An RFID tag would require an obnoxiously powerful transponder to be read from a great distance, and could not be read without alerting the owner (given appropriately equipped cars). A telephoto lens can read a license plate from a great distance while alerting no one. In the normal case, one would have to be in close proximity to read a car's RFID tag.

- fnordfnordfnord 12y agoYou can detect a car any number of ways. Detect a car without also getting an RFID and you can generate a report for a nearby traffic police to follow up on. We already use RFID for access in a number of places, such as tool booths. An RFID-less car would get noticed there, and I don't see any reason that police vehicles wouldn't be equipped with the transponders, so I think in some cases it might be harder than it currently is.
