    I’m not buying that they can scan pet chips. I think that requires closer proximity than their devices can get.

    IDK if they can or not, but I’ve heard they scan car tire pressure sensors. Which apparently, have unique IDs. Unique fingerprint for each car that has 'em. All those fingeprrints put together let them track cars even if the plate is changed.

        The tire sensors, you mean? (nvm this if you meant the pet chips!) Those do use wireless telemetry. It’s easier do like that, and more reliable, than attaching a wire to a rapidly rotating thing through a brushing contact or w/e. Most of them have little batteries, so they actively transmit. Unlike those pet RFID chips which are powered only by the incoming radio signal.

        They also have unique identifiers. Not unique per car. I guess it makes sense in a way. You wouldn’t want to use the TPMS data from a car in the next lane. But it does open up this attack :(

        I wonder what kinda weird looks a person would get, if they ask a tire shop to remove the TPMS modules from their tires, lol
