Proof

Required Hardware and Software to Complete Transactions on Proof

To complete transactions on Proof, users need a modern computer, smartphone, or tablet with an autofocus camera supporting h264, functional audio devices, Adobe Acrobat Reader, a stable broadband internet connection with at least 5 Mbps upload and 20 Mbps download speeds, and must use a supported web browser (Chrome, Firefox, Edge, Safari) or the Notarize mobile app—except for real estate closings, which require a web browser and are not supported on the mobile app.

The short answer: To complete a transaction on Proof, you need a stable internet connection and a compatible device with a camera and microphone. Most modern computers, smartphones, and tablets will work fine.

Important for Real Estate: Real estate transactions and closings can be completed on a mobile device via a web browser, but they are not supported on the Notarize mobile app.

1. Hardware and Software

Using hardware or software below these specifications may cause technical issues during your session.

  • Device: A computer, smartphone, or tablet running a modern operating system — no more than three versions older than the current release.
  • Camera and Audio: An autofocus camera supporting the h264 codec, and functional speakers and microphone (or headphones).
  • PDF Viewer: Adobe Acrobat Reader is recommended for viewing documents.

2. How to Access Proof

You can join your session through a web browser or the mobile app:

  • Web Browser (recommended): Supported browsers are the current releases of Chrome, Firefox, and Edge (within the last 10 versions) and Safari (within the last 3 versions).
  • Mobile App: You can use the Notarize app for iOS or Android, except for real estate closings.

3. Internet Connection

A reliable broadband connection is required to maintain a live, high-quality audio-video stream. For the best experience, a hardwired connection or a strong Wi-Fi signal is recommended.

Specification | Optimal

  • Ping: Less than 30ms
  • Upload Speed: 5 Mbps
  • Download Speed: 20 Mbps

Summary Checklist

  • Use a compatible device with a working camera, microphone, and speakers.
  • Use a supported browser — Chrome, Firefox, Edge, or Safari — or the Notarize mobile app (non-real estate only).
  • Ensure a stable broadband connection with at least 5 Mbps upload and 20 Mbps download.
  • Real estate closings must be completed via a web browser, not the Notarize mobile app.
