1. An improved ignition interlock system, the system being of the type including: a plurality of ignition interlock devices; for each device, a vehicle in which said each device is installed; and a plurality of service centers, the service centers each having an associated computer adapted to extract data, the improvement comprising:
a wireless transceiver associated with each device; a wireless transceiver associated with each service centre; and computing functionality associated with the service centers and the devices and adapted such that, when any of the vehicles attends at any of the service centers, the computer associated with that service center can extract the data from the device disposed within that vehicle; wherein each device is adapted to enter a lockout condition rendering the vehicle in which it is installed incapable of operation if the time between successive attendances of the vehicle at a service center exceeds a predetermined period; wherein the lockout condition is associated with the time between successive extractions of data from the device and one or more of the time between successive inspections of the vehicle and the time between successive calibrations of the device; and wherein the computing functionality (i) maintains a database, the database including a record for each device, said record including fields containing data which is indicative, at least, of a payment history associated with the device and (ii) is adapted such that, when the device is brought into operative proximity of the service centre, the wireless data extraction occurs automatically, provided that the associated record in the database contains data that indicates that payment has been remitted for the extraction.
