I Googled Microwave RFID U.S. dollars and found photos of the burning in Andrew Jackson's eye. What to believe - RFID tags in the money, magnetic strips for anti-counterfieting, you guys?
Maybe you'se who tried need to leave it in a bit longer? Are you sure it was done?
I believe the U.S. dollars are 'tagged', sure.
Probably more to track the money than the people though. Cash in large piles, not in bank vaults, is likely crime-cash, and they can investigate. Maybe there is a stronger signal when they are together - electronics experts?
Are they tracking individuals? YES. How they would do that with money, since you can get my $20 bill on any given day, I don't know.
BTW, its still bumping me offline, last time with this same message but with links,URLs. Oddly, I was not bumped off with the first post I made today, on topic not about tracking people!! Its a weird life here anymore eh?
