Automated number plate recognition systems have always been expensive to install, temperamental to commission and sensitive to any slight differences in font between the plates of neighbouring nations.
Now, technology exists to overcome all these difficulties. Today’s invention is a way to provide on-board ANPR for all cars that are fitted with satnav devices. Each would carry a cheap webcam (or two) which would look at surrounding plates and decide, using software running on a small in-car computer, whether any of these plates was one currently being targetted by security forces.
On finding such a plate, the system would transmit its location (and possibly also its current speed).
