Maybe McCain got a buddy a deal to test it cause it sounds like a waste of money considering they already have plate readers that scan convential plates also every car would need the special place while the current system uses existing cameras and can sacn millions of plates
Automatic number-plate recognition (ANPR) is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data. It can use existing closed-circuit television, road-rule enforcement cameras, or cameras specifically designed for the task. ANPR is used by police forces around the world for law enforcement purposes, including to check if a vehicle is registered or licensed. It is also used for electronic toll collection on pay-per-use roads and as a method of cataloguing the movements of traffic, for example by highways agencies.
Automatic number plate recognition can be used to store the images captured by the cameras as well as the text from the license plate, with some configurable to store a photograph of the driver. Systems commonly use infrared lighting to allow the camera to take the picture at any time of day or night. ANPR technology must take into account plate variations from place to place
Topeka police utilize license plate readers
In the five months since the Topeka Police Department began using automatic license plate readers, the devices have scanned license plates more than 721,500 times.
The readers take a photo of license plates and alert officers if a plate is associated with a stolen vehicle, stolen plate or an Amber or Silver Alert. The plate numbers can be run through databases maintained by the Kansas Bureau of Investigation or the National Crime Information Center.
I got a ticket from Joplin, Mo. one time for running a stop light. Trouble was - I had never ever been in Joplin for 40 years. Even then, I went on a bus to a high school tournament.
I wrote them back, and never heard anything else about it.
