Kisok can be new (company tax write off) or used such as this: ​Restored Apple iPad ​​​

The Rippling Time Clock app is available on iOS and Android tablets only. Surface tablets, or any devices utilizing the Microsoft App Store, do not support Rippling's Time Clock app.

Rippling recommends using the most recent operating system versions on tablets. When purchasing a tablet for the Kiosk app, keep in mind that although these are the minimum requirements at this moment, the minimum required software is subject to updates. The App Store and the Google Play Store will update their operating systems and stop supporting older versions over time. For that reason, Rippling recommends buying a tablet created within the last 4-5 years, to avoid running into a situation where your tablet's operating system is no longer supported. 

Below are the minimum versions of each tablet operating system suggested.

iPad: (12.0 and up)
For the most recent requirements, visit the app shop directly.
Android: (8.0 and up)
