The RFID transponders are technology that may be used for avoiding misunderstandings in people watching road signs in the streets of a city or highways. Said devices may store a code which may be read by RFID readers located in vehicles, which main function is not only limited to read the content of the transponders, but also interpreting said content with a computer and a database located within the reading device so as to display the information to the user in an easy manner. Additional information may also be stored in a compact manner by using a standardized code for avoiding the need of having an excess of memory fields with long chains of characters. Some related information is: position in a road or city (Kilometre "N" in the highway "N" or Av. "X" in the district "Y" in the city "Z"). Said information may be utilised as a type of coordinates which, with a suitable inner processing performed by the computer and the data base, may provide the position of places such as gas stati ons, parking lots, emergency centres, etc, as well as the position-distance ratio of the same with regard to the location of the user.
