The invention discloses an IT asset management unit, an IT asset management system and an IT asset management method. IT asset information is stored through the IT asset management unit, therefore, input errors cannot occur, the IT asset information is not prone to damage, stain-resistant performance is strong, the IT asset information can be stored for a long time, and viewing is convenient. The IT asset information is transmitted through radio frequency signals, and therefore the distance range for reading data is effectively increased. The IT asset management system is used for managing IT assets, therefore, the capacity to manage the IT assets can be effectively improved, and the conditions of the IT assets can be searched quickly and conveniently. The procedures of IT asset management are saved and working efficiency is improved. Meanwhile, position information management of the IT assets can also be realized according to the strength of received radio frequency signals. Therefore, the problem that the IT assets of an enterprise are prone to being lost due to the fact that the IT assets are not managed by specially-assigned persons is solved.
