RFID tags don't need a battery.
- detaro 10y agoIf you want to do any serious "tracking" with them (the rumours I've read talked about them having GPS and being widely traceable), then yes they do. Passive RFID that fits in a bank note might be readable for a tens of meters at the very most, and is trivially shielded by putting it in a metal box. They might put RFID in them, but it won't be the "tracking chip" people imagine.
