RFID Dust Common Questions
Sorry, but there isn't anything like RFID dust.
However, we do get many phone calls from folks looking for a product that can be 'slapped on someone's back and track them all over the world, underground, in the ocean, and possibly even interplanetary.' Or, more importantly, looking for ways to STOP people from tracking them.
But wait... I really think I'm being tracked!
From a technology perspective, the smallest device that could track you at a range of 1-2 miles would be about the size of a quarter and the battery life would be 'hours/days and it wouldn't have an exact GPS coordinate -- just a ping that required guys with BIG antennas to locate you. GPS is super-power hungry, so if you think you are being tracked, look for something the size of a deck of cards. It's mostly battery. That would be under your car, in your luggage, and last about one month and send your GPS location over the cellular network.
There are some super-thin film batteries available now and cellular transmitters the size of an 'iSIM' card. This is the latest (late 2020 tech), and it's 'barely' available. It still couldn't charge the GPS signal enough, so it would have to be a triangulated cellular tower to locate you. These would be difficult to find and could be woven into your clothing. Look for a stiff joint or pocket in your clothes. It might be as small as a 1/2 stick of gum in your cuff or collar.
But, really, it's not our specialty. Contact a security agency with a specialty in counterintelligence. And, get LastPass, change all your passwords to something unique.
