Devices are shared. Any enrolled User can test on any Device in the Customer's environment, because each Device receives the full synchronized user list, including the information needed to verify PINs on the Device. Results are attributed to the correct User record regardless of which Device was used. Customers typically request one Device for every 10 to 15 Users. The right number for a site also depends on how many Users start a shift at the same time and how many testing locations are needed. Each test takes about 90 seconds of User interaction in total. The final quantity is agreed during scoping and set in the Schedule. - [Getting Started](https://knowledge.sobereye.com/en/getting-started?hsLang=en) - [Running a Test](https://knowledge.sobereye.com/en/running-a-test?hsLang=en) - [Understanding Results](https://knowledge.sobereye.com/en/understanding-results?hsLang=en) - [Security and IT Requirements](https://knowledge.sobereye.com/en/security-and-it-requirements?hsLang=en) - [Users, Enrollment, and Baseline](https://knowledge.sobereye.com/en/users-enrollment-and-baseline?hsLang=en) - [Device, Software, and Connectivity](https://knowledge.sobereye.com/en/device-software-and-connectivity?hsLang=en) - [Platform Administration](https://knowledge.sobereye.com/en/platform-administration?hsLang=en) - [Safety, Privacy, and Compliance](https://knowledge.sobereye.com/en/safety-privacy-and-compliance?hsLang=en) - [Deployment and Operations](https://knowledge.sobereye.com/en/deployment-and-operations?hsLang=en) - [Troubleshooting Guide](https://knowledge.sobereye.com/en/troubleshooting-guide?hsLang=en) - Home - Products - Pricing - Blog - Company [![sobereye-dark](https://knowledge.sobereye.com/hs-fs/hubfs/sobereye-dark.png?width=300&height=73&name=sobereye-dark.png "sobereye-dark")](https://www.sobereye.com) SOBEREYE INC. 655 Oak Grove Ave. #863 Menlo Park, CA 94025 Tel: +1 408.718.0273 [mailto:contact@sobereye.com](mailto:contact@sobereye.com) Copyright © 2025, sobereye.com
