Dont see how a patent can be applied to somethign thats been used for years. ANPR cameras for example. Automatic number plate recognition. Cops use it with dash cameras. Read your number plate as you drive, cross check your vehicle registration number on police national computer. This gives them back enough info to know if the car needs to be stopped for no insurance, stolen etc.
