Abstract: A computer-implemented method for secure identification of a device being associated at a specific location, thus allowing a user to activate a procedure connected to the specific location where the device is placed, said device being disconnected from internet, comprising the following steps: an enrollment process performed through an application miming on a mobile device, said enrollment process associating the device hardware parameters to the specific location and recording and storing these data on a back-end application miming on a central system; a generation process performed on the device, said generation process generating and displaying on the device a graphical code OTP based with limited lifetime; a validation process of the graphical code OTP based; if the received graphical code OTB based is validated, the user is allowed to activate, through his mobile device, the procedure connected to the specific location.
