&gt; Unless you have a detachable tag, otherwise your tag ID will appear on every single major interception, with time, speed between blocks. Most of Tag will ship to your house, and&#x2F;or auto fill by credit card once the balance is low.<p>In principle there&#x27;s no reason the same thing couldn&#x27;t happen with license plate readers in all but the most dense of traffic. The tags likely make it easier, but with plate-reader technology it should still be possible to do just using license plates.
