Various embodiments of a machine-to-machine visual code generation and recognition method and a corresponding system are disclosed. In one embodiment, a first machine gathers real-time hardware setting information of the first machine, and subsequently generates a first QR code that embeds hardware setting information of the first machine. The first QR code is displayed to a display panel connected to the first machine, and a second machine with a camera captures the first QR code, and deciphers the first QR code to determine communication compatibility between the first machine and the second machine. Then, the second machine formulates a response that incorporates its own real-time hardware setting information, and generates a second QR code that embeds the second machine's response to the first machine. Subsequently, the first machine scans the second QR code from the second machine's display panel, and registers the second machine's hardware setting information.
