Each GS-King X is shipped with a QR code. This QR code is generated according to the key burned by the machine. The QR code produced by each machine is different. The user downloads and installs the mobile terminal software provided by us. After the software is registered, you can scan the QR code attached to the machine to add the device, and then you can access the internal storage space of the machine through the software to implement functions such as uploading, downloading, and sharing.
