The release said that the app uses VPN technology to temporarily "brick" or restrict smartphone usage by redirecting the phone's web traffic through a restricted, encrypted server. It will also prevent students from texting and accessing "distracting" apps. A "DoorTag" will be located at the entrance of each classroom, on which students will tap their phones. The device will log the student's attendance and restrict selected phone applications. Students will still be able to make and receive phone calls and use approved apps, such as Google Classroom.
