Abstract: In a system or device for identifying or tracking tools, the device comprising: a metallic wall delimiting an area wherein a first tool including an RFID tag can be placed, an antenna for communicating with the RFID tag whenever the first tool is in the first area, wherein the antenna is a slot antenna cut out in the metallic wall.

Abstract: A system or device for identifying or tracking tools, the device including a first wall delimiting a first area wherein a first tool including an RFID tag can be placed. The device further includes a first antenna for communicating with the RFID tag whenever the first tool is in the first area, including sending a request signal to the RFID tag and receiving a response signal emitted by the RFID tag in response to the request signal. The device is characterized in that a first control unit configured to set the first antenna with a first frequency and a first power to values fulfilling the following criteria: (1) the first frequency is selected in a predetermined range of RFID frequencies and maximizes the power of the response signal; and (2) the first power is a minimum value enabling the first antenna set with the selected first frequency value to effectively detect the response signal such that an information about the first tool can be extracted therefrom.
