RFID Applications: Tiny Chips For Currency?
The tiny powder RFID chips that Hitachi recently debuted are small enough to be embedded in paper. Reading that in the York Dispatch, it triggered a thought: the US government (collectively) has long desired a way to track paper currency. Some or all American bills have had a thin strip of metal for at least a decade. (My apologies: I don't know which denominations.) But now they may have the means of embedding RFID chips into paper currency.
If you watch enough police dramas on TV like I do, you start thinking of all the times monitoring the literal flow of ransom money would have been helpful. Then there's the other side of the coin, so to speak: the Big Brother scenario, which RFID more than any other technology could support, especially if it becomes as ubiquitous as being in currency. And with RFID in powder form, the potential for abuse grows. Hopefully, that's not the case.
