RFID technology has the ability of being one of the biggest technological advances in my opinion. Radio Frequency Identification uses radio waves to transmit information between an electronic tag and a reader. It is quicker and easier than scanning barcodes and can be used for multiple jobs.
RFID technology has a real future in Law Enforcement. By having RFID chips in peoples license plates, and eventually built right into the cars, Law Enforcement will be able to gain a lot of information about who a car belongs to before ever approaching it, making there job far safer. Some cities have talked about the benefits of using RFID red light "cameras" claiming that they would help to reduce the number of false tickets. This process would use a series of readers placed through the intersection to rule out false crosses which often confuse the cameras.
Europe Develops RFID License Plate Technology
Some people fear that being able to track someone using RFID is a negative thing and in invasion of privacy. They claim that it makes it so the government can know our every move. My answer to this is that if the Government wants to know your every move....it isn't that hard for them. Anyone who believes that is the ultimate intention is naive in my opinion.
