Enterprise POS installs on Android, iOS and Windows, with a silent install path for large rollouts.
Use the documented replace terminal procedure rather than provisioning a new device from scratch, so the replacement inherits the original terminal identity, drawer assignment and reporting continuity.
Remove the terminal properly when a device is retired, so it stops appearing in drawer lists and reporting.
Install POS, covering system requirements, Android, iOS, Windows, silent install, download data to terminals, replace terminal and remove terminal.
