IT点呼キーパーv2 スマホ版 is a utility and tools application available on the Android platform. Developed by テレニシ株式会社, this app requires a contract with IT点呼キーパー in order to use it.

This app allows users to conduct telephone roll calls with drivers, simulating a video call experience. It not only enables alcohol testing but also allows for checking the drivers' health condition by providing a visual of their faces, thus ensuring safer operations. Additionally, the app automatically records the driver's location using GPS information.

In areas with poor mobile network coverage where video calls are not possible, the app allows for offline alcohol testing.
