Device for identifying or tracking tools, the device comprising: a first wall delimiting a first area wherein a first tool comprising a RFID tag can be placed; a first antenna for receiving a first radio signal from the RFID tag when the first tool is in the first area, and for generating a first analog signal from the first radio signal; a first analog-to-digital converter, ADC for converting the analog signal into a digital signal; a first processing unit (22, 24) for processing the digital signal; a first housing containing the first processing unit; a second housing containing the first ADC, the second housing being remote from the first housing; a digital link connecting the first housing with the second housing for transmitting the digital signal to the first processing unit; characterized by a first control unit (22, 24) configured to set the first antenna with a first frequency value and a first power value fulfilling the following criteria: the first frequency value is selected in a predetermined range of RFID frequencies and maximizes the power of the first radio signal, which is emitted by the RFID tag in response to a request signal emitted by the first antenna; and the first power value is a minimum value enabling the first antenna set with the selected frequency value to effectively detect the first radio 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 power values; 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 comprising a RFID tag can be placed;
