The device uses this property to report its operational status.
Online is the status the manufacturer populates in this property before shipping, and is the result of the device going through processes that configure its security subsystems and features. In this state, the device is fully functional and can perform transactions.
Offline means the device is no longer fully functional and can no longer perform transactions. The device automatically transitions to this state if it detects a problem with security or any of the subsystems it checks. For example, trying to open the device triggers a tamper response, which causes the device to change its operational status to Offline. To retrieve more information about the cause of an Offline status, the host can retrieve Property 2.3.1.2.1.2 Offline Status Detail.
