Designed for construction sites, the TimePilot Extreme is a portable and weatherproof time and attendance system. Workers can clock in and out onsite, and when the project is finished, the clock can be removed easily and taken to the next site. Workers are given a key-sized device, called an iButton, to clock in and out by tapping the clock. The waterproof iButton can be carried on a keychain, can be reassigned to another employee, and lasts at least 10 years. TimePilot Corp.
