauth.co.
