When a customer uses well designed online activation it looks nearly identical to “serial-only” licensing. The most popular variation of hardware-locked licensing is “online activation.” Most people have encountered this type of licensing when they purchase a copy of Microsoft Windows or Microsoft Office. Hardware-locked licensing is known by many names (like node locked, etc.) and there are many variations. This means increased revenue by preventing casual piracy.

Hardware ID of the fingerprint sensor should be something like "ACPI\ELAN7005" based on the driver files I installed the driver for the fingerprint sensor from the official Asus UX550GD product page under the Windows 11 category.

I have been using an Asus ZenBook Pro UX550GD laptop with Windows 10 for a few years now, the fingerprint sensor was working flawlessly.
