The equipment allows defining different situations to be adjusted to your requirements:

  • User identification: we only identify to the users. It is specially useful for cooperatives that want to identify only the person that is supplying.
  • Vehicle identification: we only identify to the vehicles. It is specially useful for installations where you only want to identify and control the vehicles and their consumption, without identifying the users.
  • User and vehicle identification: It is the more complete system that is offering a high level of security. It is specially useful for installations with a big number of users and/or vehicles, or where the users are often changing the vehicle.
