V4S Kiosk is an Android app that you can use to check in, check out and sign up new volunteers, all on registered public devices (tablets, usually) at volunteer locations that everyone will use. Volunteers can search for specific jobs and shifts that they have signed up for and check-in / check-out to track times for those jobs/shifts. All data from these devices is synced to your Volunteers for Salesforce org in real time. Your volunteer coordinators can track volunteer attendance and hours in real time on their V4S Mobile dashboards in Salesforce. A valid Salesforce subscription is needed to be able to use V4S Kiosk.
