A device using the Scandit SDK version 6.x to capture data is registered as an active device once the scanner is configured and the data capture context is initialized. At that point, the SDK checks if the device already has a unique device identifier stored. If the device ID is not found, a new one is generated by the SDK, and this process is counted as a new activation.
Please be aware that activation doesn't require the camera to be turned on.
The device remains an active device for the given billing period of the subscription and if there is usage within the subsequent billing period, it will remain counted as an active device.
The device itself is identified by a unique device ID created by the Scandit SDK at first use. The device is not related to the hardware identifier (e.g. it's not the IMEI number).
