<p>To provide an easy configurable solution for guaranteeing a control on different objects labelled using RFID tags, it is proposed to apply a method to control the distance of an object labelled by a RFID tag from a telecommunications terminal equipped with a RFID reader and a register module. The method comprises the preliminary step to register the RFID tag at the register module. After an activation of a RFID detection procedure e.g. by the user of that telecommunications terminal, the further step of that method is applied consisting on the measure at repeated time using the RFID reader of the signal strength transmitted via the RFID link between the tag and the RFID reader. An alarm signal is automatically initiated in case that measured signal strength is below a predefined threshold value.</p> |
