A device for identifying or tracking tools, the device comprising: a first wall delimiting a first area wherein a first tool including an RFID tag can be placed; 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; characterized by a first control unit configured to set the first antenna with a first frequency and a first power to values fulfilling the following criteria: the first frequency is selected in a predetermined range of RFID frequencies and maximizes the power of the response signal; 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; and wherein the first control unit is configured to perform the following steps: at a first time at which the first tool is in the first area, determining the first frequency value and the first power value by testing different values in the predetermined range of RFID frequencies and different values in a power range; and at a second time after the first time, setting the first antenna with the first frequency value and the first power value determined at the first time, attempting to extract the information about the first tool from the first radio signal, and repeating the determination step only if the attempt fails. a first wall delimiting a first area wherein a first tool including an RFID tag can be placed; 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; characterized by a first control unit configured to set the first antenna with a first frequency and a first power to values fulfilling the following criteria: the first frequency is selected in a predetermined range of RFID frequencies and maximizes the power of the response signal; 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; and wherein the first control unit is configured to perform the following steps: at a first time at which the first tool is in the first area, determining the first frequency value and the first power value by testing different values in the predetermined range of RFID frequencies and different values in a power range; and at a second time after the first time, setting the first antenna with the first frequency value and the first power value determined at the first time, attempting to extract the information about the first tool from the first radio signal, and repeating the determination step only if the attempt fails. the first frequency is selected in a predetermined range of RFID frequencies and maximizes the power of the response signal; 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; and wherein the first control unit is configured to perform the following steps: at a first time at which the first tool is in the first area, determining the first frequency value and the first power value by testing different values in the predetermined range of RFID frequencies and different values in a power range; and at a second time after the first time, setting the first antenna with the first frequency value and the first power value determined at the first time, attempting to extract the information about the first tool from the first radio signal, and repeating the determination step only if the attempt fails. at a first time at which the first tool is in the first area, determining the first frequency value and the first power value by testing different values in the predetermined range of RFID frequencies and different values in a power range; and at a second time after the first time, setting the first antenna with the first frequency value and the first power value determined at the first time, attempting to extract the information about the first tool from the first radio signal, and repeating the determination step only if the attempt fails.
