-> Note: If your device is an arm based architecture, please use get device uuid API to generate the uuid: 
-> ```python
-> # sample code in python
-> print(BarcodeReader.get_device_uuid(1))
-> ```
-
-> Note: If you want multiple users in operating system to use the license, you will need to move the .Dynamsoft folder to a path where all the users can access. Let us say `/Home/shared/.Dynamsoft`.
-> For all the programs in the devices, you will need to set the license cache path to `/Home/shared` before initialize the license
-> ```python
-> # set license cache path before initialize the license
-> BarcodeReader.set_license_cache_path("/Home/shared")
-> ```
