Well, here's some more thoughts...
They said they zapped the money in a stack of 50 bills. The picture looks like the result of a single spark spreading fire damage thoughout the stack, not individual explosions on each and every bill.
A RFID tag small enough to hide in a bill would be a passive chip. These are unpowered, short-range devices that send their serial number to a counting device a few feet from the tag. Long range tracking requires larger RFID tags - about the size of a quarter - with their own power supplies, at least with current technology. I've done a bit of shopping for these things myself, although I wound up deciding that they weren't of much use for my application.
Lastly, I definitely wasn't able to duplicate their results when I microwaved a new 20.
