# Key Device

> A key device contains aggregate usage for a license key and machine code.

A key device contains aggregate usage for a license key and machine code.

Key device data is updated asynchronously, so very recent activity may not appear immediately. Machine codes are
normalized for matching: control characters are removed, leading and trailing whitespace is trimmed, values longer
than 256 characters are truncated, and the value is uppercased. Activity without a non-empty machine code is not
included in key device results.
