The RFID system is officially intended to deter thieves and other criminals, and it'll also help pinpoint congestion through real-time traffic monitoring. As you might have guessed, though, this raises the prospect of potential abuse. Authorities could theoretically use the tracking to follow the cars of peaceful political activists and others whose only real crime is challenging the status quo. And while officials promise that the associated identification codes are encrypted, there's no absolute guarantee that the tracking data will remain secure. As helpful as the smart stickers could be, there's a real risk that they could hurt a lot of innocent people.
